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.
Example use cases
E-commerce price drop alert
“Keep an eye on https://store.example.com/product/widget and check every 60 minutes for the next 30 days — let me know as soon as the page content changes so I can catch a price drop.”
Wallet payment listener for invoicing
“Watch the wallet address 0xAbC123... for any new incoming USDC payments, checking every 10 minutes, so I know when a client has paid their invoice — set that up for 30 days and give me a poll ID.”
Competitor landing page tracker
“Schedule a monitor on https://competitor.com/launch every 5 minutes and alert me when the content changes — I want to catch the moment they announce their new product.”
Technical details
Endpoint
POSThttps://predator-ubuntu.taild9a745.ts.net/v1/schedule?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
