# audience-type-unknown

`https://ckrets.ai/problems/audience-type-unknown` is a problem type of the ckrets.ai API (RFC 9457: the body is
`application/problem+json` with `type`, `title`, `status` and `detail`; every problem from `/v1` also carries `requestId`).

| Status | Also in the answer | What to do |
|---|---|---|
| 400 | - | the audience's `type` is not one this version takes: it takes `key`, `oidc` and `publicKey`; `httpsig` is planned with the signed-agent tier, and an object or array with no `type` (`{}`, `[]`) gets this answer too. Nothing was made. Use one of the three types, or leave `audience` out for a bearer link |

Every type, with its retry rule and headers: [limits.md, "Errors, retries and headers"](/limits.md#errors-retries-and-headers).
