Fresh402 Agent Intelligence

Seed or review a public JSON OpenAPI 3.0/3.1 contract against its saved baseline/latest observation; return directional compatibility/security findings and explicit uncertainty. No YAML, external-ref crawling or runtime compatibility proof. One fixed workflow charge; internal steps never create separate customer charges. First source use seeds state in this same operation; later observations use returned owned observation_id. Auth: authorized native-USDC x402 v2 on Base, enabled MPP, or an eligible prepaid key plus exact tariff 5 and max_credits. Ordinary unpaid calls return a challenge, not execution. Persist original input, proof and recovery token before submission; exact replay returns retained results without fresh work or another charge. Choose evidence detail before authorization. No free-trial or automatic paid fallback. 0.010 USDC or 4 credits. Limits and scope are authoritative, not a complete audit or compatibility guarantee.

Observes public documents without modifying their source. Execution can charge USDC or prepaid credits, consume trial quota and update Fresh402 records. A new charge requires prior spending authorization. Without billing/trial credentials and with evaluation:true omitted, a valid call returns an unpaid quote without executing the observation. Use Check for on-demand changed/unchanged, hash, cache status and optional text diff across sessions. Exactly one url or real watch_id; URL/rules can create a watch, while watch_id reuses rules and forbids overrides. Save returned ID/hash. First URL observation may return changed:null. max_age_seconds defaults0 (conditional revalidation); positive age permits cached evidence. html_attributes observes selected same-text attribute changes. Public HTTPS, no JavaScript or scheduler. Use Smart Diff for structured changes; when advertised, Website Change Intelligence combines observation and supported evidence in one charge. Walletless first Check: require root instant_evaluation.enabled, then set evaluation:true with valid URL/watch input. One attempt per verified network prefix per approved period, sharing finite capacity; no wallet, key, custom header or proprietary SDK. Exact replay returns retained evidence, not a new fetch;429 never authorizes payment. $0.005 USDC/call on Base (eip155:8453), including cache hits. Needs an x402-capable MCP payment client and funded native-USDC payer; ordinary MCP returns a payment challenge. Optional MPP (root mpp_payments.enabled): mppx, org.paymentauth/credential. Prepaid: X-Fresh402-API-Key plus params._meta["fresh402/prepaid"] {idempotency_key,tariff_version,max_credits}; inspect authenticated quote. Choose one billing method; never auto-pay. Persist original proof/input/private recovery token; recover originals after uncertainty. Circle only if root circle_gateway.enabled. Clients, limits and recovery: https://fresh402.com/docs#payments. Free signed trial: /v3/agent-trial requires an unfunded EOA ownership signature; human Web trial: /v2/trial. Eligibility/capacity may return429. Use only X-Fresh402-Trial-Key plus persisted Idempotency-Key; replay exact tool/input/key. Exhaustion never authorizes a charge.

Reads blockchain state; the observation does not execute transactions or modify the target wallet/contract. An authorized USDC service payment is separate. Execution can charge USDC or prepaid credits, consume trial quota and update Fresh402 records. A new charge requires prior spending authorization. Without billing/trial credentials, a valid call returns an unpaid quote without executing the observation. Observe code, standard proxy slots, common getters, explicitly selected storage/ABI and bounded selected events at one finalized Base address; optionally compare an owned prior snapshot. Selected single-provider evidence only; unknown controls remain unknown. $0.010000 native USDC/call on Base (eip155:8453); compatible x402 or enabled native MPP client required, no Fresh402 token for first purchase. Save proof/input and private recovery token BEFORE paying for full-response-loss protection: REST X-Fresh402-Recovery-Token; MCP params._meta['fresh402/recovery-token']. Recover originals without new RPC/debit; foreign snapshot/cursor forbidden. Provider failure/partial scan is not paid success. observation_saved=false/persistence_error: recover only, never use unsaved IDs. Prepaid needs eligible finalized all-service credits or an original explicit service-specific tariff4 grant; inspect /v3/prepaid/quote/contract_watch and /v3/prepaid/all-services. Historical Web rights unchanged; paying agents do not need their own RPC credentials. Observations30days, private financial recovery7days. Not full history, financial advice or security audit. Clients: https://fresh402.com/docs#payments. Free signed trial: /v3/agent-trial requires an unfunded EOA ownership signature; human Web trial: /v2/trial. Eligibility/capacity may return429. Use only X-Fresh402-Trial-Key plus persisted Idempotency-Key; replay exact tool/input/key. Exhaustion never authorizes a charge.

Combine one scoped website, an optional JSON OpenAPI comparison and selected finalized Base evidence into one bounded release brief. Separate provenance and missing/conflicting evidence; a release-label mention never proves deployment or causality. One fixed workflow charge; internal steps never create separate customer charges. First source use seeds state in this same operation; later observations use returned owned observation_id. Auth: authorized native-USDC x402 v2 on Base, enabled MPP, or an eligible prepaid key plus exact tariff 5 and max_credits. Ordinary unpaid calls return a challenge, not execution.

Use Extract for text, metadata, headings, links, JSON-LD and content hash from one public document; no watch required. No comparison, crawl or JavaScript. CSS scopes HTML; json_pointer selects one JSON value, json_pointers selects1-8 ordered fields; missing selections fail422. feed_mode:entries projects bounded RSS2/Atom; omit for XML-as-text. max_chars defaults20000, clips text but not the full hash; clipped structured data is omitted. For repeat observations use Check, then separately authorize Extract if needed. Use the retained source identity and scoped output to keep agent evidence consistent across sessions. $0.01 USDC/call on Base (eip155:8453), including cache hits. Needs an x402-capable MCP payment client and funded native-USDC payer; ordinary MCP returns a payment challenge. Optional MPP (root mpp_payments.enabled): mppx, org.paymentauth/credential.

Combine selected code/proxy observations, contract-reported token facts and one wallet's single-block ETH/Transfer evidence at one finalized Base block. Shared RPC cache; at most 18 reads. Wallet scope remains a restricted pilot; no complete history or security score. One fixed workflow charge; internal steps never create separate customer charges. Each call selects one finalized Base block. Reuse its contract_snapshot_id only as previous_contract_snapshot for compatible contract comparison; this workflow accepts no observation_id.

Observes public content without modifying its source. Adds a Fresh402 baseline and uses free registration capacity for new watches; never charges USDC or credits. Use free ($0) Register to save a public HTTPS baseline; no trial key, wallet or payment. Required url plus optional content/attribute rules identifies the watch. Save returned watch_id/hash for Check, Smart Diff or OpenAPI Contract Diff. Same URL/rules returns existing state without fetching or refreshing; different rules identify another watch. It is not continuous monitoring. HTML/JSON/text only; no JavaScript, private or authenticated targets. DNS/fetch/quota limits apply, including on repeat calls. For walletless first Check inspect root instant_evaluation.enabled and set evaluation:true; separate /v3/agent-trial requires ownership signing. Connection grants no signing or payment authority.
