  - `angleId` string, required: The angle this concept belongs to.
  - `name` string, required: Your own name for the concept.
  - `attributes` string[]: What characterises this way of making the claim: ids from *Get the creative vocabulary* (`conceptAttributes`).

## Response `200`

OK. The result is in `data`. List responses also carry `meta` with `nextCursor` and `total`.

- SuccessEnvelope: The shape of every successful response.
  - `data` unknown, required
  - `meta` object: Present on list responses.
    - `nextCursor` union: Pass as `cursor` to get the next page. `null` on the last page.
      - string

    - `total` integer: Number of items in this page.

## Other responses

- `201`: Created. The new resource is in `data`.
- `400`: The request is malformed or fails validation. `error.code` is `VALIDATION_ERROR` (with `details.issues[]` naming each field), `INVALID_REQUEST` (the body is not valid JSON or has the wrong shape), or one of the specific codes listed in this operation's description.
- `401`: The bearer token is missing, invalid, expired or revoked (`INVALID_TOKEN`).
- `403`: The token lacks the scope this operation needs (`INSUFFICIENT_SCOPE`), the plan is read-only (`READ_ONLY_MODE`), or the caller is not a member of the Space named in `X-Space-Id` (`NOT_A_MEMBER`).
- `404`: No such resource in the active Space (`NOT_FOUND`), or `X-Space-Id` names a Space that does not exist (`SPACE_NOT_FOUND`).
- `409`: The request conflicts with the current state, for example a delete blocked by dependents or a sync already running. This operation's description names the `error.code` values it can return.
- `429`: Too many requests (`RATE_LIMITED`). Wait for the number of seconds in the `Retry-After` header, then retry.
