## Other responses

- `400`: Error response. `code` is the machine-readable reason — see the [error reference](/api/errors) for the full catalog and remediation per code.
- `401`: Error response. `code` is the machine-readable reason — see the [error reference](/api/errors) for the full catalog and remediation per code.
- `403`: Error response. `code` is the machine-readable reason — see the [error reference](/api/errors) for the full catalog and remediation per code.

- `429`: Rate limited. Usually the per-API-key REST limit (600 requests/minute); on Google-backed endpoints it can also relay an upstream Google rate limit. `Retry-After` (seconds) is present when the limit was applied by Searchable's own rate limiter; it may be absent when an upstream provider rate-limits.
- `504`: Error response. `code` is the machine-readable reason — see the [error reference](/api/errors) for the full catalog and remediation per code.
