# FractalAI PQC Proof Services

> Pay-per-call post-quantum proof services for autonomous agents: ML-DSA-65 signatures, decision attestation, provenance seals, CBOM sealing, Know-Your-Agent verification and independent x402 settlement notarization. Every paid response carries an offline-verifiable ML-DSA-65 receipt (3309-byte signature; public key at https://fractalai.net.co/.well-known/jwks.json). ML-DSA-65 per NIST FIPS 204 (CRYSTALS-Dilithium-3) via the open-source @noble/post-quantum library (self-audited, not independently audited). Not a CMVP-validated (FIPS 140-3) module; no government-suite conformance claimed. Pre-pilot, low volume. Transport: plain HTTP+JSON x402 resources (see each skill's x-fractalai.resource); the A2A JSON-RPC message/send method is NOT implemented.
