Core features of the website audit API
Audit summary and issues
The audit_summary endpoint returns the Website Score, crawled pages and issue counts by severity, each compared with the previous crawl. The audit_issues endpoint lists detected issues and filters by category, severity and segment.
Categories include links, redirects, indexability, duplicate content and page speed, so broken links come out as clean rows.

Page level details
The audit_pages endpoint lists crawled URLs with key audit attributes. The page_details and page_content endpoints return deep technical data for one URL, like internal links, images, CSS and JavaScript files.
Use them to check one template or a key landing page without opening the app.

Filter by segment
Pass a segment_id to scope summaries, issues and monitoring to the pages that matter. Every project has All pages and Indexable pages, plus your own segments.
Issues to tickets
Poll new critical issues after each crawl and create tasks in Jira, Asana or your own ticketing tool. Each issue comes with the URLs it affects.
Deploy and migration QA
After a release, compare crawls with site_audit_updates and check key templates with page monitoring. Catch broken titles, canonicals or status codes before clients do.
Page change monitoring
Content updates show unexpected edits, deleted pages and new pages. Send them to Slack or email, so a hacked or broken page is caught fast.
