How to check Core Web Vitals for 1,000 URLs in Python (PageSpeed Insights API, CrUX field data, quotas and retries)
A ~100-line Python script that runs PageSpeed Insights for a list of URLs with concurrency, retries and quota handling, separates lab data from real-user CrUX data (LCP, INP, CLS) and writes one CSV. Tested in October 2026.
