GAIP Supplier Watch Agent

Detect breaking changes in an agent or API you depend on. Pass `prior` and `current`: two versions of an A2A agent card, MCP server description, OpenAPI document or a {version, endpoint, permissions, ...} snapshot. Returns each change (skill/tool/operation removed, auth added, endpoint moved, HTTPS downgrade, major version, capability or mode removed) as BREAKING / NON_BREAKING / INFO with impact and migration notes, an overall verdict and a receipt. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

A supplier agent or API started failing? Pass the `failure` ({code, detail}), the supplier's public `supplier_url` and optionally `failure_started_at`. Returns the Integration Repair diagnosis plus the supplier card and readiness changes GAIP observed around that time, each with a receipt and labelled correlated in time (not causation), next steps and an offer to watch the supplier. Free, read-only, no account. Inputs must be public and non-personal; calling declares that (data_classification defaults to PUBLIC).

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).
