Hi everyone,

Today we released the initial version of the Chrome UX Report API, a fast, free, and RESTful API for monitoring real-user experiences of websites and pages!

To give it a try, grab yourself an API key and check out the developer guide.

The features of the API include:

fast and free usage with a generous quota
coverage of all Core Web Vitals' good, needs improvement, and poor buckets
75th percentiles
URL and origin support
desktop/phone/tablet breakdowns

If you have any feedback or issues with the API, please let us know in the discussion forum or reach us on Twitter at @ChromeUXReport. We'd love to hear what you think!
