Paid x402 endpoint for multi-model AI voting and decision synthesis.

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 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.

Attested x402 payment history for any buyer wallet: settlement count, first-seen, last-seen, total spent, services used, distinct sellers observed - computed from an append-only settlement ledger and anchored on Hedera. Counterparty intelligence that is evidence, not opinion: unlike behavioral scores, these records cannot be revised.

Independent audit of a Rubric attestation: signature validity, HCS sequence, and direct Hedera mirror-node confirmation. Returns a signed verdict carrying its own attestation ID — a verification you can cite as evidence.

Structured feed of regulatory changes affecting AI systems: jurisdiction, instrument, change type, effective dates, comment deadlines. Curated by the team behind The Attestation Brief; every item attested on ingest.

Unforgeable operating history for any AI agent attesting through Rubric Protocol: record count, first-seen date, continuity days, and recent activity, computed from HCS-anchored attestations that cannot be backdated.
