Keyless REST API for the GSPC measurement estate: the living board (GET /api/gspc, one axis via ?axis=), the quotable live state, axis register, methodology, signed-card and commission indexes, public root and Merkle inclusion proofs, corrections and press feeds, an Article 50 C2PA-marking detector, XRPL asset evidence, and ten x402-metered doors (request-attestation, proof bundle, evidence-bundle, eunomia-data, rwa/evidence, wrapper, art50/marking-evidence, feeds/provider-diff, receipts/batch, free-door at amount 0) that answer HTTP 402 with the price and a signed offer until paid in USDC on Base. 141 operations across 112 paths, OpenAPI 3.1.0, servers[] https://councilof.ai, CC-BY-4.0; 34 operations carry an x-csoai-lifecycle marker (quarantined / not implemented). A second, read-only 7-operation spec is served at /api/openapi.json.
