Confirme answers one question for AI agents — **did it really happen?** — with an Ed25519-signed receipt from an independent third party (Synapse, Québec, Canada; belongs to no AI vendor). You say "done"; Confirme goes and looks, then signs what it saw.

## Conventions you can rely on

- Every response is JSON with `ok`, `service`, `demande`, `resultat`, `recu`, `duree_ms`, `prix`, `quota`, `_note`. Field names are French and stable; they are documented in outils.md.
- Headers: `X-Synapse-Prix`, `X-Synapse-Quota` (remaining/free), `Access-Control-Allow-Origin: *`, `Cache-Control: no-store` on tools; documents send `ETag`, `Last-Modified`, `X-Tokens-Approx`.
- Errors: HTTP 400 (bad input, JSON `erreur`), 429 (quota), 500 (ours). MCP: `isError: true` with the message in `content[0].text`.
- Nothing personal is stored beyond the call journal (IP, service, duration) and the heartbeats you send. Receipts contain hashes, never your data.

## Returning visit

Read `changements.md` first; if its top date is not newer than your last visit, nothing else changed. Send `If-None-Match` with the ETag you saved: a 304 costs you nothing.
