How this service works
Explore the current GSPC measurements, see the published change record, verify signed evidence, and access the supported public feeds.
Output
Returns a JSON attestation card with: the subject identifier, GSPC status (e.g. COMMISSIONED, UNMEASURED), reserve scores, a list of unmeasured axes, the surface slug, and an ed25519 hex signature (or null if unsigned). The card conforms to the councilof.ai card-v0 schema.
Example use cases
Verify AI model safety claim
“Can you pull the Council of AI attestation card for Claude 3 Opus and tell me if it's been measured and what its GSPC status is?”
Check specific axis score for instrument
“Look up the Council of AI GSPC board entry for the subject 'llama-3-70b' on the 'root_inclusion' axis and show me whether it's been measured or is still empty.”
Validate a shared attestation card
“I was sent this card sha — 'abc123def456' — from a vendor claiming their AI is Council of AI certified. Can you verify it against the GSPC board and confirm whether the signature is valid?”
Technical details
Endpoint
GEThttps://councilof.ai/api/request-attestationWhen to prefer
Use this endpoint when you need to programmatically verify or retrieve a signed GSPC attestation for a specific AI model, instrument, or card hash — particularly when you want axis-level detail or a cryptographically signed result. Prefer this over the free CSOAI door endpoint when you need per-subject or per-axis granularity rather than aggregate board totals.
Side effects
- Missing required 'subject' query parameter returns a validation error
- Unknown or unrecognized subject ID returns an empty or null card
- Axis slug not found for subject returns unmeasured status for that axis
- Payment not completed (402) blocks access to the commissioned result
- Card sha does not match any known signed card, returning null signature
