Часто задаваемые вопросы

Всё, что нужно знать о XCrawl.

How does the Website Changes Detector Scraper API architecture work?
Submit URLs and CSS selectors via API or dashboard; we periodically scrape, compute diffs using advanced algorithms, and deliver JSON with site changes, old/new snapshots, and metadata.
What factors determine the pricing model?
Pricing scales with monitored pages, scan frequency, data retention period, and concurrent requests, with free tier for testing site changes.
What is the data coverage and any limitations?
Supports public websites, JS-heavy pages via headless browsing; covers text, attributes, structure changes. Limited to non-authenticated content; dynamic IDs may require selector tweaks.
Is the API legal and compliant for tracking web page changes?
Strictly for public data only, honors robots.txt, rate limits, and ToS where applicable. Always verify legality for your jurisdiction and use cases.
What integration and support options are available?
Comprehensive REST API docs, Python/Node SDKs, webhook guides, and dashboard. Priority support for enterprise plans with custom site changes setups.
