URL change detection and web monitoring: did this page change since the last check? (urlwatch, page monitor, content change)
https://merchandise-threshold-crucial-lift.trycloudflare.com/urlwatch-402Overview
Tell whether a public page changed since the last check. Returns change_kind (baseline / changed / unchanged / became_error / recovered), the sha256 of the page text before and after, and the added and removed lines. The fingerprint is over normalised page text, not raw HTML, so render nonces and timestamps do not register as a change.
