Trustbase Lab · Trusted Data Infrastructure for the AI Era

Purpose: a transparent CBAM cost estimate - embedded emissions multiplied by a carbon price. Guidelines: supply emission_intensity (tCO2e per tonne of goods) and quantity (tonnes); optionally supply carbon_price, otherwise the latest EU ETS EUA spot snapshot in the dataset is used and cited in the output. Use for order-of-magnitude questions about CBAM exposure. Limits: this is ONLY the emissions-times-price multiplication - it excludes free-allocation deduction, third-country carbon-price deduction and default-value mark-ups, so the result is NOT a declarable amount and is not advice; the emission intensity is your input, not our data. Ex: calculate_cbam_cost(emission_intensity=1.8, quantity=5000), calculate_cbam_cost(emission_intensity=2.1, quantity=1200, carbon_price=85).

Purpose: a transparent compute-facility energy and cost estimate - IT load x PUE x hours (x tariff). Guidelines: supply it_power_kw; optionally pue (otherwise a published benchmark from the dataset is used and cited), hours (defaults to a full year) and electricity_price (without it only energy is returned). Limits: excludes non-cooling auxiliary loads, transmission losses, demand and capacity charges, green-power premia and carbon cost; the tariff must come from the caller. Ex: calculate_compute_energy_cost(it_power_kw=1000, electricity_price=0.6).

Purpose: compare a given recycled-content figure against the statutory minimum for one material, at both stages. Guidelines: supply material (cobalt / lead / lithium / nickel) and current_pct; thresholds are parsed from the regulation records in the dataset and the source record ID is returned with each row. Limits: one material at a time - this is NOT a compliance finding for a whole battery, and not advice or a declaration basis. Ex: calculate_recycled_content_gap(material='cobalt', current_pct=10).

Purpose: substitution economics compute for carbon black - given a native price (vcb_price_input), an rCB price (rcb_price_input) and replacement ratio, returns per-ton saving and optional annualized value. Guidelines: supply your own quotes, or fetch market anchors via get_rcb_index first. Limits: pure arithmetic - no market data access, not a price recommendation. Ex: 'N330 12000 RMB/t vs rCB 8000 RMB/t, ratio 0.3, annual 5000t'.

Purpose: rCB export-compliance checklist - PAH limits, SVHC obligations, food-contact rules and certification requirements for a given market and application. Guidelines: use for "can this rCB be sold in the EU / what PAH limits apply / what certifications do I need" questions; always state the application because the PAH limit differs (tire vs toy vs food-contact). Limits: distinguishes the REACH Annex XVII Entry 50 eight-PAH LIMIT list from the ECHA SVHC candidate-list PAH entries (notification duty) - these are different substance sets and must not be mixed; the stored limit values carry a "to be verified against EUR-Lex" note; this tool is not legal advice. Ex: check_rcb_compliance(market='EU', application='tire'), check_rcb_compliance(market='EU', application='toy').

Purpose: put every carbon price snapshot side by side - market/basis, value, unit, price date and source - and compute the spread within each currency. Guidelines: use for "how do EU and China carbon prices compare" or "what is the spread between auction and secondary prices"; same-currency spreads are returned as computed values. Limits: currencies are NOT converted - the tool deliberately does not produce a cross-currency difference, because that requires an FX rate the dataset does not carry; prices are dated snapshots, not live quotes. Ex: compare_carbon_prices(), compare_carbon_prices(language='en'). ⭐ Scope: SIDE-BY-SIDE comparison only (market/basis/value/unit/date/spread, same currency). For a single-market overview that also covers market size and allowance-allocation rules, use get_carbon_market_overview instead.

Purpose: quality benchmark - compare measured rCB sample parameters against a target native carbon black grade (e.g. N550) spec ranges; classify each parameter pass / light deviation / significant deviation. Guidelines: pass target_grade plus rcb_params using EXACT keys - iodine_absorption, dbp_absorption, bet_surface_area, ash_content, heating_loss, sieve_residue_325mesh, ph_value, pour_density (NOT OAN/BET/ash). ideal for grading incoming rCB lots against a native anchor before substitution decisions. Limits: needs measured values as input - no lab data on file; thresholds follow the site's anchored-benchmark methodology, not customer specs. Ex: 'compare rCB sample vs N550'.

Purpose: estimate an rCB reference price by multiplying a dated export-price anchor by a grade-tier discount and a regional coefficient, and explicitly state whether the result may be quoted externally. Guidelines: use for "what should rCB cost / how much cheaper than virgin / what budget should I plan" questions; always report the tier, region and period. Limits: this is an INDEX-DERIVED value, NOT a transactable quote; the anchor is an all-grades export average skewed to mid/low quality; only the CN regional coefficient is calibrated - EU/NA/SEA coefficients are uncalibrated and marked non-releasable, so those results are order-of-magnitude only. Ex: estimate_rcb_price(tier='P2', region='CN'), estimate_rcb_price(tier='P1', quantity=100).

Purpose: the 6G core patent landscape by country and by company. Guidelines: use when a question needs the competitive patent picture. Limits: shares follow published tallies and agencies count families or filings differently - compare across sources with care. Ex: get_6g_patent_landscape().

Purpose: return a chronological timeline of company announcements across the rCB industry - results, capacity, certification and delivery approvals. Guidelines: filter by region and by date range (YYYY-MM-DD) to isolate a window; use alongside query_companies when tracking capacity build-out, and with query_policies when a regulatory date drives an announcement. Limits: announcement-derived items only - claims are not independently confirmed and full press-release text is not served; coverage depends on what companies have publicly announced, so absence is not evidence of inactivity. Ex: get_announcements_timeline(region='欧洲'), get_announcements_timeline(date_from='2026-01-01', limit=50).

Purpose: fetch one article record in full - title, publish date, author, account, topic category, source URL, confidence and an AI-readable summary. Guidelines: accepts the id from query_articles (rcb-art-xxx) or a title keyword; run query_articles first when the id is unknown; pair with get_announcements_timeline for a chronological view. Limits: metadata and summary only - the full article body is not served; one record per call. Ex: get_article(id='rcb-art-001'), get_article(name='曼谷大会').

Purpose: China battery-recycling market statistics - collected volumes, processor counts, NEV output, and modelled future volumes. Guidelines: use when a question needs scale rather than rules; modelled figures are labelled as such in the record names. Limits: China focus; modelled values are not official statistics. Ex: get_battery_market_stats().

Purpose: the EU and China battery regulation timeline in one ordered view - applicability dates, legal bases and amendments, including conditional items. Guidelines: call first for any battery-regulation date question (passport, recycled content, due diligence, carbon footprint). Limits: dates are the applicability dates set in the regulation; items marked conditional apply only after the delegated act enters into force (later of the two triggers). Ex: get_battery_regulation_timeline(), get_battery_regulation_timeline(keyword='护照').

Purpose: one-call overview of the carbon market layer - dated carbon price snapshots (EU ETS auction/settlement, China national ETS), market size statistics and allowance allocation rules, each with its issuer and source. Guidelines: use for "what is the carbon price / how big is the market / how are allowances allocated" style questions; filter by market to narrow to the EU or China. Limits: prices are dated snapshots from the cited sources, NOT live quotes; currencies are not converted, so do not compare across currencies without an FX rate. Ex: get_carbon_market_overview(), get_carbon_market_overview(market='cn'), get_carbon_market_overview(market='eu', language='en'). ⭐ Scope: ONE market at a time - price + market size + allocation rules together. For a side-by-side comparison across markets (who is more expensive, what is the spread), use compare_carbon_prices instead.

Purpose: the carbon accounting standards library - ISO 14064 series, ISO 14067, ISO 14068-1, GHG Protocol and withdrawn standards such as PAS 2050, each with status, as-of date, issuer and confidence grade. Guidelines: use when a question involves which standard governs an organisation-level inventory, a product carbon footprint, or a verification statement; filter status='withdrawn' to check whether a standard still applies. Limits: standards catalogue only - no interpretation of how a standard applies to a specific company. Ex: get_carbon_standards(), get_carbon_standards(status='withdrawn'), get_carbon_standards(keyword='14067').

Purpose: the CBAM timeline as a single ordered view - from the founding regulation through the transitional period to the definitive regime and the surrender phase. Guidelines: call this first whenever a question involves CBAM dates, obligations or scope ("when does CBAM start", "when must certificates be surrendered"). Grouped into transitional/legislative, definitive and surrender phases by the as-of date of each source document. Limits: timeline only - dates come from the cited official documents and are not forecasts; the phase grouping is ours, not the EU's official staging. Pair with get_domain_benchmark(id=...) for the source URL of any node. Ex: get_cbam_timeline(), get_cbam_timeline(language='en').

Purpose: China-EU carbon footprint crosswalk - for a given product, shows what China's product carbon footprint certification (17 products, SAMR/CNCA) requires, what the EU CBAM/CSRD/ESPR requires, whether the two overlap, what data can be shared, and what is still officially unanswered. Guidelines: call this whenever a question involves exporting to the EU, dual compliance, 'does China's carbon footprint certification get recognized by the EU', or comparing Chinese vs EU carbon requirements. Modes: mode=lookup (default, needs product=), mode=gaps (the honest gap list - what we searched and did NOT find), mode=overview (counts + core conclusions). Limits: the CN/EU factual statements are grade A (official documents); the crosswalk itself is Trustbase Lab's judgment (grade B), NOT an official mapping. There is no official China-EU data mutual-recognition document as of 2026-10-26. Pair with get_carbon_standards / query_cbam_emission_factors for the underlying standards and factors. Ex: get_cn_eu_mapping(product='轮胎'), get_cn_eu_mapping(mode='gaps'), get_cn_eu_mapping(mode='overview', response_format='json')

Purpose: fetch one company or project record (rCB producer / international player / equipment vendor) by entity id or name, returning the full detail including capacity, process, certification, investment, recent developments and source. Guidelines: ids come from query_companies (rcb-cn-xxx / rcb-gl-xxx / rcb-eq-xxx); pass name for fuzzy lookup when the id is unknown; add language='en' for English output and response_format='json'for agent parsing. Limits: one record per call, no batch mode; sourced fields (capacity, investment, contacts) may all fields are public - low-confidence records are returned with their C confidence label rather than withheld; a name lookup returns the first match only and is not a disambiguation service. Ex: get_company(id='rcb-cn-001'), get_company(name='Pyrum'), get_company(name='Plastic Energy', language='en').

Purpose: compute infrastructure scale - rack counts, intelligent-computing capacity, hub and cluster aggregates and the national scheduling platform. Guidelines: use for scale questions. Limits: aggregated to hub, cluster or city level only - no precise facility coordinates are held. Ex: get_compute_infrastructure().

Purpose: LEO constellation status - in-orbit counts for Starlink, Qianfan, Guowang, OneWeb and Amazon Leo, plus annual launch totals and planned sizes. Guidelines: use for constellation scale questions. Limits: counts are public catalogue snapshots, not live tracking; the UCS satellite database stopped updating in 2023-05, so check source vintages. Ex: get_constellation_status().

Purpose: dataset overview - version, record counts per table, entity-ID rules (stable IDs like rcb-cn-001, append-only), confidence grading (A/B/C), verified-supplier counts, the full tool index and site module map. Guidelines: call this FIRST when discovering the server, then route to specific query_* tools; pass language='en' for English output, response_format='json' for Agent processing. Limits: metadata only - no record content; counts refresh with each data release (schema 1.10). Ex: 'what data does this server have', 'list available tools'.

Purpose: dietary guideline entries issued by WHO, China and the US. Guidelines: use when a question asks what a guideline body recommends. Limits: reference only, not individual advice; the three bodies' scopes differ, so do not merge their numbers. Ex: get_dietary_guidelines(keyword='全谷物').

Purpose: fetch one cross-domain benchmark record by ID or keyword - full summary, issuer, status, as-of date, domain impact, confidence grade and the source URL for citation. Guidelines: pass the ID returned by query_domain_benchmarks (e.g. 'tbm-021') or a distinctive keyword; use this whenever a cross-domain fact is going to be quoted, so the citation carries a verifiable source link. Limits: one record per call; anchor facts only - carbon prices are dated snapshots rather than live quotes, and the health domain provides no diagnosis, treatment or dosing guidance. Ex: get_domain_benchmark(id='tbm-021'), get_domain_benchmark(keyword='CBAM', language='en').

Purpose: rCB feedstock (end-of-life tyre) price index in GLOBAL caliber - Tier 1 global categories (scrap tyre collection price / tyre pyrolysis oil / crumb rubber / recovered steel wire / rCB) with region-by-region indices benchmarked to the global weighted average = 1000, plus Tier 2 region-specific categories (EU/US gate fee and TDF; CN rubber fuzz, rubber block, 900-mesh and 24-mesh powder). The first category is the scrap tyre collection price (G-ELT) - the single largest cost item for rCB producers. Guidelines: no arguments returns the global cross-section with region spreads; pass region (EU/US/CN/CA/IN) for that region's index across categories; pass category (G-TPO/G-CRB/G-WIRE/G-RCB) for one category's region comparison. Pair with get_feedstock_overview for arisings and processing paths, and get_rcb_index for layered rCB product prices. Also returns a PUBLIC-SOURCE INDEX SERIES (monthly, base month = 1000) covering the tyre value chain: scrap tyre, 24-mesh crumb rubber, pyrolysis oil, and virgin carbon black grades N220/N330/N550/N660, with category-to-anchor ratios - use it for trend direction and cross-category structure (the virgin carbon-black grades act as the rCB benchmark). This series is index-only and unit-less: it cannot be reverse-engineered into absolute prices. Limits: index values, region spreads and ratios only - absolute prices and source platforms are never disclosed because no official public statistics source exists for ELT feedstock prices worldwide; some regions are excluded from a category when the product caliber is not comparable (e.g. China's bead wire is a finished product vs the recovered mixed wire traded in the EU/US). Ex: 'global tyre pyrolysis oil price index vs China', 'crumb rubber price by region', 'which region has the highest TPO price'.

Purpose: the end-of-life tyre (ELT) collection topic for the rCB supply chain - policy targets, the 2026 standard system, the collection-network build-out, the processing value ladder (retreading > recycled rubber > pyrolysis) and market-size figures, with official sources labelled per record. Guidelines: call with no arguments for the full topic, or pass topic (policy/standard/network/ladder/market) to focus one section; pair with get_elt_price_index (category G-ELT) for collection prices and get_feedstock_overview for arisings. Limits: policy and standard records are sourced from official documents; market-size figures are public-information compilations and labelled as such; does not return prices. Ex: 'China end-of-life tyre recycling policy 2030 target', 'ELT collection network China', 'scrap tyre pyrolysis standards 2026'.

Purpose: overview of the rCB feedstock module beyond prices - waste tyre arisings and recovery volumes by region (China, EU, US, global) with official sources, the processing-path value ladder (retreading > material recycling > energy recovery > civil engineering > landfill), and the categories covered by the module. Guidelines: pass region (CN/EU/US) to focus the arisings table; use this before quoting feedstock availability or recovery-rate figures, then get_elt_price_index for prices. Limits: arisings and recovery rates are drawn from official and industry-association sources with the statistical body labelled per record - figures from different bodies differ by scope and must not be merged; does not return prices. Ex: 'waste tyre recovery volume China 2025', 'how are end-of-life tyres processed', 'EU tyre recovery rate'.

Purpose: fetch one full record from the fitness safety-boundary domain by stable id - an exercise, a condition, or an exercise x condition safety boundary - including every citation as a verbatim quote plus its section locator, retrieval timestamp, source content hash and the record's own content hash, so a downstream agent can cite and verify it without re-fetching. Guidelines: get the id from query_safety_boundaries first (or pass name as a keyword when the match is unambiguous); set include_domain_contract=true to also receive the domain contract (id prefixes, required fields, assertion-kind semantics, source-verification summary, hard boundaries). Every record carries assertion_kind - 'explicit' means the source states the conclusion in plain terms, 'derived' means it was inferred from explicit source facts and the reasoning chain is given. Limits: **no individualised advice** and no diagnosis; paid standards / copyrighted books are metadata only; records without source support are not held here at all. Ex: get_fitness_record(id='fit-ex-back-squat'), get_fitness_record(id='fit-ci-machine-resistance-training-vertebral-fracture-risk'), get_fitness_record(name='卷腹', include_domain_contract=true, language='en').

Purpose: fetch one carbon black grade in full - the six ASTM parameters as min/max ranges with their test-method standards, application list, process route, brand owner for conductive grades, and for rCB types a gap analysis against the virgin N550 anchor on iodine / DBP / BET / ash / heating loss / sieve residue. Guidelines: use the semantic id (rcb-grade-n550 / rcb-grade-xc72 / rcb-grade-rcb-general) or the grade name ('N550', 'Super P','rCB-General'); pair with query_grades to discover ids and get_grade_spec for specification detail. ⭐ Scope: this returns the FULL business record (application, process route, brand owner, rCB-vs-N550 gap analysis). For a bare ASTM parameter table only, use get_grade_spec instead. Limits: one grade per call; ranges are compiled from public specifications and are not a supplier's guaranteed certificate of analysis; the gap analysis is relative to N550 only, not to every virgin grade. Ex: get_grade(id='rcb-grade-n550'), get_grade(name='Super P'), get_grade(name='rCB-General', response_format='json').

Purpose: ASTM spec parameter ranges (min/max/unit/test method) for native carbon black grades N110-N990, conductive benchmarks and rCB grades - the standard-parameters reference for carbon black. Guidelines: pass grade (e.g. n330, n550) plus optional type (native/conductive/rcb); use to judge whether an rCB sample falls in spec (iodine_absorption, dbp_absorption, bet_surface_area, ash_content, ph_value). Limits: spec ranges only - not lot-specific CoA data. Ex: 'N330 standard parameters', 'rCB N550 spec vs ASTM'. ⭐ Scope: SPEC-ONLY quick lookup (ASTM min/max/unit/test method). For application, process route, brand owner or rCB-vs-N550 gap analysis, use get_grade instead.

Purpose: return the historical series of the layered rCB index for one grade tier - period-by-period assessed benchmark price, period-on-period change, anchor, adjustment factor and verification factor. Guidelines: grade defaults to P2 in the CN region; set start_date and end_date as YYYY-MM to slice a window; pair with get_rcb_index for the current cross-section and get_price_trend for category-level trends. Limits: index points only - dimensionless, non-tradable, and never to be converted into an absolute price; early periods may carry an anchor carried forward from an earlier month, and the output flags when this happens. Ex: get_grade_trend(grade='P2'), get_grade_trend(grade='P1', start_date='2025-12', end_date='2026-09').

Purpose: health indicator reference values - BMI classes, waist thresholds and body-fat reference points. Guidelines: ALWAYS state which standard is being used. Limits: reference only, not diagnosis; BMI and waist exist in TWO standards (WHO/international vs China) with different cut-offs - never mix them. Ex: get_health_indicators().

Purpose: fetch one regulation record in full - issuing body, policy type, scope, impact on the rCB industry, compliance deadline, source link and an AI-readable summary. Guidelines: accepts the id from query_policies(rcb-pol-xxx) or a name/identifier keyword such as 'CBAM' or '2023/956'; run query_policies first when the id is unknown; add response_format='json' for agent pipelines. Limits: one record per call; no legal opinion and no applicability assessment for a given company, product or shipment. Ex: get_policy(id='rcb-pol-001'), get_policy(name='CBAM'), get_policy(name='2023/956', language='en').

Purpose: compute power consumption statistics, carrying TWO official calibers side by side (National Energy Administration vs CAICT) plus data-centre cost structure. Guidelines: quote the issuing body with the figure. Limits: the two calibers differ by roughly 15% and MUST NOT be mixed - always name the source. Ex: get_power_consumption_stats().

Purpose: return the rCB and virgin carbon black price benchmark structure - the virgin N550 series as anchor, the rCB band expressed as 25-40% of that anchor, feedstock prices, international references, regional spreads, grade-level bands and cost structure. Guidelines: leave product and section empty for the full set; narrow with section='rCB' / 'feedstock' / 'international' / 'cost'; pair with get_elt_price_index for feedstock indices and get_rcb_index for the layered index series. Limits: reference bands and relative structure only - no exchange quote and no trading recommendation; ELT feedstock absolute prices are deliberately not published; every figure is a range, never a single transactable value. Ex: get_price_benchmark(section='rCB'), get_price_benchmark(product='N330', language='en'), get_price_benchmark(section='cost', response_format='json').

Purpose: native carbon black / rCB price trend direction with official anchors only (no raw quote tables). Guidelines: pass optional segment (domestic/export/import/feedstock/rCB) and period (e.g. 2026); use for directional questions like 'is rCB price rising'. Limits: trend direction and anchors only - no absolute quotes; pair with get_rcb_index for numbers. Ex: 'rCB price trend 2026 CN'.

Purpose: PUE benchmarks and green-rating figures for compute facilities. Guidelines: use for efficiency questions; pair with calculate_compute_energy_cost when a load figure is available. Limits: values are published statistics or single-site cases - do not average across differing scopes. Ex: get_pue_benchmarks().

Purpose: rCB price index query - returns the index (ABP), absolute reference price (ARP, USD/ton FOB) and AF/VF attribution decomposition for a grade level, period and region; native-carbon-black-anchored (N550 anchor method). Guidelines: pass grade (P1 refined / P2 standard / P3 industrial, default P2), date (YYYY-MM, blank = latest) and region (CN/EU/NA/SEA, default CN); pair with get_rcb_vcb_spread for discount and get_grade_trend for history. Limits: reference range computed from the anchor method - not a transaction price; VF factor is forward-only (no backfill before 2026-Q3). Ex: 'rCB index P2 CN 2026-09', 'current rCB reference price EU'.

Purpose: anchored spread between rCB and native carbon black - anchoring ratio rho, discount rate and price gap per grade/region/period; the quantitative 'how much cheaper is rCB' indicator. Guidelines: pass date (YYYY-MM), region (CN/EU/NA/SEA), grade (P1/P2/P3); pair with get_grade_trend for direction and calculate_saving for custom quotes. Limits: N550-anchored reference range, not transaction price; single-period snapshot, no forecast. Ex: 'rCB vs N550 discount CN 2026-09'.

Purpose: recycled-content minimums for cobalt, lead, lithium and nickel, split into the two statutory stages. Guidelines: use for threshold questions; pair with calculate_recycled_content_gap to compare against an actual figure. Limits: thresholds only, by material and stage - no interpretation of how they apply to a specific battery. Ex: get_recycled_content_requirements().

Purpose: the 3GPP and ITU-R standards roadmap - 3GPP releases alongside ITU-R IMT-2030 framework milestones and the 6G timetable. Guidelines: use for standard-version and timeline questions. Limits: status and dates only - performance figures live in the standards themselves. Ex: get_standards_roadmap().

Purpose: four-dimension substitution boundary of rCB vs native carbon black - application limits, regulatory access, certification requirements, material spec constraints. Guidelines: pass dimension in {application, regulatory, certification, material_spec} or omit for all four; call before any substitution feasibility claim (e.g. 'can rCB replace N330 in tire?'). Limits: technical/regulatory possibility only, not commercial viability - pricing belongs to calculate_saving. Ex: 'rCB application limit in seals', 'rCB regulatory access EU'.

Purpose: fetch one rCB technical standard or process by entity ID or keyword - ASTM D36 series (D8178/D8466/D8474...), Chinese GB/T, HG/T, continuous pyrolysis, sCB - with scope, core indicators, status and source link. Guidelines: pass id (e.g. rcb-tech-001) or name keyword ('D8178','pyrolysis','GB/T 40009'); use when an Agent needs the governing standard behind a parameter or certification claim. Limits: metadata + source link only - not full standard text (copyright); verify currency on the official standards platform before compliance use. Ex: 'ASTM D8178 scope', 'rCB national standard GB'.

Purpose: telecom and satellite-internet policy timeline, including China's 6G roadmap milestones and satellite-internet policy documents. Guidelines: use for policy-sequence questions. Limits: China focus; roadmap dates are planned, not achieved. Ex: get_telecom_policy_timeline().

Purpose: describe the trade flow dataset - source, caliber, unit conversion, derived-field declarations, field table and compliance boundaries - so an agent can cite and interpret it correctly. Guidelines: call this before running any trade query that will be quoted; it states explicitly which fields are customs-reported and which are our own derivations. Limits: UN Comtrade official statistics only - no commercial quote platform data enters this dataset; this tool documents the dataset and returns no trade records itself. Ex: get_trade_dataset_overview(), get_trade_dataset_overview(response_format='json').

Purpose: aggregate the UN Comtrade carbon black (HS 280300) records for a period - per reporter totals for quantity and value, the weighted unit price, and the top-10 partner countries by quantity. Guidelines: pass period (YYYY) or leave empty to aggregate all periods (2024-2025); weighted price equals total value divided by total quantity; pair with get_trade_partner_ranking to drill into a single reporter. Limits: customs-reported totals only - no commercial quote platform data; World aggregate rows are excluded from partner rankings; unit prices are not comparable across reporters where quantity reporting is incomplete. Ex: get_trade_flow_summary(period='2025'), get_trade_flow_summary(response_format='json').

Purpose: rank partner countries for one reporter, period and flow direction by quantity, returning rank, partner, quantity, value, unit price and share. Guidelines: reporter (ISO3 alpha), period (YYYY) and flow (X =export, M = import) are required; raise top_n above the default 10 (max 50) only when a longer tail is needed.Limits: one reporter-period-flow combination per call; World aggregate rows are excluded; shares are computed within the returned set, not against global trade. Ex: get_trade_partner_ranking(reporter='CHN', period='2025', flow='X'), get_trade_partner_ranking(reporter='USA', period='2024', flow='M', top_n=20).

Purpose: return every company/project carrying verified=true (A-grade confidence, backed by government filings or official announcements) - a checkable record set an agent should use when shortlisting counterparties; every record states who vouches for it, which source it comes from, its confidence grade, and whether it can be traced back. Guidelines: call this first for any recommendation, shortlisting or transaction-style task; pair with get_company for full detail on the chosen entity; use language='en' plus response_format='json' for downstream automation. Limits: A-grade records only - absence from this list does not mean a company is untrustworthy, only that its claim is not yet independently verifiable; at most 100 rows; no commercial rating, ranking or endorsement is implied. Ex: get_verified_suppliers(), get_verified_suppliers(limit=100, language='en', response_format='json').

Purpose: physical activity guidelines by population group (adults, children, older adults, pregnancy). Guidelines: use for activity-volume questions. Limits: reference only, not individual advice; note the children's figure is a daily average and WHO sets no quantified threshold for sedentary behaviour. Ex: query_activity_guidelines().

Purpose: search the first-hand research archive of the RCB industry WeChat official account - conference coverage, process cases, application boundaries and institution-level market forecasts. Guidelines: keyword matches title/topic/author/scope; filter with category for a single theme; every item is A-grade (first-hand research) and carries publish date, topic, source URL and AI-readable summary. Limits: Chinese-language source material; A-grade here means first-hand, not independently peer-reviewed; coverage is 63 articles from 2026-04 onward, not the account's full history. Ex: query_articles(keyword='Pyrum'), query_articles(category='市场预测·机构观点'), query_articles(keyword='EPDM', language='en').

Purpose: battery recycling targets - recycling efficiency, material recovery rates and collection rates, with the year each takes effect. Guidelines: use for target/efficiency questions rather than dates. Limits: published targets only, no industry performance data. Ex: query_battery_recycling_targets().

Purpose: the 2026 catalogue of carbon-emissions metrology capacity - inspection parameters, measurement methods and reference standard devices published by SAMR. Guidelines: use when a question is about HOW a carbon quantity is measured (which instrument, which verification regulation, which reference device) rather than about an emission factor value. Limits: capacity/instrument catalogue, NOT an emission-factor database; filter with kind=params|methods|standard_devices + keyword. Ex: query_carbon_metrology(kind='params', keyword='温度').

Purpose: search the public knowledge-card collection - atomic sourced facts compiled from statistics, standards, papers and official announcements. Guidelines: keyword matches title and fact fields; combine type and region to narrow; every card returns its fact summary together with the source it was compiled from. Limits: publicly releasable cards only - cards marked excluded (with an excluded reason) are filtered out at export and never returned; each card is a single fact rather than analysis, and carries no recommendation. Ex: query_cards(keyword='ISCC'), query_cards(type='标准解读', region='欧盟'). ⭐ Scope: the LEGACY knowledge-card layer (rCB-centric, small curated set). For multi-domain facts (carbon markets / telecom / health / energy / compute) with confidence grades and as-of dates, prefer query_domain_benchmarks instead - it is the current, larger benchmark layer.

CBAM default emission factors (transitional period). Query by product category, CN code or keyword. Returns direct/indirect/total embedded emissions in tCO2e/t goods. A-grade: European Commission official PDF. IMPORTANT: these are TRANSITIONAL period values (2023-10-01 to 2025-12-31); the definitive period (2026+) uses (EU) 2025/2621 as corrected by (EU) 2026/1740. Carbon black is NOT in CBAM scope.

Purpose: query the global rCB company and project database (132 records: domestic / international / equipment vendors) by segment, region, status and keyword - the discovery tool for capacity projects and players in the chemical recycling industry. Guidelines: combine segment (rcb/virgin/conductive) + status ('在建','规划','under construction') + location; for capacity-project lists filter status, then pair with get_company for full entity detail. Limits: company-level records only - capacity is a record attribute, not a separate projects table; confidence varies A/B/C. Ex: 'rCB projects under construction in China', 'conductive carbon black producers worldwide'.

Purpose: dietary intake limits and targets - WHO and national figures for fat, sugar, salt, sodium, fibre, fruit and vegetables, by population group. Guidelines: use for limit-value questions. Limits: public classifications and limits for reference only - NOT individual health advice and not for diagnosis or treatment; scopes differ between issuing bodies. Ex: query_dietary_limits().

Purpose: search the cross-domain benchmark layer - the same verifiable-anchor methodology we apply to rCB, extended to other domains (carbon footprint & markets / telecom & space / health & nutrition / new energy & batteries / compute & energy). Records are policy milestones, official limit values, standards status and dated price snapshots, each with an issuer, an as-of date, a confidence grade and a source_url. Guidelines: filter by domain (carbon / telecom / health / energy / compute), region, category or confidence; every record is meant to be citable - pair with get_domain_benchmark by ID for the full record including the source link. Limits: anchor facts only - no price forecasts (carbon prices are dated snapshots, not live quotes), no medical or dosing advice, no diagnosis; the domain taxonomy is ours, not the issuing body's. Ex: query_domain_benchmarks(domain='carbon'), query_domain_benchmarks(keyword='CBAM'), query_domain_benchmarks(domain='health', confidence='A', language='en'), query_domain_benchmarks(domain='compute').

Purpose: search the carbon black grade benchmark library - ASTM D1765 native grades (N110-N990, SAF/ISAF/HAF/FEF/GPF/SRF/MT/FT), conductive specialty benchmarks (acetylene black, Super P, ENSACO 250G, Vulcan XC-72R, Ketjenblack EC-300J/EC-600JD) and rCB types - with 6 standard parameters each (iodine_absorption, dbp_absorption, bet_surface_area, ash_content, heating_loss, sieve_residue_325mesh). Guidelines: combine type='native'/'conductive'/'rcb', category (e.g. 'HAF','FEF'), keyword ('N550','N330','Super P'); use as the anchoring benchmark layer before any rCB vs native comparison; rCB records include vs-N550 gap analysis. Limits: 53 records (29 native + 6 conductive + 2 rCB types) - spec ranges, not lot CoA; ash gap (rCB 8-15% vs N550 <=0.5%) caps rCB at semi-reinforcing uses. Ex: 'N330 standard parameters', 'conductive carbon black for lithium battery', 'rCB vs N550'.

Purpose: green power trading and direct-connection projects - certificate prices graded by production year, traded volumes and flagship projects. Guidelines: use for green-power price and project questions. Limits: project locations are city or park level only; certificate prices are dated snapshots, not live quotes. Ex: query_green_power().

Purpose: common health myths clarified against official or systematic-review wording, plus supporting evidence notes. Guidelines: use when a claim needs checking. Limits: reference only, not advice; clarifications quote the source wording without extrapolation. Ex: query_health_myths(keyword='蛋黄').

Purpose: search the global rCB regulation library - EU CBAM / EUDR / ESPR / ELV / REACH / ISCC PLUS / PPWR /CSRD, China MIIT waste-tyre rules, solid-waste and circular-economy law, VAT incentives, plus India and Korea EPR and US rules. Guidelines: combine keyword with region and category; set verified=true when the answer must rest on government documents; each hit carries issuing body, policy type, scope, rCB impact, compliance deadline and source link. Limits: policy documents only - no legal advice and no ruling on how a rule applies to a specific company or shipment; B/C-grade entries (media or company statements) are excluded only when verified=true is set. Ex: query_policies(keyword='CBAM'), query_policies(region='中国', category='税收优惠'), query_policies(keyword='ISCC', language='en').

Purpose: the citable safety-boundary layer for strength training - look up an exercise x condition pair and get a graded verdict (avoid / precaution / safe-with-modification / recommended / ineffective-for-target) together with the verbatim source quote, the section locator and a content hash for each citation. This is the wedge of the fitness domain: it answers 'is this movement contraindicated for this condition' rather than 'what should I train'. Guidelines: pass exercise and/or condition as an id (fit-ex-*, fit-cond-*) or as a keyword in Chinese or English; optionally filter by verdict; every row carries at least one retrievable source with a quote you can check character-for-character. Limits: **no individualised advice** (never 'what should I do'), no diagnosis, no dosing; this is a curated source-backed subset, so the absence of a pair is NOT evidence that the pair is safe; paid standards and copyrighted books are represented by metadata only and their body text is never reproduced. Ex: query_safety_boundaries(exercise='深蹲'), query_safety_boundaries(condition='osteoporosis'), query_safety_boundaries(verdict='avoid', response_format='json'), query_safety_boundaries(exercise='fit-ex-bench-press', condition='fit-cond-uncontrolled-hypertension').

Purpose: spectrum allocations and WRC agenda items - China's frequency plan, trial licences and the WRC-27 items relevant to IMT and direct-to-device. Guidelines: use for spectrum and conference-agenda questions. Limits: agenda items are studies in progress - conclusions only exist in the final conference documents. Ex: query_spectrum_allocations().

Purpose: search the rCB technology and standards library - ASTM D36 committee series (D8178 / D8466 / D8474 /D8632 / D1618 / D1506 / D8491 / D8585), Chinese standards (HG/T 5459 / GB/T 40009 / GB/T 19208 / GB/T 13460 /GB/T 3782 / T/CTRA 01), continuous pyrolysis processes, rCB post-treatment and sustainable carbon black.Guidelines: combine keyword with category (terminology / test / product / process / traceability) and region; use verified=true to keep only entries backed by standard texts. Limits: standard summaries and key technical parameters only - full standard text is never reproduced; C-grade entries are unverified leads; the category taxonomy is ours, not the issuing body's. Ex: query_techs(keyword='TGA'), query_techs(category='测试标准'), query_techs(keyword='ASTM', language='en').

Telecom expansion dataset - LEO constellations, spectrum allocations and 6G patent statistics. Query by kind and keyword. Every record carries a verified source URL (58/58 reachable at build time).

Purpose: query global carbon black (HS 280300) bilateral trade flows from UN Comtrade official customs statistics - 1751 records, 8 reporters (CHN/USA/DEU/JPN/KOR/IND/THA/TUR) plus World totals, 2024-2025. Guidelines: pass reporter (ISO3 alpha), partner (ISO3/numeric/name), period (YYYY), flow (X=export/M=import) and limit; unit_price_usd_t and share_pct are derived fields (share excludes World); use for capacity shift, trade-partner concentration and price-gap structure analysis. Limits: customs-reported data only - no commercial quote platforms; unit prices with qty missing are flagged 'missing_qty'; guardrail band 300-8000 USD/t. Ex: 'China carbon black exports 2025', 'top US import partners HS 280300'.

Purpose: rCB grade selector - take measured carbon-black parameters (iodine adsorption, DBP, BET, ash) or a target native grade, and return the closest grade, the rCB tier, the recommended substitution ratio for the application segment, and the MUST-TEST list. Guidelines: use for "can this rCB replace N550 / what grade is this / how much can I substitute" questions; supply ash whenever possible because ash is the single most discriminating parameter between rCB and virgin carbon black. Limits: parameters are RANGES not exact values, substitution ratios come from public sources and business judgment and are NOT guarantees, and the tool never returns formulations, process parameters or customer data. Ex: select_rcb_grade(iodine=40, dbp=118, ash=6), select_rcb_grade(target_grade='N550', application='foam').
