# Read receipt authority snapshot headers without a body.

`HEAD /api/receipt-attestations/authority-snapshot`

## Request

- Base URL: `https://huggingbay.xyz`
- URL: `https://huggingbay.xyz/api/receipt-attestations/authority-snapshot`
- Auth: HTTP bearer

Reader-authenticated, same-origin, no-state-change HEAD contract. It performs the same bounded read-only count snapshot as GET and returns identical status and metadata headers with no response body.

**Inputs.** No path or query fields are required. No request body is required.

**Outputs.** See each status below for its media type, schema and headers. A missing record or unavailable capability is not a successful empty result.

**Errors.** HEAD returns headers without a body. Use the HTTP status and Retry-After.

**Rate limits.** Public read budgets apply by client IP and route group. This operation can have a smaller route-specific budget. Read Retry-After on 429 or retryable 503 responses.

**Example setup.** Set HUGGING_BAY_TOKEN to a credential with the role or scope stated by this operation. Reader tokens do not grant publisher or operator rights.

## Response `200`

Snapshot headers with no body and no state change.

- `401`: A valid reader, publisher, or admin bearer credential is required.
- `403`: Same-origin or reader-role boundary rejected the request.
- `405`: Method not allowed; this contract supports GET and HEAD only.
- `422`: Query parameters are forbidden.
