GET/api/art50/marking-evidenceArt. 50 marking evidence: one signed pack for one generative output at a named URL, measured from its bytes. Detects C2PA and IPTC metadata only (C2PA manifest, assertion hashes, hard binding, claim signature; IPTC digitalSourceType); no watermark is read. States: DETECTED, NOT_DETECTED (not proof the output is unmarked) or UNCHECKABLE; never a legal determination. CSOAI is a C2PA member. Free unsigned preview; verification is free.$0.01BaseUSDCheadersince 09-14
GET/api/evidence-bundleOSCAL evidence bundle for one obligation: EU AI Act Article 50/53, DORA or EU-CRA. Returns selected card objects with signature fields, any retained inclusion proofs, an OSCAL wrapper and assembly manifest. Does not verify input-card signatures. Reports manifest signing status and any unsigned reason. States: ASSEMBLED or ASSEMBLED-EMPTY; zero selected cards stays zero. Supported-card verification is free at /gspc-verify. No new measurement or conformity determination.$0.01BaseUSDCheadersince 09-14
GET/api/measurement/fresh-capsuleFresh measurement capsule: re-measures one declared-vs-observed claim about one MCP endpoint, live. Compares the endpoint's own discovery documents with its initialize and tools/list answers for TOOLS, VERSION or PROTOCOL, each read hashed; no tool is ever called. States: CONSISTENT, INCONSISTENT, or UNCHECKABLE with the reason. Free unsigned preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/a2aA2A registry population slice: the agents enumerable without a credential from the public A2A registry frame. Counted within that frame, with the estate's own directory-listing state beside it; a frame count, not a global count. States: INDEXED, UNCHECKABLE or UNMEASURED, with n and as_of read at request time. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/claim-watchClaim-maintenance registries slice: each published registry of a vendor's public claims, captured verbatim. Each claim is hashed, source-cited and paired with a measurement plan; file digest, reproducibility and .ots state are read from bytes. CLAIM_CAPTURED, never a claim of falsity. States: INDEXED, UNCHECKABLE or UNMEASURED. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/correctionsCorrections ledger slice: the same entries as free /api/corrections, packaged with per-entry digests. Each entry states what was wrong, how it was caught, the fix and the date; /api/corrections stays free. States: INDEXED, UNCHECKABLE or UNMEASURED, with n and as_of read at request time. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/layer0Layer-0 ceremony slice: every rail and probe of the estate's own machine surface at the ceremony's as_of. Carries the HTTP status each returned and the ceremony artifact's .ots state; self-attestation, dated. States: INDEXED, UNCHECKABLE or UNMEASURED, with n and as_of read at request time. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/mcp-registryMCP registry listings slice: every server name the estate publishes in the official registry, from the census artifact. Each is classified on its latest version, beside the registry's full-walk census and the effect-binding server probe's counts. Distribution, not adoption. States: INDEXED, UNCHECKABLE or UNMEASURED. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/ots-proofsOpenTimestamps proof manifest slice: every published .ots proof of an estate artifact, each state read from its bytes. Rows are Bitcoin-attested, calendar-pending or subject absent; a pending proof is not anchored. States: MEASURED when the rows agree with the manifest, else UNCHECKABLE, or UNMEASURED. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/stablecoinsStablecoin universe slice: every asset the frozen discovery index catalogues, read from the published artifact. Carries each reader's per-chain deployment reads and every unmeasured asset's own reason. Assets, never supply; a read, not a reserve attestation. States: INDEXED, UNCHECKABLE or UNMEASURED, with n and as_of read at request time. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/swiftSWIFT-linked bank census slice: every bank named in a dated public notice about the Swift digital-asset MVP. Each row keeps its notice's own wording (LIVE, COMMITTED, DISCOVERED) and a hashed press URL; mixed identity by design, never a client list. States: INDEXED, UNCHECKABLE or UNMEASURED, with n and as_of read at request time. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/x402-bazaarx402 Bazaar listings slice: the payable resources the two public discovery indexes catalogue, from the census artifact. Counted within each frame, with the overlap published, plus the estate's own door census. Appearing in an index is not delivery. States: INDEXED, UNCHECKABLE or UNMEASURED, with n and as_of read at request time. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/pop/xrplXRPL issued-asset slice: the assets whose signed xrpl.asset.state card sits on the current public root. Read from the live reader, with the issuer registry artifact beside it and never merged. States: INDEXED, UNCHECKABLE or UNMEASURED (a reader that cannot find the locked set is UNMEASURED, never zero). Free preview; verification is free.$0.01BaseUSDCheadersince 09-28
GET/api/ras/mcp-probeMCP discovery probe receipt: one live, read-only discovery of a public https MCP endpoint, signed. Runs server/discover, else initialize and tools/list, and never calls a tool: protocol version requested and negotiated, tool count, tool-names sha256. States include LISTED, PARTIAL, AUTH_REQUIRED, NOT_MCP, TIMEOUT and UNREACHABLE, delivered as found. Verification is free at /api/verify.$0.02BaseUSDCheadersince 09-28
GET/api/ras/supplyToken supply read receipt: one fresh totalSupply() read of an issuer-listed EVM deployment, signed. The address is parsed from the issuer's own page on the request (USDC). States: STATE_PROOF_VERIFIED on Ethereum (EIP-1186 proof checked against the block stateRoot), OPERATOR_API elsewhere, or UNCHECKABLE with the reason. Not a reserve attestation. Verification is free at /api/verify.$0.02BaseUSDCheadersince 09-28
GET/api/ras/x402-checkx402 challenge conformance receipt: one live GET of a public x402 resource, checked and signed. The rule is the daily census's: HTTP 402, a PAYMENT-REQUIRED header, x402Version 2 and extensions.bazaar in the body. States: CONFORMANT, NOT_CONFORMANT, TIMEOUT, UNREACHABLE or BLOCKED, delivered as found. Verification is free at /api/verify.$0.02BaseUSDCheadersince 09-28
GET/api/receipts/batchHistorical measurement-card batch from published roots for a requested time window, capped at 200 leaves. Each signed card-v0 leaf comes with its inclusion path and the root that carried it. States: the leaves found in the window, or an empty batch stated as empty. Not payment or settlement receipts. Free preview (count, span, batch sha256); verification is free.$0.01BaseUSDCheadersince 09-14
GET/api/request-attestationOne named subject gets a card-v0 commission receipt, content-addressed, signed by did:web:csoai.org#board-attestation-1. Without that key: sig_ed25519:null, unsigned_reason. Check csoai.signer before paying. Paid reserve: up to 24 card-v1 references from dated /signed/card-matrix.json only; reserve_count covers that corpus. The interop root in the free preview is not included in the paid reserve. States: SIGNED or UNSIGNED. Payment never creates a MEASURED board cell. Verification is free.$0.01BaseUSDCheadersince 09-07
GET/api/rwa/evidenceRWA asset evidence: one signed card of one XRPL issued asset's on-ledger state, read live per request. Reads the AccountRoot flags, Domain, the two-way xrp-ledger.toml check and the gateway obligation, each raw fetch hashed. States: PROBED, UNCHECKABLE (an unreachable source is never a failure) or UNMEASURED. Free unsigned preview; verification is free.$0.01BaseUSDCheadersince 09-14
GET/api/wrapperWrapped-asset parity evidence: one signed card of one bridged or wrapped token pair, read live from public RPC. Reads the wrapped totalSupply and the origin-chain bridge-escrow balance at finalized blocks whose hash a second RPC operator confirmed, raw reads hashed. States: ESCROW_PARITY_READ, UNCHECKABLE_NATIVE_ISSUANCE, INDEXED_CUSTODIAL or UNMEASURED. UNMEASURED answers 200 preview-only and is never sold. Free preview; verification is free.$0.01BaseUSDCheadersince 09-28

How the score works

What the score read on this service: status online, 100% uptime 30d, 379ms response p95, x402 compliance 14 of 14, $0.01 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 payAI ($0.02, 4 tx). Traction is a conservative undercount; first settlement seen 2026-09-04.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

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.

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.
