Council of AI — GSPC Proof Bundle Endpoint
x402
Council of AI — GSPC Proof Bundle Endpoint is a paid API for AI agents from councilof.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-16).
Returns a paid bundle of Merkle inclusion proofs from the GSPC (Global Signed Proof Corpus) board, allowing verification of AI claims against a signed public root.

How this service works
Explore the current GSPC measurements, see the published change record, verify signed evidence, and access the supported public feeds.
Output
A JSON object containing a proof bundle with a list of Merkle inclusion proofs, the current Merkle root (hex), a schema identifier (csoai.public-root-proof/0.1), a kind field ('bundle'), a count (n), and a descriptive note clarifying this is not a grade but a paid bundle of inclusion proofs. Empty cells are represented as empty entries.
Example use cases
Verify a disputed AI ranking claim
“Someone sent me a signed card claiming their AI model scored highly on the GSPC board — can you hit the Council of AI proof endpoint and check whether there's a real Merkle inclusion proof backing that claim?”
Audit AI attestation before partnership
“Before we proceed, I need to verify the AI attestation our vendor provided — can you pull the GSPC proof bundle from Council of AI and confirm the signed root matches their claim?”
Read current GSPC board state
“Can you fetch the current GSPC board from Council of AI and show me the live proof bundle and Merkle root so I can see what AI evaluations are currently on record?”
Technical details
Endpoint
GEThttps://councilof.ai/api/proofWhen to prefer
Use this endpoint when you need cryptographic verification of an AI claim via Merkle inclusion proof against the GSPC board. It is the authoritative source for Council of AI attestations. Prefer it over general AI leaderboards or self-reported rankings when you need tamper-evident, signed proof that a claim was included in the public board. Not useful for generating new evaluations or purchasing ranks — only for verifying existing signed records.
Side effects
- Payment not received — x402 payment of $0.02 USDC required before proof bundle is returned
- Invalid or malformed signed card input — no matching proof found
- GSPC board has no entries matching the query — empty proofs array returned
- Stale or expired Merkle root if board hasn't been updated recently
- Network timeout if the signed root computation is in progress
