Capabilities

Tools 44

catalog__call

Run a catalog tool with its arguments. It is validated, limited, billed and answered exactly as a listed tool would be.

Discovered
catalog__describe

A catalog tool's full description and input schema, as tools/list would publish it.

Discovered
catalog__search

Find tools left out of this list (the catalog) by topic. Each hit is a tool name and its first sentence; an empty result means no catalog tool mentions those words.

Discovered
eu_sanctions__search

Search the EU consolidated financial sanctions list (persons and enterprises) by name or alias. Returns matching listed parties with their aliases, listing regulation, and identifying details, plus a `stale` flag when the underlying snapshot is older than the freshness window.

Discovered
ofac_sanctions__search

Search the US Treasury OFAC Specially Designated Nationals (SDN) list (individuals, entities, vessels, and aircraft) by name or alias. Returns matching listed parties with their aliases, sanctions programs, and identifying details, plus `stale`/`available` flags describing how current the underlying snapshot is.

Discovered
ua_bankruptcy__get_case

One bankruptcy case's announcement history and current procedural stage, newest first. `current_stage` is the most recent announcement's type. The registry publishes no case-level status record, so the latest publication is the only statement of where the case stands, and `debtor_code`, `debtor_name` and `court_name` are read off that same announcement. Check `mirror.ready` to tell "no proceedings published" apart from an unsynced mirror.

Discovered
ua_bankruptcy__search

Ukrainian bankruptcy and insolvency announcements (ДСА registry). One result is one published announcement, not one case. A case accumulates announcements as it proceeds and long-running cases have hundreds, so use `get_case` for one case's history and current stage. Company names are stored in full legal form and in capitals, so a distinctive fragment of the trade name works far better than an exact name. `debtor_code` is the reliable way to identify a party.

Discovered
ua_corruption_registry__search

Ukraine's register of persons who committed corruption or corruption-related offences (НАЗК). An entry records one offender, the offence, the article they were held liable under, the sanction, and the court decision or disciplinary decree that imposed it. Most entries are natural persons sanctioned by a court. `sentence_number`, where present, is the decision's ЄДРСР id, so an entry can be checked against the decisions register itself. This source publishes no freshness of its own, so `as_of` is mirror sync date.

Discovered
ua_court_hearings__search

Hearings scheduled in Ukrainian courts (Список справ, призначених до розгляду), every court, read daily from court.gov.ua (a court listing on its own portal instead: source=courtportal). The source lists today onward; past hearings stay here as last listed. Needs case_number, court_code or q.

Discovered
ua_cpi_inflation__search

Ukrainian consumer price index figures over a period range, newest first. This is Derzhstat's own consumer price index, not a producer price index and not the NBU's mixed inflation series. The distinction matters: the month-on-month series (`base_period` PREV_MONTH) is what Article 625(2) of the Civil Code is computed from. An index of 100.0 means no change against its base. Omitting `base_period` returns every base for each period, which is rarely what a calculation wants.

Discovered
ua_debtors__lookup

Every debtor listed under one enforcement-proceeding number. Always a list: one proceeding can be enforced against several debtors, so a number legitimately has several answers.

Discovered
ua_debtors__search

Ukraine's Unified Register of Debtors (Єдиний реєстр боржників, ЄРБ): persons with an open, unsatisfied enforcement proceeding. An entry is dropped at the first daily sync after its proceeding closes, so "not listed" means nothing was open as of `as_of`, never that nothing ever was. The register publishes no dates, so rows carry none and arrive in arbitrary order. `ua_enforcement_proceedings` also holds closed and refused proceedings.

Discovered
ua_echr__get_case

One HUDOC document by `itemid`, adding cited Strasbourg case law, domestic law at issue, judges.

Discovered
ua_echr__search

Search ECHR (European Court of Human Rights) case law via HUDOC, scoped to cases against Ukraine: judgments, decisions and communicated cases with application number(s), engaged articles, importance level, conclusion and a HUDOC permalink, including Ukrainian translations where HUDOC holds one. A live lookup with a short-lived cache, not a stored dataset.

Discovered
ua_edr_companies__lookup

One legal entity by ЄДРПОУ code or `record`, with its people. `people`: founders, beneficial owners, signers and board members; the head is the latest appointment. `company` adds termination, bankruptcy, succession, branches and tax registration. `history`: changes per weekly release since tracking began; `on_date`: people then. Earlier history: paid НАІС extract only. A code shared by several subjects returns the live one, the rest in `other_subjects`. No address or КВЕД codes upstream.

Discovered
ua_edr_companies__lookup_fop

One ФОП by `record`: termination entry and reason, annulled termination, farm-household flag, property manager, tax/ЄСВ registration.

Discovered
ua_edr_companies__search

Ukrainian legal entities in the open ЄДР extract (Єдиний державний реєстр юридичних осіб). Legal entities only; ФОП are `search_fop`. The open extract publishes neither the registered address (місцезнаходження) nor КВЕД activity codes. Both were withdrawn upstream for security reasons, so they are absent rather than lost and no response can supply them; only a paid НАІС/Дія extract carries them. `q` does not reach officers or founders. `lookup` returns those.

Discovered
ua_edr_companies__search_fop

ФОП (фізичні особи-підприємці) in the open ЄДР extract, by name (ПІБ), status and registration/termination date. Ordered by the filtered date, else `record`. No РНОКПП, address or КВЕД upstream: namesakes cannot be told apart, so a name hit alone does not identify a person.

Discovered
ua_edrsr__get_court_practice

Court practice on one statute article: which cases cite it, by court and year, ranked highest authority first. Spellings of one code answer alike ('ККУ', 'КК України') and mean the code in force; `repealed_excluded` lists repealed namesakes' nregs. `index_coverage.status` says what `total_cases` means (a real zero, or unresolved citations); under `index_unavailable` it is null, not a count.

Discovered
ua_edrsr__get_document

One decision: its text, its citations, its structural parts. Text is windowed, never dumped whole. `text_window` says what came back and how to get the rest. Citations cover that window only, with `*_outside_window` counting the rest; repeats of one case roll up into `occurrences`. Citations carry what was written and what it resolved to, so an unresolved one stays visible. Join on `resolved_cause_num`, not the written number. `case_citations` are what this decision cites. Text near a citation is this court's reasoning, not the cited court's.

Discovered
ua_edrsr__lookup_case

One case by document id or case number, with the cases related to it. Give exactly one of `doc_id` or `cause_num`. Metadata only, no reasoning text: what a court held comes from `get_document`. Highest instance first, judgments before rulings, newest first. `related_cases` is citation-graph overlap, never semantic similarity or a judgement on merits, and may repeat a decision from `matches`. `score` weights each shared anchor and case by rarity, so boilerplate ranks near nothing. `departures`/`departed_by`: Supreme Court departures read from the texts.

Discovered
ua_edrsr__search

Faceted full-text search over Ukrainian court decisions (ЄДРСР). Hits are metadata with no reasoning text. What a court held comes only from `get_document`. `doc_type_name` tells a procedural ruling (Ухвала) from a merits judgment without fetching it. `q` is lemmatized inside the index; do not stem it first. Integer filters OR within, AND across. A null `total` is the index not answering, not a no-match.

Discovered
ua_enforcement_proceedings__lookup

Every row published under one enforcement-proceeding number. Always a list: a proceeding with several debtors is published as one row per debtor. `matches` is capped at 200.

Discovered
ua_enforcement_proceedings__search

АСВП, Ukraine's register of enforcement proceedings (виконавчі провадження). Wider than ЄРБ (`ua_debtors`): it keeps closed ('Завершено') and refused ('Відмовлено у відкритті') proceedings too. The shared key is `vp_num`. `debtor_code` is published for legal entities only, about 9% of rows. The source carries no identifier at all for a natural-person debtor, so a null code means the source publishes none, not that parsing failed.

Discovered
ua_holidays__check_date

Whether one date is a public holiday or non-working day in Ukraine. `is_holiday` is true, false, or **null** -- null when `covered` is false, i.e. the mirror has not computed that year. Null is not "no": a deadline calculation must be able to tell "this is a working day" from "this source cannot say". `matches` carries the day with its name and verbatim statute line; a list, as a movable feast and a dated holiday can coincide. `is_holiday` means ст. 73 lists the day. During martial law ст. 73 does not apply: see `martial_law.suspends_holidays`, null past the decreed end.

Discovered
ua_law__get_document

One act's card, by registration number. No text: use `get_document_toc` then `get_unit_fulltext`. `urn_current_edition` is null unless an edition is in force today -- a repealed act has none; `urn_latest_edition` is the newest text in effect today whatever the status; `urn_next_edition`, text scheduled to take effect later. Editions '30000101' and up await a date not yet fixed (e.g. end of martial law) and are none of these.

Discovered
ua_law__get_document_toc

One document's units in reading order -- and the article resolver: `kind='article'` with `number='626'` returns that article alone, `urn` included. Structure only. Each entry carries the `urn` `get_unit_fulltext` takes and a `heading`, or for a clause its opening paragraph as `lead_text` with `text_chars` for the provision's full length. Filter, do not page: the Civil Code is 5,431 units, 1,329 of them articles.

Discovered
ua_law__get_unit

Metadata for one structural unit, addressed by its URN. `urn` is 'urn:ua:law:{nreg}:{path}@{YYYYMMDD}'. Drop '@{YYYYMMDD}' for today's edition; drop the path too for the whole document. Take one from a filtered `get_document_toc` rather than building it. A URN resolving to no unit answers 'not_found' with the nearest real units either side and `same_segment` -- real paths ending in the segment asked for, the hint when the right article was guessed under a wrong ancestor.

Discovered
ua_law__get_unit_editions

The editions on which one unit's text changed, and what changed it. Each entry is a version: its dated `urn`, how many editions kept it, and `amended_by`, the acts behind the change ('unit_notes': cited by the unit's notes; 'edition_basis': the edition's basis). `removed`: the unit disappears; `moved_from`: its address changed (`text_changed` false if only that). A `baseline` opens the list: the first text, or with `from_date` the text in force that day. Edition '30000101' and up (`edition_date` null) takes effect on a date not yet fixed. `complete: false` means `limit` cut older entries.

Discovered
ua_law__get_unit_fulltext

Unit text, paged. Past `max_chars` it is `truncated`: pass `next_cursor` as `cursor` for more. Pages end after a paragraph, else after a space, else mid-word (a tiny `max_chars`). Only page 1 lists `parts`, sub-units with their own `urn`, unless `parts_offset` is passed. `text: null` with status 'edition_text_unavailable' (edition not stored) or 'extraction_failed' (unit not cut out) is a unit that DOES exist -- not a repeal. No unit at that address answers 'not_found'. `text_since`: the edition this text first reads so; `edition_date` only dates the act's latest change.

Discovered
ua_law__get_unit_in_force

Whether one unit was legally in force on a given date. `in_force` is true, false, or null when the corpus cannot tell. `outcome` 'deterministic' is from the portal's own events or edition history, anything else from AI review of the text. An undated URN asks about the provision; a dated one about that version of its text: false once replaced (`scope` 'version', `version_in_force_urn`). `decided_for_provision` false: the answer is the act's, possibly wrong for an article inserted or deleted mid-life. `source: 'no_force_event'`: none ever recorded -- read `document_status_name`.

Discovered
ua_law__get_units_fulltext

Several units' text in one call: a norm and what it relies on. `units` answers each URN in order as `get_unit_fulltext` would, sharing one `max_chars`: a unit that does not fit is `truncated` with a `next_cursor`, and units past the budget come back with no text. A URN matching nothing is its own 'not_found' entry.

Discovered
ua_law__search

Search Ukrainian legislation by free text and/or metadata filters. One entry per matching document, carrying the `nreg` `get_document_toc` takes. Never text. `in_force_on_date` keeps only acts the portal's own commencement and repeal events put in force that day, dropping any act with no such event recorded. `total` counts what it kept; `total_relation: 'gte'` marks a floor.

Discovered
ua_law__search_units

Find provisions by their text: which articles, points or clauses say X. Every word of `text` must appear (quote it for an exact phrase). Searches the text as published on `on_date` (default today); `nreg` limits it to acts. Each hit is the smallest unit holding it, with that day's `urn`. ⟦ ⟧ in `excerpt` mark matches, not the law's text. `amending_act` hits restate other acts. `search` finds acts by title.

Discovered
ua_legal_indicators__court_fee

Судовий збір for a claim, or an appeal/cassation against the judgment, in a civil, commercial or administrative court (ст. 4 Закону № 3674-VI). Base: able-bodied прожитковий мінімум on 1 January of the filing year (minimum wage 2011-2016). Returns amount, formula and provisions. Rates are the law's current text; an older filing may have owed another rate. Not covered (error): special claims, court orders, appeals against rulings, bankruptcy, exemptions.

Discovered
ua_legal_indicators__get

Value of a legal indicator in force on a date, with the act and article that set it. nbu_discount_rate: NBU облікова ставка, % p.a., since 1992. pm_general, pm_child_under_6, pm_child_6_18, pm_able_bodied, pm_disabled: прожитковий мінімум, from 2005. min_wage_monthly (from 2009-11), min_wage_hourly (from 2010). Statutory figures are curated from the budget laws. found=false with a reason: outside coverage, next year's law not curated yet, or NBU not synced. Exchange rates: ua_nbu_rate; CPI: ua_cpi_inflation.

Discovered
ua_lpd__position

One legal position, with its text and published markup. Pass a search hit's `position_id`. `text` is plain, `text_html` as published. `norm_refs` dates each statute quoted to the `ua_law` edition then in force, with a `urn` `ua_law__get_unit_fulltext` takes, to compare with today's text. `departs_from`/`departed_in` link departures, read from position texts; `history` has the detail. `approved_at` is NOT a publication date: its absence says nothing about whether a position is current.

Discovered
ua_lpd__search

The Supreme Court's legal positions (правові позиції). A position is an analyst's short statement of what the Court held, not a quotation, filed under a classifier and linked to its source decisions. ЄДРСР has the judgments, not which passage is the holding: for a Supreme Court position, search here first. Hits omit the text unless `full_text`; `position` serves it. `mark` `indented`: the position departs from (or refines) an earlier holding; `modified`: a later decision departed from or refined it. `norm_refs` dates each norm it quotes to the edition then in force.

Discovered
ua_nbu_rate__rate

Look up the National Bank of Ukraine's official exchange rate (UAH per unit) for a currency, as of a given date or today if none is given. Supports historical dates for ЦК §533 п.2-style currency-conversion calculations, not only the current rate. Returns `available: false` with a null rate, rather than an error, when NBU has nothing published for the requested currency or date.

Discovered
ua_sanctions__search

Ukraine's NSDC (РНБО) sanctions register: individuals, legal persons, vessels. `q`: name/alias words, all required; a code in `q` also matches identifiers. `status`: active, expired (term ended), excluded (cancelled). `source.as_of` = latest decree loaded.

Discovered
ua_vs_digest__document

One Supreme Court publication's extracted text, `document_url`, cited case numbers and linked ЄДРСР `edrsr_ids` -- only this tool returns them. These are analytical reports, not judgments, averaging ~128,000 characters, so a window from the start is usually cover page and contents. Pass `text_query` to open it at the passage you want. `char_count` is the full length; `has_more` whether more follows. `extract_status` says why there is no text: `empty` is a scan with no OCR layer, one in nine; `failed` errored; `unsupported` is not a PDF.

Discovered
ua_vs_digest__search

The Supreme Court's analytical publications: дайджести, огляди and узагальнення судової практики, plus the наукові висновки НКР при ВС. Not in ЄДРСР, which has the judgments but no positions by dispute category: for a Supreme Court position, search here first. `document` returns the text, link and case numbers. `court_body` `vs` is a cross-cutting digest of no single cassation court (a quarter of the corpus), not a missing value.

Discovered
uk_sanctions__search

Search the UK Sanctions List (HM Treasury / FCDO consolidated financial sanctions designations) by name or alias. Returns matching designated parties with their aliases, regime, date of birth and nationality (for individuals), and the sanctions measures imposed. A `stale` flag is set when the underlying snapshot is older than the freshness window, and `retrieved` is false if no snapshot has ever been fetched yet.

Discovered
un_sanctions__search

Search the UN Security Council Consolidated Sanctions List (individuals and entities) by name or alias. Returns matching listed records with their aliases, listing regime (`un_list_type`), and identifying details, plus a `stale` flag when the underlying snapshot is older than the freshness window and a `snapshot.retrieved` flag that is false if no snapshot has ever been obtained yet.
