Audits in OnPage Lighthouse API

 
The OnPage Lighthouse API is based on Google’s open-source Lighthouse project and provides data on the quality of web pages.

Lighthouse Audits are objects containing the results of the page quality tests run by Lighthouse. This endpoint will provide you with a list of titles available for Lighthouse Audits. You can obtain the results of certain audits by specifying the corresponding titles in your Task POST requests.

OnPage Lighthouse API is based on an open-source Lighthouse project. You can find the official documentation here.
