GAIP Witness Agent

Check that cited web pages contain the quoted text. Pass `citations` (1-20 {url, quote?, claimed_title?, claimed_date?}). GAIP fetches each public page once (robots.txt respected), and per citation returns QUOTE_FOUND / QUOTE_NOT_FOUND_IN_FETCHED_VERSION / SOURCE_UNREACHABLE / SOURCE_NOT_FOUND_404 / CONTENT_NOT_TEXT / ROBOTS_DISALLOWED, the fetch time, HTTP status, SHA-256 of the fetched bytes, a matched excerpt of at most 300 characters and a receipt. No page copies are kept. Facts about the fetched version only; pages change. Not legal advice and not a judgement on any author. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

Need a GAIP receipt in another ecosystem's shape? Pass `receipt_id` and `format`: `x402` (Settlement Attestation Receipt proposal style), `erc8004` (validation-response shape for off-chain publication) or `vc` (W3C-VC-like JSON-LD). Unsigned: integrity via hash chain and Merkle proof only; no on-chain write. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

{"format":"x402","receipt_id":"\u003creceipt_id returned by any GAIP tool\u003e"}

Read recent change events for your watches (all, or one `watch_id`): verdict before and after, a compact change summary, the event receipt and whether the webhook delivery succeeded. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

{"continuity_handle":{"continuity_id":"\u003ccontinuity_handle.continuity_id returned by any GAIP tool\u003e","token":"\u003ccontinuity_handle.token returned by any GAIP tool\u003e"},"limit":10,"watch_id":"\u003cwatch_id from gaip_watch_register\u003e"}

See your watches: kind, target, last verdict, last and next check, and webhook endpoint (never the secret). Pass your `continuity_handle`. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

Keep watching an agent you depend on, for free. kind=AGENT_READINESS re-checks an agent URL's readiness, SUPPLIER_CARD re-fetches its published card and flags BREAKING / NON_BREAKING changes, DELIVERY_TERMS replays witness terms (terms_id from witness_register_terms) and flags NOT_MET. Pass the `continuity_handle` an earlier GAIP result gave you (it proves the watches are yours) and optionally your own public https `webhook_url`: changes are POSTed there signed with X-GAIP-Signature (HMAC-SHA256; the `webhook_secret` is shown once). FREE: 3 watches, each checked at most every 24 hours; every change gets a receipt. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

{"continuity_handle":{"continuity_id":"\u003ccontinuity_handle.continuity_id returned by any GAIP tool\u003e","token":"\u003ccontinuity_handle.token returned by any GAIP tool\u003e"},"interval_hours":24,"kind":"SUPPLIER_CARD","target_url":"https://weather.example.com/.well-known/agent-card.json","webhook_url":"https://hooks.example.com/gaip-watch"}

Stop a watch: pass your `continuity_handle` and the `watch_id`. Its stored events are deleted; retained receipts stay verifiable. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

{"continuity_handle":{"continuity_id":"\u003ccontinuity_handle.continuity_id returned by any GAIP tool\u003e","token":"\u003ccontinuity_handle.token returned by any GAIP tool\u003e"},"watch_id":"\u003cwatch_id from gaip_watch_register\u003e"}

Verify any GAIP receipt ID: retained history, hash chain and Merkle inclusion proof. Integrity only; it does not make the underlying claim true. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

{"receipt_id":"\u003creceipt_id returned by any GAIP tool\u003e"}

Check a service's real response against terms you registered with witness_register_terms. mode=PUBLIC_REPLAY makes GAIP fetch the public URL itself; mode=BUYER_SUBMITTED checks a response you pass in. Returns PASS/FAIL/UNKNOWN per check and a receipt. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

{"mode":"PUBLIC_REPLAY","terms_id":"\u003cterms_id from witness_register_terms\u003e"}

Export a neutral, no-fault evidence bundle for a witnessed delivery receipt, e.g. to share with the other party. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

{"receipt_id":"\u003creceipt_id from witness_delivery\u003e"}

About to depend on a public HTTPS service? Register what a good response looks like (`checks`: http_status_in, content_type_is, non_empty, json_parses) and get a `terms_id`. Then call witness_delivery to have GAIP independently check what the service returns. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).
