Claim-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.

Layer-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.

OpenTimestamps 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.

A2A 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.

Corrections 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.

Wrapped-asset parity evidence for USDC: every roster pair of that asset read live in one request, one signed card per pair (wrapped supply, escrow balance where an escrow exists, finalized blocks whose hash a second RPC operator confirmed). Per-pair states: ESCROW_PARITY_READ, UNCHECKABLE_NATIVE_ISSUANCE, INDEXED_CUSTODIAL or UNMEASURED. A measurement, not a reserve audit, rating or guarantee. Free preview: https://councilof.ai/api/wrapper/asset/usdc?preview=1. Verification is free.

x402 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.

MCP 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.

Wrapped-asset parity evidence for USDT: every roster pair of that asset read live in one request, one signed card per pair (wrapped supply, escrow balance where an escrow exists, finalized blocks whose hash a second RPC operator confirmed). Per-pair states: ESCROW_PARITY_READ, UNCHECKABLE_NATIVE_ISSUANCE, INDEXED_CUSTODIAL or UNMEASURED. A measurement, not a reserve audit, rating or guarantee. Free preview: https://councilof.ai/api/wrapper/asset/usdt?preview=1. Verification is free.

Wrapped-asset parity evidence for DAI: every roster pair of that asset read live in one request, one signed card per pair (wrapped supply, escrow balance where an escrow exists, finalized blocks whose hash a second RPC operator confirmed). Per-pair states: ESCROW_PARITY_READ, UNCHECKABLE_NATIVE_ISSUANCE, INDEXED_CUSTODIAL or UNMEASURED. A measurement, not a reserve audit, rating or guarantee. Free preview: https://councilof.ai/api/wrapper/asset/dai?preview=1. Verification is free.

XRPL issued-asset slice — the assets whose signed xrpl.asset.state card sits on the current public root, from the live reader, with the issuer registry artifact beside it. A read, not a rating.

Fresh measurement capsule: re-measures one declared-vs-observed claim (TOOLS, VERSION or PROTOCOL) about one MCP endpoint, live, at the discovery boundary only — the endpoint's own discovery documents vs its initialize + tools/list answer. Returns CONSISTENT, INCONSISTENT or UNCHECKABLE with sha256 of every read and a board signature pinning the capsule id. Measurement, not endorsement; verification stays free.

Stablecoin universe slice — every asset the frozen discovery index catalogues, with each reader's per-chain deployment reads and every unmeasured asset's own reason. Assets, never supply; a read, not a reserve attestation.

SWIFT-linked bank census slice — every bank named in a dated public notice about the Swift digital-asset MVP, in its notice's own state (LIVE, COMMITTED, DISCOVERED). Mixed identity by design; never a client list.

Independent AI-behaviour measurement artefact over x402 on Base. Measurement, not certification. A 402 is not delivery. Amounts live only in the HTTP 402 accepts[] challenge. Verify free at https://councilof.ai/gspc-verify.

Signed derivative data feed: the signed streams already on the public root, assembled into one document per request. Carries the signals index, the first-fine watch feed, the root and the card index, each block with its own signature and key id and its as_of read from the file. States: each stream as signed, or UNCHECKABLE where its signature cannot be checked. Data only; verification is free and every stream is public at its own URL.

Wrapped-asset parity evidence: change feed showing the delta of wrapped supply and escrow since the previous ledger snapshot. A diff, not a rate or a grade.

Token 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.

x402 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.

MCP 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.
