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 object containing the SWIFT population slice with: slice ID ('swift'), row count (n), verbatim population rows, as-of date, indexing state, unit description, schema version, settlement info (payer, network, transaction), source file reference, and a full attestation object including schema URL, SHA-256 hash, payload kind, surface label, and optional Ed25519 signature.
Example use cases
Verify SWIFT bank census integrity
“Fetch the Council of AI SWIFT population slice and check if it's cryptographically signed — I want to confirm the SHA-256 hash and Ed25519 signature are present so I know the data hasn't been tampered with.”
Audit AI benchmark population coverage
“Get the SWIFT slice from Council of AI so I can see how many sourced bank rows are in the measurement population and what date the snapshot was taken from.”
Retrieve settlement and attestation for compliance
“Pull the Council of AI SWIFT population slice for me — I need the full attestation payload including the payer address, network, and transaction hash from the settle field for our compliance records.”
Technical details
Endpoint
GEThttps://councilof.ai/api/pop/swift?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically attested, independently verifiable SWIFT bank population data with a signed measurement card. Prefer it over raw census files when auditability, non-repudiation (Ed25519 signature), and chain-of-custody (settlement info) are required. Especially useful for AI evaluation pipelines needing frozen, reproducible population snapshots tied to a specific as-of date.
Side effects
- Payment not received — returns 402 if USDC payment not included
- Invalid HTTP method — only GET/HEAD/DELETE accepted per schema enum
- Attestation signature may be null if run is unsigned (labelled as supporting, not issued)
- Data not yet indexed — state field may reflect non-INDEXED status
- Source file unavailable — /interop/swift-census.json missing or stale
- Network/facilitator connectivity failure returning 5xx
