# Revoke API key

`DELETE /api/api-keys/{key_id}`

Revokes an API key so it can no longer authenticate. The key remains visible as inactive.

## Path parameters

- `key_id` string, required — ID of the API key to revoke

## Response `200`

Successful Response

- DeletionResponse — Acknowledgment body returned by destructive endpoints (delete / trash / restore / permanently delete / remove-from-album / empty-trash). Carries no fields — the HTTP 200 + empty JSON object is itself the success signal. Exists so MCP tools generated from these endpoints have a real ``outputSchema`` (rather than the null schema FastMCP emits for 204 responses), which ChatGPT's MCP submission tooling requires.

## Other responses

- `401` — Missing, invalid, or expired credentials.
- `403` — The credentials are valid but not authorized for this operation — for example an API key whose action or library scope excludes it, or a credential type this operation does not accept.
- `404` — Not found
- `422` — Validation Error
- `429` — Rate limit exceeded. Retry after the interval in the `Retry-After` header.
