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-storeon tools; documents sendETag,Last-Modified,X-Tokens-Approx. - Errors: HTTP 400 (bad input, JSON
erreur), 429 (quota), 500 (ours). MCP:isError: truewith the message incontent[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.
