Confirme — hub

Start here. What Confirme is, how to call it, where everything else is.

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.
