Scans a URL for WCAG 2.1 accessibility violations using DOM analysis (axe-core) and visual AI (Claude Vision). Returns structured violation data and a scan_id for use with other tools.

Takes scan results and generates specific code fixes for each accessibility violation. Returns ready-to-apply code patches and a copy-paste summary for Claude Code or Replit Agent.

Re-scans a URL after fixes have been applied and compares results against the original scan. Returns which violations were resolved, which persist, and any new issues introduced.

Generates a complete VPAT 2.5 EN 301 549 accessibility conformance report based on scan results. Returns structured JSON and a downloadable PDF (base64-encoded). Covers all EN 301 549 clauses; non-web clauses are marked Not Evaluated with professional notes.
