How this service works
We measure how AI systems behave against frozen, published tests and publish checkable evidence. Issued measurement cards are signed; unsigned supporting runs are labelled. Read the live board and corrections ledger.
Output
Returns a JSON feed with schema 'csoai.eunomia-data/0.2' containing four block types: root (the public signed root), signals, card_index, and first_fine_watch. Empty cells in the board are returned empty. The response reflects the live GSPC board state and can confirm or deny the validity of a submitted signed card.
Example use cases
Verify a suspicious AI performance claim
“I received a signed card claiming an AI system scored highly on GSPC — can you verify it against the Council of AI's Eunomia feed and tell me if it's legitimate or fabricated?”
Read current GSPC board state
“Pull up the latest GSPC board from the Council of AI and show me the current blocks, signals, and card index — I want to see the live state of AI performance rankings.”
Audit AI measurement integrity
“I need to confirm that this AI evaluation result wasn't just sold or made up — check it against the Council of AI's signed root and tell me what the Eunomia data says about its legitimacy.”
Technical details
Endpoint
GEThttps://councilof.ai/api/eunomia-data?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify a specific signed AI measurement card or read the live GSPC board state from the Council of AI's authoritative Eunomia feed. Prefer this over the free CSOAI door endpoint when you need the full data feed including card_index and first_fine_watch entries, not just board totals. Choose this when cryptographic verification of an AI claim or rank is required and you need the complete signed data structure.
Side effects
- Payment not received — x402 payment of 0.02 USDC required per call or request is rejected
- Invalid or malformed signed card input — card fails verification and returns empty or error block
- GSPC board temporarily unavailable — empty blocks returned with no data
- Network timeout or service unavailability — no response or partial feed
- Unsupported schema version — client expects different schema than csoai.eunomia-data/0.2
