How this service works
Register a URL to monitor for changes. AgentCron polls it on your interval and creates alerts when the response changes.
Output
A confirmation that the URL has been registered for monitoring, likely including a watch/monitor ID, the registered URL, and the polling interval that was set. This ID can then be used to retrieve alerts when changes are detected.
Example use cases
Example prompt
“Keep an eye on https://status.example.com and alert me whenever the response changes — check it every 5 minutes.”
Technical details
Endpoint
GEThttps://cron.memoryapi.org/x402/cron/watchWhen to prefer
Use this endpoint when you need to proactively detect changes to a remote URL on a recurring schedule without building your own polling infrastructure. Ideal for monitoring API responses, status pages, data feeds, or any web resource where change detection matters to downstream workflows.
Side effects
- Invalid or unreachable URL returns an error
- Unsupported polling interval format causes rejection
- Missing required URL parameter returns 400 error
- Payment failure via x402 protocol prevents registration
- Duplicate registration may return conflict or existing monitor ID
