FractalAI PQC Proof Services
Registry code: ad0a0a912cd79fe6
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.…

- Is FractalAI PQC Proof Services live?
- Yes — it answered the hub's last check (checked 9h ago). It answered 100% of checks over the last 30 days.
- Is FractalAI PQC Proof Services free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does FractalAI PQC Proof Services have?
- 13 tools: Sign, Attest Decision, Attest Training, Verify Proof, Witness, Midas Attest, Seal, Verify Agent, ….
- Is FractalAI PQC Proof Services safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 12 doors on this origin, so the chain figures are the operator's. How it is counted.

Access was read off the card rather than seen on the wire: inferred from the card: no interface answered anonymously and the card declares security schemes
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
sign reads 0.02 USDC paid never probed
Pay-per-Proof: one post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over your message or hash. Resistant to known classical and quantum attacks per NIST, not unbreakable. Proves the exact bytes were signed by this server's PQC key; says nothing about their truthfulness.
attest-decision reads 0.05 USDC paid never probed
Seals a declared AI decision: returns a served ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature verifiable OFFLINE, chains it into an append-only Black Box, and attempts an on-chain anchor (VAID-1, Dilithium-2). Returns a re-verifiable attestation receipt. Notarizes the declared decision as submitted; it does not judge whether the decision was correct.
attest-training reads 0.05 USDC paid never probed
Seals the provenance of a dataset or training run: a served ML-DSA-65 / Dilithium-3 (FIPS 204) signature verifiable OFFLINE over a C2PA-compatible manifest (Dilithium-2 cert) binding the dataset/model-artifact hash to a declared origin. Privacy-preserving (only the sha256 hash is bound; raw data never stored). Built for EU AI Act Art. 10/53 training-data provenance. It records the issuer's declaration; it does not verify the data is lawful, consented, unbiased, or actually used to train anything.
verify-proof reads 0.01 USDC paid never probed
Verifies a post-quantum signature over a message against a public key — auto-detects ML-DSA-65 / Dilithium-3 or Dilithium-2 / ML-DSA-44-class by size — and returns a served ML-DSA-65 / Dilithium-3 verdict verifiable OFFLINE. A generic machine-to-machine PQC proof primitive priced at the $0.01 floor. A valid verdict proves only that the signature checks out for exactly this message and public key; it says nothing about who owns the key or the truthfulness of the message.
witness reads 0.005 USDC paid never probed
FractalAI Notary: an INDEPENDENT ML-DSA-65 / Dilithium-3 (FIPS 204) attestation that a given x402 settlement (on ANY resource, ours or a third party's) actually happened on-chain as claimed. When seal_body.transaction is supplied, independently re-derives the transfer from Base RPC and refuses to sign if the claimed asset/payTo/amount don't match what actually landed on-chain — this is not a rubber stamp. Base mainnet only in this version; other networks are refused as UNCHECKABLE.
midas-attest reads 0.01 USDC paid never probed
Signed attestation of an Aave V3 position's liquidation risk RIGHT NOW: health factor, debt, collateral, risk tier and observation time, read live from public RPCs by the FractalAI MIDAS scanner across 6 chains (Ethereum, Base, Polygon, Arbitrum, Optimism, Avalanche) 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 and when — not a liquidation guarantee.
seal reads 0.05 USDC paid never probed
Post-quantum provenance seal: bundles a fresh drand (League of Entropy) round that cannot be backdated with a served ML-DSA-65 / Dilithium-3 (FIPS 204) signature verifiable OFFLINE and an on-chain anchor attempt (Dilithium-2) over your artifact hash. Returns a re-verifiable, timestamped provenance record (useful for EU AI Act Art. 10 & 53 training-data provenance). It is a provenance seal, not a content audit.
verify-agent reads 0.03 USDC paid never probed
Know Your Agent: verifies another agent's post-quantum identity + scope credential — signature, integrity and expiry — plus a live FRC-55 on-chain reputation read, and returns a served ML-DSA-65 / Dilithium-3 (FIPS 204) verdict verifiable OFFLINE. ERC-8004-aligned. Proves the operator declared this identity + scope; it does not prove runtime behavior, nor that the operator is a legitimate entity (that is operator KYC). Reputation, when shown, is a live registry read, not an endorsement.
seal-cbom reads 0.05 USDC paid never probed
Seals a CycloneDX CBOM (ECMA-424 Cryptographic Bill of Materials) with a served ML-DSA-65 / Dilithium-3 (FIPS 204) signature verifiable OFFLINE plus a Dilithium-2 .cbomseal certificate and a drand (League of Entropy) lower-bound timestamp that cannot be backdated. Returns a re-verifiable .cbomseal plus an informational PQC-readiness breakdown. Built for CNSA 2.0 / OMB M-23-02 crypto-posture disclosure. It seals your declared inventory; it does not audit it or certify PQC-readiness.
stablecoin-receipt 0.01 USDC auth-required never probed
Post-quantum receipt for an independently verified on-chain LatAm stablecoin transfer
supplytrack-review auth-required never probed
One deterministic SupplyTrack documentary review with a pinned PQC receipt. Custom bound-order protocol: obtain and persist an unpaid quote, then sign USDC/Base EIP-3009 with its nonce. Not generic x402 auto-payment; no AI or verification of factual accuracy.
issue-kya 0.05 USDC auth-required never probed
Issue a re-verifiable Know-Your-Agent credential signed with ML-DSA-65
sentinel-credit moves money 0.5 USDC auth-required never probed
MIDAS Sentinel credits: 1 credit = 1 ML-DSA-65 (FIPS 204) signed liquidation-risk alert for an Aave V3 position (Ethereum, Base, Polygon, Arbitrum, Optimism, Avalanche), 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), attested by the same key that signs every FractalAI x402 receipt. $0.50 per credit (1–20 per call; the 402 amount = credits × $0.50). Proof of what was seen and when — not protection, not a liquidation guarantee.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your agent card — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idad0a0a912cd79fe6.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/ad0a0a912cd79fe6/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
