## 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 predator-ubuntu-scheduled-url-wallet-monitor-f757d603 -d '<json body>'
```

Example prompt: Watch https://example.com/pricing for any content changes every 30 minutes for the next 30 days — set it up as a scheduled monitor and give me a job ID I can poll for results.

## When to prefer this

Choose this endpoint when an AI agent needs to monitor an external URL or crypto wallet for changes/payments without running its own cron infrastructure. It is ideal for agents that need lightweight, cloud-managed scheduled checks with a polling pattern to retrieve results asynchronously. It is specifically suited for x402-native workflows where paying per-call in USDC is acceptable.

## Known failure modes

- Invalid or unreachable target URL returns an error at schedule creation
- Wallet address format not recognized causes rejection
- check_interval_minutes outside the 5–1440 range is rejected with a validation error
- Payment of $0.03 USDC not received results in 402 rejection
- Polling endpoint returns no results yet if no changes/payments detected
- 30-day window expires and further polling returns no new data

## How this service works

Scheduled execution for agents without cron: we check a URL for changes or a wallet for new USDC payments on schedule for 30 days, you poll for results

## Output

Returns a scheduled job identifier that the caller can use to poll for results. Results include change detection events (diff or new content detected on the target URL) or payment detection events (new USDC transactions to the wallet), timestamped per interval check over the 30-day monitoring window.
