To check if a single origin or URL is in CrUX, the PSI web UI is the quickest way.

If you have a batch of known URLs you can use a script similar to the PSI Monitoring code to test them all against the PSI API.

If you have a batch of known origins, you could write a query against the BigQuery dataset similar to SELECT DISTINCT origin FROM chrome-ux-report... WHERE origin IN (a,b,c).

To get all unknown URLs for a given origin, there is no equivalent queryable dataset. The only scenario I can imagine this info being provided is if the requester can verify permission from the webmaster.
