# Revoke an API key

`DELETE /api-keys/{key_id}`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/api-keys/{key_id}`
- Auth: HTTP bearer

Authorization: `key_id` is matched together with the authenticated caller's user id, so a key owned by another user is invisible (404) and no one else's personal key can be revoked.

## Path parameters

- `key_id` string, required

## Response `200`

Key revoked

- object
  - `revoked` boolean
  - `key_id` string

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Forbidden
- `404`: Resource not found
- `429`: Rate-limit exceeded. The global per-IP limiter (100 requests/minute, applied to every `/v1/*` route) rejected this request. Back off until the window resets — `Retry-After` carries the cooldown in seconds and `X-RateLimit-Reset` the absolute reset time.
- `500`: Server error — request was well-formed but the server failed to fulfill it. Typically a downstream dependency (DB / RPC / external API) returned an unexpected error.
