## 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 cron-memoryapi-org-cbd9d079
```

Example prompt: Check AgentCron for any change alerts on my monitored URLs and show me what changed and when.

## When to prefer this

Use this endpoint when you need to programmatically retrieve change alerts for URLs previously registered with AgentCron for monitoring. Ideal for agents that need to react to content changes on external URLs on a scheduled or event-driven basis.

## Known failure modes

- Invalid or missing authentication returns 401 Unauthorized
- No alerts available returns empty list
- Payment not processed (x402) returns 402 Payment Required
- Service unavailable returns 503
- Malformed request returns 400 Bad Request
