FractalAI Pay-per-Proof

Endpoints (10 live)

• POST /api/x402/verify-proof — Pay-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. (0.01 USDC on Base)
• POST /api/x402/seal-cbom — Pay-per-CBOM-Seal: a drand-timestamped, re-verifiable seal over a CycloneDX CBOM (ECMA-424) cryptographic inventory — a Dilithium-3 (NIST FIPS 204) `.cbomseal` cert PLUS an additive ML-DSA-65 / Dilithium-3 (NIST FIPS 204) served signature over the same canonical claim. Built for CNSA 2.0 / OMB M-23-02 PQC-readiness disclosure. Informational readiness breakdown included. x402-native. (0.05 USDC on Base)
• POST /api/x402/seal — Pay-per-Seal: one post-quantum (Dilithium-3) provenance seal + a self-contained ML-DSA-65/Dilithium-3 (NIST FIPS 204) signature — drand-timestamped and on-chain-anchored — over a dataset/training/content hash. EU AI Act (Art. 10/50/53) provenance for autonomous agents, x402-native. (0.05 USDC on Base)
• POST /api/x402/attest-training — Pay-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. (0.05 USDC on Base)
• POST /api/x402/verify-agent — Pay-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. (0.03 USDC on Base)
• POST /api/x402/attest-decision — Pay-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. (0.05 USDC on Base)
• POST /api/x402/sign — Pay-per-Proof: one post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over your message/hash, x402-native. (0.02 USDC on Base)
• POST /api/x402/midas-attest — Signed 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. (0.01 USDC on Base)
• POST /api/x402/witness — FractalAI Notary: pay for an independent ML-DSA-65 attestation of an x402 settlement. (0.005 USDC on Base)
• POST /api/x402/sentinel-credit — MIDAS Sentinel credits: 1 credit = 1 ML-DSA-65 (FIPS 204) signed liquidation-risk alert for an Aave V3 position (6 chains), delivered on the FractalAI chain to the fractal1_pq_ address you name. Credits are FRC-55R service units minted against this payment receipt (evidence_hash = sha256 of the receipt) — the mint is attested by the same key that signs every FractalAI x402 receipt. $0.50 per credit. Proof of what was seen and when — not protection, not a liquidation guarantee. (0.5 USDC on Base)
