Two endpoints, one API key
Everything the free checker does, callable directly: score a site, then generate the fixes for whatever it finds.
POST /v1/audit
Crawls a URL the way GPTBot or Google-Extended would, scores it across four categories (crawl access, structured data, answer readiness, NAP consistency), and returns evidence for every check.
POST /v1/generate
Generates the fix for whatever the audit found: JSON-LD structured data, an llms.txt file, FAQ content. Anything it can't confirm from the site is flagged, never invented.
