Method	Path	Description	Price	Network	Asset	402 channel	Captured
GET	/v1/x402/agent-record/rubric-assert	Unforgeable operating history for any AI agent attesting through TenPrint: record count, first-seen date, continuity days, and recent activity, computed from HCS-anchored attestations that cannot be backdated.	$0.005	Base+Sol	USDC, UNKNOWN	header	since 07-28
GET	/v1/x402/attested-inference	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.	$0.01	Base+Sol	USDC, UNKNOWN	header	since 07-28
GET	/v1/x402/hedera-facts/all	All thirteen attested Hedera network facts in one call at GET /v1/x402/hedera-facts/all, each carrying its own attestation ID. A fact whose upstream cannot answer comes back marked unavailable rather than failing the set.	$0.003	Base+Sol	USDC, UNKNOWN	header	since 07-28
GET	/v1/x402/hedera-facts/exchange-rate	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.	$0.001	Base+Sol	USDC, UNKNOWN	header	since 07-28
GET	/v1/x402/regwatch-feed	Structured feed of regulatory changes affecting AI systems: jurisdiction, instrument, change type, effective dates, comment deadlines. Curated snapshot, refreshed monthly. Every item carries its ingest date and a primary source link.	$0.05	Base+Sol	USDC, UNKNOWN	header	since 07-28
GET	/v1/x402/statement	Signed monthly x402 spend statement for one agent: totals, per-payment lines, Merkle root. The statement is itself an ML-DSA-65 attestation anchored to Hedera mainnet HCS. Render, verify, and print the response free at https://rubric-protocol.com/statement.html	$0.50	Base	USDC	header	since 07-28
POST	/v1/x402/tiered-attest	Tamper-evident audit log record for an AI agent decision: signed compliance evidence anchored to public consensus for independent verification. Post-quantum ML-DSA-65 (FIPS 204) signature, Hedera mainnet HCS anchor, free public verification · for agent action provenance, audit trails, and AI governance evidence.	$0.005	Base	USDC	header	since 07-25
GET	/v1/x402/tiered-attest-batch	Batch attestation for AI agent decision streams: up to 1000 leaves under one post-quantum ML-DSA-65 (FIPS 204) signed Merkle root, anchored to Hedera mainnet HCS. Per-leaf attestation IDs with free public verification. $0.035 per batch · tamper-evident audit trails at agentic-telemetry scale.	$0.035	Base	USDC	header	since 07-28
GET	/v1/x402/tiered-attest-batch-xl	Batch attestation for AI agent decision streams: up to 5000 leaves under one post-quantum ML-DSA-65 (FIPS 204) signed Merkle root, anchored to Hedera mainnet HCS. Per-leaf attestation IDs with free public verification. $0.135 per batch · tamper-evident audit trails at agentic-telemetry scale.	$0.135	Base	USDC	header	since 07-28
GET	/v1/x402/verify-audit	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.	$0.002	Base+Sol	USDC, UNKNOWN	header	since 07-28

How the score works

What the score read on this service: status online, 100% uptime 30d, 312ms response p95, x402 compliance 14 of 14, $0.001 price against the category, on-chain traction measured. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

It is a score inside Verification, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 136 listings, this one among them: the same 136 the position above is counted against. When the two differ, the field is the wider one, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Settled via coinbase ($12.48, 397 tx). Traction is a conservative undercount; first settlement seen 2026-07-23.

All measured facts

What it does

Post-quantum attestation and evidence services for AI agents. Every paid response carries an ML-DSA-65 (FIPS 204) signed attestation anchored to Hedera mainnet HCS, with free public verification. Catalog: pay-per-call decision attestation from $0.005, bulk hash anchoring from $0.000027/record, attested gpt-4o-mini inference binding prompt and response hashes to the exact model version, agent operating-history lookups computed from records that cannot be backdated, independent attestation audits with mirror-node confirmation, attested Hedera network facts from $0.001, and a regulatory-change feed for AI systems. A failed mint is never charged.

Rubric Protocol · Post-Quantum AI Attestation is a listed x402 Verification API. Captured payment terms name Base, Solana. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment computed at 2026-10-24 07:43:01 UTC. Uptime uses the stated daily-rollup window; response times are in milliseconds, compliance is passed/evaluated checks, and traction is a measured settlement floor.

Assessment volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Concentrated volume is one rule applied to every listed service: the 3 largest paying addresses hold at least 90% of 30d volume, with at least $10 of volume and 50 settlements in the same 30 days. While it applies, this service's volume counts as 0 in the Recommended and Highest volume sorts of the services list. The label says where the payments came from, not why.

Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.

Daily snapshot total, 30d: $12.04, peak $0.86 on 10-05. The visible 30d total in Traction comes from the latest assessment. These sources can differ in their window, refresh time, cent rounding and shared-address attribution.

Daily address snapshots: 2026-09-25 to 2026-10-24 UTC; * today so far, partial (UTC). Daily snapshots store cents. A recorded $0.00 with settlements cannot distinguish exact zero from volume rounded away. Lost precision is unavailable here. † marks a recorded $0.00 with settlements.

Settlement volume uses the stored USD valuation of tracked payments; it is distinct from token quantities. USD-pegged assets are valued at 1 USD per token in these rollups. The measured settlement floor does not cover all payments to this service.
