# Delete API Key

`DELETE /keys/{key_id}`

Deletes an API key by its ID. This action is irreversible.

**Requirements:**
- Authentication required via admin API key
- Key must belong to the authenticated user's workspace

**Key Features:**
- Permanently revoke API key access
- Idempotent operation (safe to retry)
- Optional Idempotency-Key header for safe retries

**Important:**
- This action cannot be undone
- Any applications using this key will immediately lose access
- Returns 204 even if the key doesn't exist (idempotent behavior)

**Common Use Cases:**
- Revoke compromised keys
- Clean up unused keys
- Implement key rotation (delete old, create new)
- Offboard team members
