OpenAPI Specification

openapi: 3.2.0
info:
  title: AffixIO Verification Verify API
  version: 1.8.0
  description: Public /v1 and /api surface of the AffixIO verification API (ML-DSA-65 signed yes/no results, Noir/Barretenberg circuits, Merkle audit, spent registry, gates, Agent Trust). Generated from the live MCP endpoint catalogue and the Postman collection at https://api.affix-io.com/openapi.postman.json. Account, key, OAuth, Hub and webhook administration are intentionally omitted. A successful verify spends the proof digest; presenting it again returns 409 double_spend_detected. Send Idempotency-Key on prove/verify to retry safely.
