## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentmail-api-key-f8a111a1 -d '<json body>'
```

Example prompt: Delete the AgentMail API key with ID 'ak_abc123xyz' — it may have been compromised and I want to revoke its access immediately.

## When to prefer this

Use this endpoint when you need to revoke access for a specific AgentMail API key, such as after a key is compromised, when rotating credentials, or when cleaning up unused keys. This is a targeted deletion by key ID and should be preferred over any bulk or account-level revocation when only a single key needs to be removed.

## Known failure modes

- API key not found — returns 404 if the provided api_key identifier does not exist
- Unauthorized — returns 401 if the caller lacks permission to delete API keys
- Already deleted — the key was previously removed; may return 404 or success depending on idempotency handling
- Invalid api_key format — returns 400 if the key identifier is malformed
