art50_marking_evidence
Article 50 marking evidence (paid, x402; preview free)
PAID (x402 or CSOAI LTD invoice). Article 50 marking-evidence pack via https://councilof.ai/api/art50/marking-evidence: is a machine-readable mark DETECTABLE in these bytes right now (C2PA manifest store, assertion hashes, hard binding, claim signature; IPTC digitalSourceType), beside the verbatim Art 50(2) excerpt hash and the Art 99(4) ceiling. Watermarks are UNCHECKABLE where no public detector exists and the pack says so. Point-in-time detection â never a conformity opinion, never a compliance word of any kind. preview=true is free and returns the same measurement unsigned. Without x_payment the tool returns the 402 challenge. If the route is not deployed on this origin the tool says NOT_DEPLOYED rather than inventing a result.

board_totals
Live GSPC board totals
Live GSPC board totals from https://councilof.ai/api/gspc. Returns the slot count and the measured count as two labelled numbers WITH their kind â a slot is a declared position on the board, a measurement is a real run behind it; the two are never summed and never swapped â plus the board's separation line, and as_of dates for the board and for this fetch. Compact by default; pass detail "full" for the long-form count grammar, the per-family counts and the board's full measured_on block. We measure, never certify. If the board cannot be fetched the answer is a distinct UNREACHABLE state: no cached number is ever presented as live.

commission_card
Commission a measurement card (paid, x402)
PAID (x402). Commission one signed card-v0 receipt (surface ras.commission) for a named subject on the frozen bank via https://councilof.ai/api/request-attestation. Re-serves every signed measurement card already on file for the subject; a payment never mints a MEASURED cell (fresh_run stays UNMEASURED until a published run exists). Without x_payment the tool returns the 402 challenge (accepts[] with asset, amount, payTo) plus a free preview of the cards already on file. Measurement, not certification â never a rank, a grade or a certificate. Verification stays free.

evidence_bundle
Evidence bundle for one obligation (paid, x402; preview free)
PAID (x402). An evidence bundle for ONE obligation (article-50, article-53 GPAI transparency, dora or cra) and an optional subject via https://councilof.ai/api/evidence-bundle: OSCAL 1.1.0 assessment-results assembled only from already-signed measurement cards (each with its card bytes and Merkle inclusion proof), plus one manifest card-v0, signed when the signing key is present. Observations are relevant-to the obligation, never satisfied or not satisfied; zero relevant cards ships as an empty bundle, and the free preview says so first (preview=true here, or the free tool evidence_bundle_preview). Article 53 output is evidence for review, not a legal determination. Evidence for obligation work â not a conformity assessment, certification, audit opinion or compliance determination; grants no status. Measurement, not certification. Without x_payment the tool returns the 402 challenge, which is the only place terms appear. Verification of any card is free at https://councilof.ai/gspc-verify.

evidence_bundle_preview
Signed cards relevant to one obligation (free)

Relevant-to is never a determination: no answer says satisfied or not satisfied, and zero relevant cards is answered EMPTY, never as an error and never as a clean bill.

Evidence for obligation work â not a conformity assessment, certification, audit opinion or compliance determination; grants no status. Measurement, not certification.

get_axis
One GSPC board axis
One axis row from the live GSPC board at https://councilof.ai/api/gspc â every axis the board carries, behavioural and financial families alike, addressed by the axis id exactly as the board spells it: n, accuracy, interval, MEASURED or UNMEASURED status, family, kind, the bank or run-artifact URL behind the row, and dates. An unmeasured axis is a first-class answer â a declared slot with no run behind it, published so the gap is visible â never an error and never a zero. Never a certification.

Recent leaves are free at /root.json, /cards/ and /api/proof?sha= â the batch sells assembly across history, never a conclusion.

route
GSPC Route: decide a path under your policy (free, decide-only)
GSPC Route (free, decide-only). Applies YOUR policy and the fixed GSPC floor to a candidate set and returns the chosen candidate, the basis of the choice and an unsigned route record (csoai.evidence-event/0.1, profile csoai.route-evidence/0.1). Candidates are the GSPC MCP tools by default, or ones you declare: your models, your local GPU, MCP tools, A2A agents, x402 resources. Policy is Cedar: presets read-only, local-only, eu-only, no-unmeasured, plus forbid_providers and allow_kinds; anything the router does not understand grants nothing. For the quality axis you name it reads the live board (https://councilof.ai/api/gspc). Routing is not ranking: a choice is called a separated leader only when the board separated that comparison; otherwise it is TIE or UNTESTED and your tie_break decides. A candidate the board holds no number for is UNTESTED, never 0. Sponsor, bid and placement fields are ignored. The task text is hashed, never stored. Nothing is executed, called or charged; mode execute answers NOT_ENABLED. Measurement, not certification.

Trust per server, not totals: every published measurement capsule about ONE endpoint URL across all batches â MCP contract-parity dimensions (AUTH, PAYMENT, PROTOCOL, TOOLS, VERSION), A2A card-signature state, self-parity cells for CSOAI's own doors, and any later adapter (e.g. tool drift) â each with its measurement_state, observed_at, correction_pointer, limitations, batch Merkle root and an inclusion pointer (verify_capsule re-derives inclusion). Read from a static per-endpoint shard keyed by sha256 of the normalised URL. An endpoint with no capsule answers NOT_MEASURED with an empty list â never an error and never a clean bill.

verify_capsule
Verify one measurement capsule
Verify one measurement capsule. Pass capsule_json as the capsule's JSON TEXT (exact: number lexemes are kept) or as an object. Recomputes capsule_id (sha256 of the canonical JSON without capsule_id), picks the rule by the capsule's schema (csoai.measurement-capsule/0.2: RFC 6962 Merkle with 0x00/0x01 domain separation; the superseded v0.1 capsule schema: the v0.1 rule), finds the published batch of the same kind, recomputes that batch's root from its published leaves, and returns the audit path of this capsule against the root named by the signed index. States: INCLUDED, NOT_INCLUDED, ID_MISMATCH, UNCHECKABLE, NOT_PUBLISHED. Verifying is free forever. It proves the bytes were published and bound; what they measured is the capsule's own measurement_state and limitations â measurement, not endorsement.

verify_card
Verify a signed measurement card (free)
Verify a signed gspc.measurement-card under the published rule (https://councilof.ai/signed/HOW-TO-VERIFY.md): recompute the id from the canonical body bytes, then check the Ed25519 signature under a key PINNED in this verifier and published in the did:web:csoai.org DID document: #card-attestation-1 (the card key of the signed card index) or #card-attestation-2 (the card key added on rotation, 27 Sep 2026; a card names the key it was signed under), plus the board key for the cards it signed. pinned_key in the result names the key that matched. A card that carries its own key proves only that the file is self-consistent â anyone can alter a body and sign it with a key they just generated â so an inline key outside the pinned set is reported INVALID, and a DID key reference outside it UNCHECKABLE. Three verdicts, never two: VALID, INVALID (with the reason), or UNCHECKABLE when the check could not be completed â 'could not check' is a different claim from 'forged'. Accepts the card as a JSON object, a JSON string, a councilof.ai / csoai.org URL, or a 64-hex card id (the record id shown on the site and the card field of list_cards), which resolves to https://councilof.ai/signed/cards/{id}.json. Never a certification.

verify_inclusion
Merkle inclusion check
Check a sha256 against the live public-root merkle via GET /api/proof?sha=. Three states only: VALID (included), INVALID (not a leaf), UNCHECKABLE (proof endpoint unreachable). Does not claim Ed25519 unless sig_ed25519 is present and checked separately. Never a grade.

GET the latest x402 catalog trust snapshot: counts of how many catalogued x402 resources open a correct 402 challenge vs how many are phantom on the wire. Counts only by doctrine â host details withheld; a 402 is NOT delivery; measurement, never certification.
