## Services monitored

- attestwire.com — Marketing site and rule reference (https://attestwire.com)
- check.attestwire.com — French e-invoicing readiness checker (https://check.attestwire.com)
- api.attestwire.com — Hosted EN 16931 validation API (https://api.attestwire.com/docs)
- vies.attestwire.com — VIES availability monitor (https://vies.attestwire.com)

## Checks

Each check states its own pass condition; a 200 with the wrong body is a
failure, not a success.

- GET https://attestwire.com/ — GET / — must return 200 and render the site.
- GET https://attestwire.com/rules/BR-02 — GET /rules/BR-02 — one real rule page, so a broken build is visible.
- GET https://check.attestwire.com/ — GET / — must return 200 and serve the checker page.
- GET https://check.attestwire.com/api/health — GET /api/health — must return ok:true.
- GET https://api.attestwire.com/v1/health — GET /v1/health — must return ok:true.
- POST https://api.attestwire.com/v1/validate — POST /v1/validate with a real key and a known-good invoice — must return valid:true.
- GET https://vies.attestwire.com/ — GET / — must return 200 and render the board.
- GET https://vies.attestwire.com/api/status.json — GET /api/status.json — generatedAt must be less than 15 minutes old.

## Definitions

- up: the check passed within its latency threshold.
- degraded: it passed but was slow, rate limited, or our own probe budget ran out.
- down: it failed — timeout, 5xx, unexpected status, or a body that did not
  contain what the check requires.
- unknown: we could not run the check. Excluded from uptime, never charged to
  the service.

Uptime = (up + degraded) / (up + degraded + down). No history is backfilled;
windows longer than the monitoring start date are reported as null.

## API

- [Status JSON](https://status.attestwire.com/api/uptime.json): every service and check, current
  status, latency, 24h and 7d uptime, incident feed. CORS-open, cached 60s, no
  key required.

Note: `https://status.attestwire.com/api/status.json` is NOT this API. That path belonged to our
VIES monitor when it lived on this hostname and permanently redirects to
https://vies.attestwire.com/api/status.json.
