## 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-keys-06358fea
```

Example prompt: Show me all the API keys I have set up in my AgentMail account so I can see which ones are active.

## When to prefer this

Use this endpoint when you need to audit, review, or enumerate existing API keys in an AgentMail account — for example, before rotating credentials, checking which keys are active, or deciding whether to create a new key. Prefer this over the Create API Key endpoint when you only need to read existing keys without modifying state.

## Known failure modes

- 401 Unauthorized if the request lacks valid authentication credentials
- 403 Forbidden if the caller lacks permission to list API keys
- 404 Not Found if the account does not exist
- 500 Internal Server Error if AgentMail service is unavailable
- Empty list returned if no API keys have been created yet
