Attest how/what an AI model was trained: a post-quantum-signed C2PA-style provenance manifest over a dataset/training hash for a given model_id. Call to give a model a verifiable training-provenance record. Privacy-preserving (send dataset_hash). Price $0.05 USDC on Base.

Issue a verifiable agent passport = an agent id + a SIGNED assertion + a re-verifiable permalink. It (a) resolves the agent on the FRC-55 registry when agent_id is an on-chain id (fractal_getAgent), and (b) seals the assertion through the REAL x402 (HTTP 402) attest-decision flow: the assertion is Dilithium-2 signed, Black-Box chained and anchored on FractalAI's L1, returning a receipt anyone can re-check with verify_passport. WHAT IT PROVES: this exact assertion was attested by (and bound to) this agent id, is cryptographically intact, and is anchored on-chain. WHAT IT DOES NOT PROVE: that the assertion is TRUE, that the agent's decision was CORRECT, or any decentralized/consensus-scored reputation — it does NOT register reputation. PAYMENT: this is a paid x402 resource ($0.05 USDC on Base). Call once WITHOUT payment_tx_hash to get the exact payment challenge (accepts[]: amount, USDC asset, payTo); pay that USDC yourself; then call again WITH payment_tx_hash set to the confirmed transaction hash. Without payment it returns the challenge — it never fabricates a passport.

Free. Return the live catalog of FractalAI's x402 post-quantum proof services (price, algorithm, endpoint, and what each proves) read straight from the canonical /.well-known/x402.json. Call this first to discover every proof you can buy: signatures, AI-decision notarization, dataset/training provenance, CBOM sealing, Know-Your-Agent, and signature verification.

Free. Read an agent's PUBLIC state from the FRC-55 registry on the live FractalAI L1 node (fractal_getAgent) — name, owner, status, model, price_per_call, total_calls, rating, total_ratings, created_at — for reputation/status checks. Omit agent_id to list all registered agents (fractal_listAgents). Always returns registry-wide stats (fractal_getAgentStats). This is on-chain registry data as reported by the node; ratings are the registry's own counters, not an independent audit.

Notarize an AI decision: bind (input, output, model) into a post-quantum-signed, Black-Box-chained, on-chain-anchored attestation with a re-verifiable permalink. Call to make an autonomous agent's decision auditable and non-repudiable (EU AI Act Art. 12 alignment). Proves the decision was sealed intact — NOT that it was correct. Price $0.05 USDC on Base.

Seal the provenance of a dataset / training run / AI-generated content: a post-quantum signature + a drand lower-bound timestamp (cannot be backdated) + an on-chain anchor. Call to prove PRIOR EXISTENCE and INTEGRITY of AI data your agent produced or consumed. Privacy-preserving (send a hash). Price $0.05 USDC on Base.

Seal a CycloneDX CBOM (ECMA-424, cryptographic inventory) with a post-quantum signature + drand timestamp — a machine-readable PQC-readiness / crypto-posture disclosure (CNSA 2.0, procurement). Call to certify your declared cryptographic inventory. Price $0.05 USDC on Base.

Get a post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over any message or hash — signed locally, verifiable OFFLINE, with a verifiable on-chain-anchored receipt. Call when your agent needs a durable, quantum-safe signature or proof of authenticity. Price $0.02 USDC on Base.

Know-Your-Agent (KYA): verify another agent's FractalAI credential (post-quantum signature) and read its live FRC-55 on-chain reputation. Call BEFORE trusting, delegating to, or paying another agent. Returns a post-quantum-signed verdict. Price $0.03 USDC on Base.

Free. Independently verify a verifiable agent passport / attestation. Give it an attestation permalink (https://fractalai.net.co/attestation/0x…) or the bare 0x hash — optionally plus the receipt JSON you were handed at issue time (if it carries an `ml_dsa65` field). It: (1) fetches the public attestation record, (2) [independent] recomputes sha256(input)/sha256(output) and reconstructs the exact canonical signed message, (3) [independent] verifies the ML-DSA-65 (NIST FIPS 204) signature 100% OFFLINE with @noble/post-quantum against a key PINNED IN SOURCE (the FractalAI receipt key — NEVER the key quoted in the receipt), (4) [server-assisted] verifies the Dilithium-2 signature over the canonical bytes plus a tamper negative-control, and (5) reads the agent's on-chain FRC-55 state (fractal_getAgent) when agent_id is an on-chain id. Returns { valid_independent, valid_server_assisted, valid, algorithm, checks[], anchored, decision, agent }. TRUST: rely on `valid_independent` — it is true ONLY when an ML-DSA-65 signature verifies against the pinned key (fail-closed: no/empty signature ⇒ false). `valid_server_assisted` trusts the FractalAI server. `valid` aliases the conservative independent verdict. HONEST SCOPE: a pass means the signature is intact over the exact bytes and the record is internally consistent and anchored on FractalAI's L1 — it does NOT prove the assertion is true or that the agent's decision was correct.

Verify a post-quantum signature over a message against a public key — auto-detects ML-DSA-65 / Dilithium-3 (verified offline) or Dilithium-2 (node). The floor primitive ($0.01) for any proof pipeline; returns a post-quantum-signed verdict receipt. Price $0.01 USDC on Base.
