Date-scoped variant of our JP MOF / OFAC address list lookup: returns list status for a chosen date instead of only today, using our own previously-recorded list-change log (same underlying data as sanctions.jp.diff / sanctions.ofac.diff -- no new data source). Each jurisdiction result includes a label describing how the value was derived: observed, inferred, assumed_unchanged, or insufficient_data. Factual reference data only; not legal or investment advice.

Assess an x402 counterparty before paying. POST {target:{payto_address}, payment_context?, policy?}; payto may be a 0x EVM (Base) or base58 Solana seller. Returns risk_score 0-100, decision allow/review/block, confidence, coverage, per-dimension signals, key_factors (what drove the score), a ready-to-apply recommended_policy and a risk-priced recommended_bond. Scored from on-chain settlement behaviour, with OFAC sanctions as a hard block.

Independent website QA and pre-handover verification for AI agents. Submit one public website URL. Atinamos loads the real site in desktop and mobile Chromium, checks HTTP and browser failures, failed requests, console errors and warnings, captures screenshots, and returns machine-readable evidence. Poll the returned status_url for results.

Atomic canonical resolution for the registered Robbie George Biography Plate™ identifier. x402 payment grants one endpoint-level retrieval only. It does not grant training, embedding, bulk ingestion, redistribution, resale, synchronization, private-dataset construction, derivative-dataset creation, or Robbie's Razor framework implementation rights.

Fresh probe of your endpoint plus an Ed25519-signed quality attestation (compact JWS, 24h TTL) you can embed in your 402 responses to raise buyer conversion.

Call a Chainlink aggregator latestRoundData directly on Base and return the round with a signed JWS-HS256 receipt. Pass a known pair (ETH/USD, BTC/USD, USDC/USD, DAI/USD, LINK/USD) or an explicit aggregator address; the number is itself on-chain and re-checkable from the feed address + block in the envelope.

Return a signed spot price for a token in a quote currency (default USD) from a public keyless source (CoinGecko). The JWS-HS256 envelope is a provenance receipt an agent keeps for every few-cent call, verifiable via /verify.

Signed USDC/EURe spot rate read directly from the EURe/USDC 0.30% Uniswap v3 pool on Polygon (mid-price from sqrtPriceX96). The on-chain rate behind the euro off-ramp; the envelope carries the exact eth_call slot0() so the number is independently re-checkable. Excludes the pool fee and slippage.

Read balanceOf for a token/holder pair on Base at the current block and return the balance with a signed JWS-HS256 receipt. The envelope carries the exact eth_call (contract, calldata, block) so anyone can re-run it against any Base node.

Read a transaction receipt on Base, compare it against the head block, and return status (success/failed/pending), the block it landed in and a confirmation count, wrapped in a signed JWS-HS256 receipt. Independently re-checkable from the tx block + head block in the envelope.

Attested Hedera network facts: HBAR exchange rate, gas fees, supply, node roster, throughput, topic state. Each response carries the ML-DSA-65 attestation ID of the served snapshot — tamper-evident reference data for agents that must prove what they knew when they acted.

Attested LLM inference: gpt-4o-mini chat completion plus a post-quantum signed, Hedera-anchored attestation binding the prompt hash, response hash, exact model version, and timestamp. Evidence of which model said what, when — for agents whose decisions may be questioned later.

Attested policy evaluation: submit a proposed agent action, its context, and the policy it must satisfy. Returns a verdict with reasoning and the specific clauses applied — then binds hashes of all three inputs into an ML-DSA-65 signed, Hedera-anchored record. Evidence that the policy was evaluated against this action at this time, independently verifiable long after the agent is gone.

Attested sanctions and export-control screening: one call checks OFAC SDN and Consolidated, UN Security Council, UK OFSI, EU financial sanctions, and BIS consolidated screening lists. The response is audit evidence: per-list results, exact list file hashes and versions, query hash, timestamp, ML-DSA-65 signed and Hedera-anchored. Prove you screened, what you screened against, and what it said.

Attested settlement record: the full resolution plus a signed decision_id, an integrity hash over the evidence, and every candle that determined the outcome — a citable artifact for disputes and audit trails. The decision_id is signed by the same wallet that receives payment, so a counterparty can verify its origin offline.

Attested verification-event custody: seal the fact that an identity/liveness/KYC check ran, its method, provider, and result — without the subject's identity ever reaching Rubric. Caller submits an opaque subjectRef (hash it client-side); the sealed record binds event to outcome, ML-DSA-65 signed and Hedera-anchored. Prove a verification happened and what it said, forever, to anyone.

Attested work record for mixed human/robot/agent crews: seal who (or what) did which action, the outcome, and any deviation from plan — the operational log entry that survives an incident investigation or insurance dispute. ML-DSA-65 signed, Hedera-anchored, independently verifiable by any party.
