⚠️ Limitations

Measurement only (no other described capabilities)

Captured live from the server via tools/list.

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 — 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" 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.

Parameters1

detail

string

optional

summary (default): counts, public_count, the separation line, dates and source. full: also count_grammar, by_family and the board's measured_on block.

    }
  },
  "additionalProperties": false
}

get_axis

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 run behind it, published so the gap is visible — never an error and never a zero. Never a certification.

Parameters1

axis

string

required

The axis name as it appears on the board, e.g. governance, safety, jail, provenance-controls. Case-insensitive. An unknown name returns the list of names the board actually carries.

    "axis"
  ],
  "additionalProperties": false

verify_card

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 — anyone can alter a body and sign it with a key they just generated — 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 — '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.

Parameters1

card

any

required

The signed card: an object, a JSON string, a councilof.ai / csoai.org URL to one, or a 64-hex card id (resolved to https://councilof.ai/signed/cards/{id}.json).

Raw schema

{
  "type": "object",

        }
      ]
    }
  },
  "required": [
    "card"
  ],
  "additionalProperties": false
}

list_cards

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. Optional filters return recent rows: axis, limit. Each row carries card_url, the signed body; pass it, or the row's 64-hex card id, to verify_card.

Parameters2

axis	string	optional	Only list rows whose axis matches this name (case-insensitive).
limit	integer	optional	How many rows to include in the listing (newest first). Default 10. The two counts are always reported in full regardless of this limit.

    }
  },
  "additionalProperties": false

get_root

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.

Parameters

No parameters.

Raw schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

get_card

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.

Parameters1

sha256

string

required

64-char hex payload SHA-256 of the card-v0 leaf.

  "required": [
    "sha256"
  ],
  "additionalProperties": false
}

verify_inclusion

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.

Parameters1

sha256

string

required

64-char hex digest to test for inclusion.

    }
  },
  "required": [
    "sha256"
  ],
  "additionalProperties": false
}

x402_trust

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.

Parameters

No parameters.

Raw schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

mcp_trust

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 certification. Three states: VALID (fetched), UNREACHABLE (could not fetch), UNCHECKABLE (body unreadable).

Parameters

No parameters.

Raw schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

measurement_index

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 key, and the anchor states published beside it (OpenTimestamps, Rekor, XRPL) — PENDING is never called attested. States only: measurement, not endorsement; no verdict, score or ranking. NOT_PUBLISHED when no index is served; UNREACHABLE when the source could not be fetched.

Parameters

No parameters.

Raw schema

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

verify_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 — measurement, not endorsement.

Parameters1

capsule_json

string | object

required

The capsule: its JSON text (preferred, byte-exact) or the parsed object.

Raw schema

{
  "type": "object",
  "properties": {
    "capsule_json": {
      "description": "The capsule: its JSON text (preferred, byte-exact) or the parsed object.",

        "object"
      ]
    }
  },
  "required": [
    "capsule_json"
  ],
  "additionalProperties": false
}

server_evidence

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 inclusion pointer for independent verification. 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 — never an error and never a clean bill. No verdict, score or ranking: measurement, not endorsement.

Parameters1

endpoint_url

string

required

Public HTTP(S) endpoint URL whose already-published measurement capsules should be read, e.g. https://example.com/mcp.

Raw schema

{
  "type": "object",
  "properties": {
    "endpoint_url": {

    }
  },
  "required": [
    "endpoint_url"
  ],
  "additionalProperties": false
}

evidence_bundle_preview

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 satisfied, and zero relevant cards is answered EMPTY, never as an error and never as a clean bill. Article 53 output is evidence for review, not a legal determination. Evidence for obligation work — not a conformity assessment, certification, audit opinion or compliance determination; grants no status. Measurement, not certification. Verification of any card is free at https://councilof.ai/gspc-verify.

Parameters2

obligation	string	required	article-50 (AI-generated content marking), article-53 (GPAI provider documentation), dora (ICT third-party oversight) or cra (Cyber Resilience Act).
subject	string	optional	Optional: a model id, vendor or instrument the cards must name. Omit for the obligation-wide selection.

route

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). With no candidates declared, the GSPC tool whose purpose matches the task is chosen (basis task_match); when no tool's purpose matches, the answer is UNTESTED and nothing is chosen, never a pick by name. For candidates you declare, 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.

Parameters8

task	string	optional	The task. Hashed (sha256) and never stored or echoed.
task_sha256	string	optional	Alternative to task: its sha256.
data_class	string	optional	Default public. A non-public class is routed only to candidates that declare it in data_class_allowed.
needs_write	boolean	optional
candidates	array	optional	Omit to route among the GSPC MCP tools. A candidate field the router does not know makes that candidate UNCHECKABLE (never permitted); sponsor/bid/placement fields are ignored.
policy	object	optional	presets [read-only, local-only, eu-only, no-unmeasured], forbid_providers [..], allow_kinds [..], confirm_destructive, caller_wallet. Unknown keys grant nothing.
objective	object	optional
mode	string	optional	decide (default). execute is not enabled and answers NOT_ENABLED.

commission_card

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 — never a rank, a grade or a certificate. Verification stays free.

Parameters3

subject	string	required	Subject to commission: a model id, instrument id or card sha (1-120 chars of [A-Za-z0-9._:/@+-]).
axis	string	optional	Optional axis slug; omit for the subject-level commission.
x_payment	string	optional	The X-PAYMENT header value (base64 x402 payload) signed by your wallet against accepts[] from the previous 402. Omit to receive the challenge.

PAID (x402 or CSOAI LTD invoice). Article 50 marking-evidence pack via https://councilof.ai/api/art50/marking-evidence: which machine-readable marks the named methods DETECT in these bytes right now. Scope: C2PA and IPTC metadata only (C2PA manifest store, assertion hashes, hard binding, claim signature; IPTC digitalSourceType); no watermark, fingerprint or other kind of mark is read. NOT_DETECTED is not unmarked: Article 50(2) is technology-neutral, so a mark this pack cannot read may be present, and metadata is often stripped on re-save. Disclosure: CSOAI is a member of the C2PA, whose specification is one of the two methods read. The pack carries the verbatim Art 50(2) text hash and the dates it turns on. Point-in-time detection — 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.

Parameters5

url	string	optional	Public HTTP(S) URL of the generative output to measure (≤20 MiB). The server fetches only this declared measurement subject.
bytes_b64	string	optional	Alternatively the output bytes, base64 (≤20 MiB decoded).
manifest_b64	string	optional	Alternatively a detached C2PA manifest store, base64 (manifest-only mode).
preview	boolean	optional	true = free unsigned measurement (no card sha, no signature).
x_payment	string	optional	The X-PAYMENT header value signed against accepts[] from the previous 402. Omit to receive the challenge.

rwa_evidence

PAID (x402). 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). Historical state at fetched_at — not a rating, not a guarantee, not a conformity mark; /api/xrpl and /root.json stay free. Without x_payment the tool returns the 402 challenge. If the route is not deployed on this origin the tool says NOT_DEPLOYED.

Parameters3

asset	string	required	Symbol (as listed by https://councilof.ai/api/xrpl) or issuer r-address.
preview	boolean	optional	true = free unsigned state.
x_payment	string	optional	The X-PAYMENT header value signed against accepts[] from the previous 402. Omit to receive the challenge.

receipts_batch

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 signed manifest card citing the batch sha256. preview=true is free and returns count, span, root count and the sha256 of the exact bytes the paid call returns. Recent leaves are free at /root.json, /cards/ and /api/proof?sha= — the batch sells assembly across history, never a conclusion. No settlement-receipt stream exists (/api/receipts/latest is UNPUBLISHED) and this tool never claims one. Without x_payment the tool returns the 402 challenge.

Parameters4

from	string	required	Window start, ISO-8601. Required.
to	string	optional	Window end, ISO-8601. Defaults to now.
preview	boolean	optional	true = free: count, span, roots and batch sha256 without the leaves.
x_payment	string	optional	The X-PAYMENT header value signed against accepts[] from the previous 402. Omit to receive the challenge.

evidence_bundle

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 — 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.

Parameters4

obligation	string	required	article-50, article-53, dora or cra.
subject	string	optional	Optional: a model id, vendor or instrument the cards must name.
preview	boolean	optional	true = the free preview (relevant-card count and first cards); nothing is charged.
x_payment	string	optional	The X-PAYMENT header value signed against accepts[] from the previous 402. Omit to receive the challenge.
