Council of AI GSPC

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 — 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 — plus the board's separation line, and as_of dates for the board and for this fetch. Compact by default; pass detail "full

One axis row from the live GSPC board at https://councilof.ai/api/gspc — 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 — a declared slot with no r

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

The published signed-card index (https://councilof.ai/signed/card_index.json): what the index declares (n_cards) and how many rows it actually carries, reported next to — never reconciled with — the count the card store endpoint (https://councilof.ai/api/cards) reports for itself. Two labelled numbers from two surfaces; if they disagree, this tool shows the disagreement rather than picking one

GET the permissionless public-root at https://councilof.ai/root.json. Returns merkle_root, card_count, as_of, and UNMEASURED notes. Separate from GSPC. Three states: VALID (fetched), UNREACHABLE (could not fetch), UNCHECKABLE (body unreadable). Never a certificate.

GET one public-root card-v0 leaf by sha256 (64 hex) from https://councilof.ai/cards/{sha16}.json. UNMEASURED cells stay visible. States: VALID (fetched); NOT_IN_THIS_CORPUS (the id is in the signed card index, not the public root, so use verify_card on it); INVALID (in neither the live root nor the signed card index); UNCHECKABLE (a source could not be read). Not a GSPC measurement-card.

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 — host details withheld; a 402 is NOT delivery; measurement, never certification.

GET the latest MCP handshake trust snapshot (https://councilof.ai/interop/mcp-trust/latest.json): counts of how many internet-facing MCP servers answer a correct initialize handshake, how many respond with an auth challenge, and how many are unreachable. Counts only by doctrine — host details withheld by design. A partial round or a cap change is disclosed in the snapshot. Measurement, never cer

Read the latest signed measurement-capsule index published at https://councilof.ai/measurement-capsules/latest.json: the index root over every capsule, each batch (adapter, kind, capsule count, measurement states, batch Merkle root, record sha256, record signature and OpenTimestamps state), the index's own board signature re-verified here against the pinned did:web:csoai.org#board-attestation-1 ke

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 o

Trust per server, not totals: every published measurement capsule about ONE endpoint URL across all batches — 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) — each with its measurement_state, observed_at, correction_pointer, limitations, batch Merkle root and an

For ONE obligation (article-50, article-53 GPAI transparency, dora or cra) and an optional subject: the obligation record, its counsel-gate status and the already-signed measurement cards that are relevant to it (count plus the first cards, each with its verify link), read live from https://councilof.ai/api/evidence-bundle. Relevant-to is never a determination: no answer says satisfied or not sati

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: pre

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[] w

Per-request signed evidence card of ONE XRPL issued asset's deterministic on-ledger state via https://councilof.ai/api/rwa/evidence: AccountRoot lsf* flags, Domain, the two-way xrp-ledger.toml check (PASS / FAIL / UNCHECKABLE — unreachable is never FAIL), gateway_balances obligation, holders as the free reader has them, every raw fetch sha256'd. preview=true is free (unsigned state)

PAID (x402 or CSOAI LTD invoice). A historical batch of the estate's measurement receipts via https://councilof.ai/api/receipts/batch: every signed card-v0 leaf whose as_of falls in [from,to] (≤200), each with its Merkle inclusion path and the public root(s) that carried it, plus the root index for the window and one manifest card citing the batch sha256. Manifest signing is conditional: a retur

PAID (x402). For ONE obligation (article-50, article-53 GPAI transparency, dora or cra) and an optional subject via https://councilof.ai/api/evidence-bundle: selected existing card objects with signature fields and any retained inclusion proofs, an OSCAL assessment-results wrapper and an assembly manifest. Assembly does not verify input-card signatures. A returned unsigned manifest reports its sig
