Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-batch-receipts-reader-gspc-board-12dd6901
```

Example prompt: Pull the Council of AI GSPC board receipts from January 1 2025 to January 31 2025 and tell me how many claims were recorded and what the batch hash is — use preview mode to keep it free.

## When to prefer this

Use this endpoint when you need to audit, verify, or monitor a time-bounded set of AI claim receipts from the GSPC board. Use the free preview mode (preview=1) when you only need the count and hash for integrity checks without paying per-call. Prefer this over the free CSOAI door endpoint when you need the actual receipt leaf data or Merkle roots within a specific time window rather than just live board totals.

## Known failure modes

- Missing required 'from' query parameter returns a 400 error
- Invalid ISO-8601 datetime format for 'from' or 'to' causes a parse error
- Payment not provided or invalid results in 402 Payment Required (except preview mode which is free)
- 'to' before 'from' may return an empty batch or error
- Batch cap of 200 items means large windows may be truncated

Explore the current GSPC measurements, see the published change record, verify signed evidence, and access the supported public feeds.

## Output

Returns a JSON object with a 'batch' containing: item count, capped list of receipt leaves, Merkle roots, and the time window. Also includes a batch-level SHA-256 hash and a manifest card with an optional ed25519 signature. In preview mode, only count, time span, and hash are returned without leaf data.
