Clients can use this to detect degraded data. ## Other responses - `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401. - `422` — Validation Error - `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window. - `503` — Upstream source is temporarily unavailable. Retry after a short delay. --- [API](https://skmtc.net/sugra/apis/sugra-api.md) · [All operations](https://skmtc.net/sugra/apis/sugra-api/llms.txt) · [OpenAPI document](https://skmtc-service-staging.skmtc.workers.dev/v1/apis/sugra/sugra-api/versions/d3e3d9c28132/schema)
