Live board totals and the signed public root, free: the axis totals and Merkle root, served through a real x402 settle.

Inclusion proof bundle for leaves available in the last published Merkle root, read from that root. Each leaf comes with its hash, index and proof path, plus the root and the signed card count. States: included with a path, or absent from the root. Verification is free: recompute any path against /r

Art. 50 marking evidence: one signed pack for one generative output at a named URL, measured from its bytes. Reports whether a machine-readable mark (C2PA manifest, assertion hashes, hard binding, claim signature; IPTC digitalSourceType) is detectable now, beside the verbatim Article 50(2) text. Sta

Provider change record: the signed history of document changes the daily watcher recorded for tracked model providers. Each diff leaf comes with its Merkle inclusion proof, assembled per request. States: each diff exactly as the watcher recorded it; the latest state per provider is free at the same

Historical measurement-card batch from published roots for a requested time window, capped at 200 leaves. Each signed card-v0 leaf comes with its inclusion path and the root that carried it. States: the leaves found in the window, or an empty batch stated as empty. Not payment or settlement receipts

Fresh measurement capsule: re-measures one declared-vs-observed claim about one MCP endpoint, live. Compares the endpoint's own discovery documents with its initialize and tools/list answers for TOOLS, VERSION or PROTOCOL, each read hashed; no tool is ever called. States: CONSISTENT, INCONSISTENT, o

Stablecoin universe slice: every asset the frozen discovery index catalogues, read from the published artifact. Carries each reader's per-chain deployment reads and every unmeasured asset's own reason. Assets, never supply; a read, not a reserve attestation. States: INDEXED, UNCHECKABLE or UNMEASURE

SWIFT-linked bank census slice: every bank named in a dated public notice about the Swift digital-asset MVP.
