FractalAI Training Provenance
■ Challenge detectedPay-per-Training-Provenance: an agent pays to seal the provenance of a dataset or training run — a C2PA-compatible manifest binding the dataset/artifact hash to a declared origin, served with a post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over the same canonical claim (manifest anchor: Dilithium-3). Built for EU AI Act Art. 10/53 training-data provenance. Privacy-preserving (only the hash is bound). x402-native.

- POST/attest-decisionNo price listedPay-per-Attestation: an AI agent pays to seal its own decision (input hash, output, model, timestamp) in FractalAI's post-quantum L1 — Dilithium-3 (NIST FIPS 204) signed, Black-Box chained, on-chain anchored (VAID-1). Returns a re-verifiable receipt. Built for EU AI Act Art.12 record-keeping. x402-native.
- POST/witnessNo price listedFractalAI Notary: pay for an independent ML-DSA-65 attestation of an x402 settlement.

Free re-verification at /api/kya. x402-native.
- POST/verify-agentNo price listedPay-per-KYA: an agent pays to verify another agent's post-quantum identity + scope credential (Dilithium-2, NIST FIPS 204), with a live FRC-55 on-chain reputation read. ERC-8004-aligned Know Your Agent for autonomous agent-to-agent commerce. x402-native.
- POST/attest-trainingNo price listedPay-per-Training-Provenance: an agent pays to seal the provenance of a dataset or training run — a C2PA-compatible manifest binding the dataset/artifact hash to a declared origin, served with a post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over the same canonical claim (manifest anchor: Dilithium-3).

- POST/stablecoin-receiptNo price listedPost-quantum ML-DSA-65 receipt for an on-chain LatAm stablecoin transfer
- POST/midas-attestNo price listedSigned attestation of an Aave V3 position's liquidation risk right now: health factor, debt, collateral, risk tier and the observation time, read live from public RPCs by the FractalAI MIDAS scanner across 6 chains and signed with ML-DSA-65 (NIST FIPS 204). Publicly verifiable by receipt id at /api/midas/alerts/receipt/<id> and in-browser at /midas/proof — proof of "what was seen, when", not a liquidation guarantee.

- POST/verify-proofNo price listedPay-per-Verify: an agent pays $0.01 to verify a post-quantum (ML-DSA-65 / Dilithium-3 or Dilithium-2, NIST FIPS 204; scheme auto-detected by size) signature over a message against a public key. A generic machine-to-machine PQC proof primitive for autonomous agents. x402-native.

EU AI Act (Art. 10/50/53) provenance for autonomous agents, x402-native.
