POSThttps://seolyticize.com/api/v1/tools/page_lab

Lighthouse performance, SEO, accessibility and best-practices scores for one address, from PageSpeed Insights. Answers 'what is slow or wrong on this page' with a reproducible lab run, including for pages too quiet for field data. This is not what real visitors experienced — use page_vitals for that, and say which is which when reporting both. There is no interaction metric here: a synthetic run interacts with nothing.
