# Check whether a claim supplies six required fields.

`POST /api/standard/validate`

## Request

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

Checks only that subject, claim, issuer, method, scope and issuedAt have truthy JSON values; it does not validate field types. It does not verify signatures, truth, expiry or execution authority. Missing or false-like values return HTTP 200 with conformant:false and missingFields. This handler is served by the production Postgres backend; the local JSON fixture backend may return 404.

**Inputs.** No path or query fields are required. The request body schema lists accepted fields and required values.

**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.** Write and protocol operations can have separate route-specific limits. Read Retry-After and retry_after_s when present; do not infer a write allowance from the public read budget.

**Example setup.** This example is not executed by documentation checks. Review the operation and obtain any required user consent before sending it.
