⚠️ 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 as_of dates for the board and for this fetch. 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.

Parameters

No parameters.

  "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 the PINNED key published at did:web:csoai.org#card-attestation-1. 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 a signer other than the published key is reported INVALID. 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, or a councilof.ai / csoai.org URL. Never a certification.

Parameters1

card

any

required

The signed card: an object, a JSON string, or a councilof.ai / csoai.org URL to one.

        }
      ]
    }
  },
  "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.

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.

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.

}

get_card

GET one public-root card-v0 leaf by sha256 (64 hex) from https://councilof.ai/cards/{sha16}.json. UNMEASURED cells stay visible. Three states: VALID (fetched), INVALID (not a leaf of the live root), UNCHECKABLE (fetch failed). Not a GSPC measurement-card.

Parameters1

sha256

string

required

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

  ],
  "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.

}

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.

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.

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.

art50_marking_evidence

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 — 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).
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.

  ],
  "additionalProperties": false
}

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.
