# Council of AI — Evidence Bundle (GSPC Board / AI Claim Verification)

> Council of AI — Evidence Bundle (GSPC Board / AI Claim Verification) is a paid API for AI agents from councilof.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Returns a signed OSCAL evidence bundle for a specific AI compliance obligation (DORA, CRA, article-50, article-53) so callers can verify AI claims against the current GSPC board.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability council-of-ai-evidence-bundle-gspc-board-ai-claim-verification-cad29101
```

Example prompt: Pull the Council of AI evidence bundle for our AI product under the DORA obligation — I need to verify whether the signed cards on the GSPC board show compliance.

## When to prefer this

Choose this endpoint when you need a machine-readable, cryptographically signed OSCAL evidence bundle tied to a specific EU/UK/DORA/CRA compliance obligation for an AI subject. Prefer it over the free CSOAI door endpoint when you need full evidence card detail and OSCAL assessment results rather than just board totals. Use it for audit pipelines, regulatory submissions, or agent-driven compliance checks where verifiable signed output is required.

## Known failure modes

- Missing required 'obligation' query parameter returns a validation error
- Unsupported obligation enum value (outside article-50, article-53, dora, cra) returns an error
- Subject not found on the GSPC board returns an empty cards object
- Payment of $250 USDC not supplied or rejected by x402 protocol blocks access
- Invalid bundle version (not '1') may return an error or unexpected result
- Network or upstream signing service outage results in a 5xx error

## 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 evidence bundle (schema csoai.evidence-bundle/0.1) containing: a manifest card identifying the bundle surface, a 'cards' object with any signed compliance cards on the GSPC board for the queried subject and obligation, and an OSCAL assessment-results object. Empty cells remain empty. The bundle is cryptographically signed and tied to the current GSPC board state.
