# Read the evidence claim standard and its reference endpoints.

`GET /api/standard`

## Request

- Base URL: `https://huggingbay.xyz`
- URL: `https://huggingbay.xyz/api/standard`
- Auth: none required

The standard names evidence fields and principles. Reading it does not verify a claim or grant permission to execute an artifact. This handler is served by the production Postgres backend; the local JSON fixture backend may return 404.

**Inputs.** Path, query and header fields are listed below. 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.** API JSON failures use the documented response schema. Read code, message and next; retry only when the response allows it. Auth, invalid input and missing records need a caller change.

**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.
