Chrome UX Report (CrUX) is Google's dataset of real-user web experience metrics gathered from Chrome users. It provides performance data for websites and pages, including Core Web Vitals metrics and historical timeseries.
chromeuxreport.googleapis.com exposes one authenticated HTTP API: the Chrome UX Report API, documented on developer.chrome.com and accepting either a Google Cloud API key or a Google OAuth 2.0 access token.

In Google Cloud Console, create or select a project, enable the Chrome UX Report API, then create an API key under APIs & Services → Credentials. Use the key as the key query parameter when calling the API. The CrUX docs' Acquiring and using an API key section links to the same Google Cloud Console flow.
Create OAuth 2.0 client credentials in Google Cloud Console, then run the standard Google OAuth flow to obtain an access token for your project/user. The Chrome UX Report discovery document says requests are authenticated with an OAuth 2.0 token via the oauth_token or access_token query parameter as an alternative to an API key.
