Define a meaningful change
Use exact or semantic detection for the target and workflow you need.
Deliver the update
Send signed change events to your webhook and inspect delivery history.

Set the schedule.
Act on the change.

A few things
to know.

More details in the API documentation.

What can I monitor?

Monitors support pages, sitemaps, and supported extracted data. Choose the target and detection mode that match the information your application needs to keep current.

Can I compare meaning rather than exact text?

Semantic detection is available for supported target types. Exact detection is useful when the precise content change matters.

How do I choose the schedule?

Set an interval schedule when you create the monitor. You can also update its schedule or trigger an additional run.

How are changes delivered?

Configure a webhook for change events. Verify the signature in your application and use delivery history to inspect attempts.
