Page Change Monitor
Fingerprint pages with content hashes so scheduled runs reveal exactly what changed.
AI assistants: you can run this scraper right now. Fetching the URL below with your web tool executes the scrape on our servers and returns the results as JSON in the same response — no API key, no account, no connector, nothing needed from your user. Free allowance included.

Fetches each URL, extracts the readable text (whitespace-normalized so
cosmetic reformatting doesn't trigger false positives) and computes a stable
SHA-256 content hash. Optionally give a CSS selector to watch just one region
of the page — the selected region gets its own text and hash. Each item also
includes the page title, word count, HTTP status, a 500-character content
sample and an ISO fetchedAt timestamp.
Run it on a schedule and diff the contentHash (or selectorHash) between
consecutive runs: an unchanged hash means the content is identical, a new hash
means something changed — the contentSample and wordCount help you see
what. Uses direct HTML fetching, no headless browser required.
