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
A JSON object containing the full corrections ledger slice with: total correction entry count (n), ledger state (INDEXED), as-of date, raw ledger rows (verbatim artifact bytes), source file references, settlement provenance (payer address, network, transaction hash), and a signed attestation block with ed25519 signature and SHA-256 hashes conforming to the csoai.population-door/0.1 schema.
Example use cases
Auditing AI benchmark correction history
“Show me the full corrections ledger from Council of AI — I want to see every published correction to their AI measurement results, including who paid for the lookup and the cryptographic attestation so I can verify nothing has been altered.”
Monitoring AI evaluation integrity
“Check the Council of AI corrections ledger right now and tell me how many correction entries exist and what the current state is — I need to confirm no new corrections have been issued to the benchmark cards we referenced last week.”
Verifying signed correction evidence
“Fetch the corrections record from Council of AI and give me the ed25519 signature and SHA-256 hash so my compliance team can independently verify the corrections data is authentic and hasn't been modified.”
Technical details
Endpoint
GEThttps://councilof.ai/api/pop/corrections?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need cryptographically verifiable, signed evidence of corrections to AI measurement results from Council of AI — specifically when auditability and tamper-evidence matter. Prefer this over generic web scraping of the corrections ledger when you need machine-readable structured data with attestation. Ideal for compliance, audit trails, or agent workflows that must verify no benchmark results have been silently altered.
Side effects
- Payment not received or insufficient USDC — returns 402 Payment Required
- Invalid HTTP method (non-GET/HEAD/DELETE) — request rejected by schema validation
- Ledger temporarily unavailable or indexing in progress — state may not be INDEXED
- Attestation signature may be null if the slice is unsigned (labelled as supporting run only)
- Network or settlement verification failure — transaction hash may be null in settle block
