Website Change Monitor API

Track page and price changes over time: diffs, history, and alerts through simple tracking endpoints.

Part of the DataLeads API suite (Monitoring category). Requests render in a real browser with anti-bot handling and protected-page support built in - no proxies to manage, no infrastructure to run.
