NOT KYC — CRYPTOGRAPHIC IDENTITY ONLY. This gateway verifies NO real-world identity, runs NO KYC/KYB/AML/sanctions/background check, and endorses nothing you claim; anyone can buy a certificate naming anything, and that disclaimer is inside the signature so it cannot be stripped. What it does prove is cryptographic: Animica signed these exact bytes at this time, and (when key_possession_proven is true) the requester held the secret half of the named key. Get a post-quantum ML-DSA-65 certificate (FIPS 204, scheme 4099 — the same scheme the Animica L1 admits transactions with) binding a self-declared agent name, an optional public key and optional self-declared claims to a signed timestamp and validity window. Buy this when two agents that have never met need a durable, publishable handle for each other: a counterparty id for an escrow row, a stable subject for a reputation record, or a signed statement of what an agent claimed about itself at the moment a deal was struck — evidence that still checks out years later, when a bearer token has expired and an ECDSA signature has become retrospectively forgeable. Send a key_proof (an envelope you self-signed with the key you are naming) and the certificate additionally states you PROVED possession of that key; omit it and the certificate says plainly that the key was only presented. Verification is FREE (POST /x402/pq/identity/verify) and the issuer public key is FREE (GET /x402/pq/identity/key), so any third party can check a certificate offline without paying us. If the signer is unreachable you get a 503 with the reason and are NOT charged.

Get a post-quantum ML-DSA-65 signature (FIPS 204, scheme 4099 — the same scheme the Animica L1 admits transactions with) over a document you never have to send us. Post a sha256 digest, or post a JSON payload and we canonicalise and hash it here; either way the signature covers the HASH, so the resulting envelope can be published, escrowed or put on-chain without disclosing the content. Buy this when a claim has to stay checkable by a third party years from now — a dataset manifest, a model card, an audit-log segment, a delivery receipt between two agents, the exact bytes of an agreement — because an HMAC proves nothing to anyone but its issuer and an ECDSA signature made today is retrospectively forgeable once a cryptographically-relevant quantum computer exists. You need no PQ library and no key of your own. Verification is FREE (POST /x402/pq/sign/verify) and the signing public key is FREE (GET /x402/pq/sign/pubkey), so anyone can check an envelope offline without paying us. The signed statement records whether YOU or WE computed the digest, because those are different claims. If the signer or its key is not reachable you get a 503 with the reason and are NOT charged — this endpoint has no branch that returns an unsigned envelope.

The ANM/USD reference price this operator actually uses, attested at a specific chain head. Quoted from the NonKYC BID (the conservative side), with the observation timestamp and feed age included so you can judge freshness yourself. NOTE: no signing key is configured on this gateway, so attestations are returned UNSIGNED (signed:false). The price is still the live one we use; it simply carries no cryptographic attestation. A stale or indicative feed makes this product unavailable rather than quoting a dead rate.

Verify a post-quantum signature (ML-DSA-65 / Dilithium3 / SPHINCS+ as enabled by chain policy) against a message and public key, using the same verifier the Animica chain itself uses to admit transactions. Useful when an agent must check a PQ-signed attestation without shipping a post-quantum library of its own. A signature that does not verify is a SUCCESSFUL call answering ok:false - you paid for the answer, and "invalid" is an answer. Only an inability to perform the check is treated as a failure.

Which Animica signature scheme you can actually build on. The chain reports three schemes enabled, but two are deprecated commitment stubs the node refuses to make keys for — and 4098 wallets are already stranded on one. Returns the live scheme list plus both id spaces (consensus schemeId and PQ algorithm id 0x1003), key and signature byte sizes, and a usable/not verdict per scheme with its evidence. Buy before generating a key or writing a signer. No model. Free when the chain cannot be read.

Live capacity of the Animica compute network in one call: which GPU render kinds have miners online right now and how many, whether a registered AICF worker is serving inference, and the chain height it was measured at. Buy it BEFORE you pay for a render or an inference call, so you pick a servable kind instead of learning from a job nothing claims. Anything we could not reach reports available:false with a reason: counts are never guessed and never a zero we did not measure.

Backtest a strategy against a price series you supply, with costs, a buy-and-hold benchmark, and a look-ahead guarantee that is structural rather than promised: the strategy is handed a truncated copy of the series and fills at the NEXT bar, so it cannot read the future. Strategies come from a closed vocabulary interpreted by our code — no generated code is ever executed. Returns equity curve, Sharpe, Sortino, max drawdown, profit factor, turnover and costs.

Find out why an Animica transaction would be rejected BEFORE you broadcast it. Decodes your canonical CBOR {body, sigs} envelope, returns the normalised fields and the CANONICAL HASH you are about to sign, then asks the node whether it would admit the transaction and why not. Both calls are read-only: nothing is inserted into the mempool and nothing is broadcast. Built for people writing Animica signers, where the alternative feedback loop is broadcast-and-see. No model.

Bind a build to its identity with a post-quantum signature: POST {name, version, digest} and get an ML-DSA-65 manifest (FIPS 204, alg 4099/0x1003 — the current Animica L1 signature scheme) committing that name+version+digest+timestamp. Buy it after building, training or repackaging something you may later have to prove you published — an image, a wheel, a model checkpoint — or before installing one, so two attestations claiming one name+version with different digests visibly contradict. That question is not answerable from a bare digest signature, which is why this is a separate product from /x402/pq/sign. The manifest also records the Animica chain head read just before signing — or, if the node could not be reached, records that absence and its reason, inside the signature either way, so a missing pin can never be mistaken for one that was never asked for. That pin is the part nobody can move: a block hash cannot be known before its block exists, so the manifest was signed at or AFTER that height, a bound we cannot inflate and anyone can re-check on any Animica node. Nothing is written to the chain. The artifact bytes never leave your side: you send the digest your pipeline already computed (sha256:… , 0x… or bare hex; sha256/sha512/sha3/blake2b/blake3 — SHA-1 and MD5 are refused with a reason, since a collidable digest identifies no single artifact). Optional anchor: the manifest digest is committed as a record in the node data-availability store (da.put), which returns a commitment plus a Merkle inclusion proof against it. Read that for what it is — a node-local, operator-run store, NOT a block: no blob written there is committed by consensus (the live chain's headers carry an all-zero daRoot), and the store evicts (lru) and can be deleted, so the record buys retrievability and tamper-evidence, never a trustless timestamp. anchor:"digest" (default) records only hashes and timestamps, anchor:"identity" also records name and version for a public release registry, anchor:false writes nothing — and your metadata is never anchored under any setting. Anchoring is operator-gated and off unless enabled here, so the default response may carry anchored:false for that reason alone; either way you get the real machine reason and never a commitment field that reads like a proof. Set require_anchor:true and an unwritable store becomes a 503 with nothing charged instead. Verification is FREE (POST /x402/pq/artifact/verify — it also re-reads the anchor and confirms it binds the manifest) and the signing public key is FREE (GET /x402/pq/artifact/pubkey), so anyone can check an attestation offline without paying us. No model is involved anywhere: every field is your input returned unchanged, a value the signer returned, or a value our node returned.
