Frequently asked questions
How do I receive page changes as a webhook?
Paste the page URL and provide your endpoint. We check the page on a schedule and POST a webhook whenever a meaningful change is detected, including the diff so your code sees exactly what changed. This demo mirrors what the API does, so you can validate your handler before wiring up the full integration.
What triggers the webhook and what gets ignored?
AI relevance filtering compares each check to the previous one and fires only on genuine updates, such as a new changelog entry, edited documentation, or a pricing change. Ads, cookie banners, navigation, and unrelated sidebars are ignored, so your endpoint is not flooded with events for cosmetic page churn.
How fast are webhooks delivered?
You can receive webhooks instantly as soon as a change is detected, which suits changelogs, status pages, and docs. If you would rather batch events, you can switch to a daily or weekly digest instead. It is free to start and works on any public page by pasting a URL.
