Frequently asked questions
How do I catch breaking API changes before they hit production?
Paste the API documentation page or a response endpoint you depend on. We check it on a schedule and compare versions. AI reviews the content and alerts you when a breaking change appears, such as a renamed or removed field, a changed response type, a deprecated endpoint, or a new required parameter.
How fast will I be alerted about a breaking change?
As fast as you need. Choose instant alerts to hear the moment a breaking change is detected, or a daily or weekly digest that groups changes into one summary. Instant is best for production dependencies, so you can update your integration before the change breaks anything downstream.
Does it work on any API and is it free?
It is free to start and works on any public API documentation page or response URL. Paste the link, set the check frequency, and pick instant or digest alerts. AI relevance filtering skips version banners, ads, and cosmetic edits, so you only hear about the changes that actually affect your code.
