The Shipwork API
Every free check is a JSON endpoint: send a site, get findings with the page and the fix for each. Built for scripts, dashboards and AI agents. No key and no signup.
free_limit.POST /api/audit
Audit a site. Crawls a set of pages from outside the network and runs every check that applies (indexing, robots.txt, sitemap, canonicals, structured data, internal links, AI crawler access and more). Returns findings grouped by check, each with the page and the fix.
curl -X POST https://shipwork.io/api/audit -H "content-type: application/json" -d '{"url":"example.com"}'POST /api/score
Score a site 0-100. Runs the audit and returns a 0-100 health score, a letter grade, the top fixes and a shareable snapshot id.
curl -X POST https://shipwork.io/api/score -H "content-type: application/json" -d '{"url":"example.com"}'POST /api/bulk-status
Status codes for a list of URLs. For each URL: status code, every redirect hop, the final URL, and whether the final page is noindex or canonicalised elsewhere. Up to 25 URLs free.
curl -X POST https://shipwork.io/api/bulk-status -H "content-type: application/json" -d '{"urls":"https://example.com/\nhttps://example.com/old"}'POST /api/sitemap-generator
Generate an XML sitemap. Crawls a site from its home page and returns sitemap.xml of its indexable pages, with every excluded page and the reason.
