description: >-
  LEGIT's one event surface: the watch sentinel. POST /v1/watch (paid per call over x402) puts a 7- or
  30-day sentinel on one tracked merchant; when the merchant's trust state really moves LEGIT records an
  event and, if an https webhook_url was armed, POSTs it once. The provider publishes no AsyncAPI document
  (/asyncapi.yaml and /asyncapi.json both 404 on legit.gonna.bond); this catalog is read from the docs page
  titled "Watch webhooks and events", which the provider calls "the contract".
registration:
  operation: create_watch_v1_watch_post
  path: POST /v1/watch
  body: '{"address": "<merchant address>", "webhook_url": "https://...", "days": 7 | 30}'
  auth: x402 per-call payment ($0.004 algorand-mainnet / $0.005 base-mainnet)
  returns: 201 with the watch id (response schema undeclared in the spec)
  companions:
  - {operation: watch_status_v1_watches__watch_id__get, path: 'GET /v1/watches/{watch_id}', auth: 'watch id (bearer capability), free'}
  - {operation: watch_events_v1_watches__watch_id__events_get, path: 'GET /v1/watches/{watch_id}/events', auth: 'watch id (bearer capability), free', note: 'The source of truth: newest first, capped at 200 events, readable after expiry until GC (default 7 days past expiry).'}
delivery:
  method: POST
  content_type: application/json
  timeout_seconds: 5
  retries: none
  policy: '"v1: best effort, never retried. Each event is POSTed exactly once. A webhook that times out, answers an error or is unreachable is counted in the worker stats and logged, and v1 never retries it. Your receiver should treat the webhook as a nudge, not a queue."'
  latency: '"events fire inside the indexer cycle, so expect the POST about 2-3 minutes after the ts in the body"'
  user_agent: 'stock python-httpx User-Agent (no custom header yet) — "do not whitelist on a fancy agent string"'
  signature: none documented
  dedup: '"Events fire on real transitions only and dedup by state, never by time: while the state that fired an event is unchanged, no repeat event is written."'
payload:
  keys: [watch_id, address, event, kind, ts, detail]
  note: '`event` and `kind` carry the same value; `kind` is an additive alias matching the event-feed rows and "event is never removed". `detail.score` is the score AT the transition, frozen in the event, not the live score.'
  example:
    watch_id: 9f1c2a4b6d8e4f0a1b3c5d7e9f0a1b2c
    address: G7V7U7H6IYRP7BIZO2KV6ODGQPESMMRDCWBYT3GIMNHTNK3VCKWSSKD55A
    event: grade_change
    kind: grade_change
    ts: '2026-08-10T12:00:00'
    detail: {from: A, to: B, score: 71.2}
events:
- kind: grade_change
  fires_when: "The merchant's latest grade differs from the grade recorded on the watch."
  detail: '{"from": "A", "to": "B", "score": 71.2}'
- kind: score_drop
  fires_when: The latest score fell at least LEGIT_WATCH_SCORE_DROP points (default 10) below the recorded score.
  detail: '{"from": 88.5, "to": 71.2, "threshold": 10}'
- kind: outage
  fires_when: One cycle attempted 3 or more probes with zero successes while the recorded state was ok.
  detail: '{"attempts": 3, "ok": 0}'
- kind: recovered
  fires_when: A successful probe returns while the recorded state was outage.
  detail: '{"attempts": 3, "ok": 2}'
