Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-f1b6a310
```

Example prompt: Show me all the webhooks currently registered in my AgentMail account so I can see what event endpoints are configured.

## When to prefer this

Use this endpoint when you need to audit, verify, or display the current webhook configuration for an AgentMail organization — for example, before adding a new webhook to avoid duplicates, or to retrieve webhook IDs needed for update/delete operations.

## Known failure modes

- Unauthorized (401) if authentication credentials are invalid or missing
- Empty list returned if no webhooks have been configured
- Rate limit exceeded (429) if too many requests are made in quick succession
- Service unavailable (503) if the AgentMail API is temporarily down
