Last updated October 2026Maintained by the SocialCrawl team

Contact us
How do I audit a URL with the on-page API?
GET /v1/on_page/page?url=https://example.com with your x-api-key. The response is one Analytics object with score, checks, and meta.
What URL format does the on-page API accept?
An absolute URL including https://. Relative paths and missing schemes are rejected before the upstream call.
Does the on-page API execute JavaScript?
Not by default. Pass enable_javascript=true when the page injects title or canonical in the browser.
How much does GET /v1/on_page/page cost?
1 credit per request. Cache hits on the same URL cost 0 credits.
Can I crawl a whole domain with this endpoint?
No. Each call audits one URL. For site-wide crawls use a dedicated crawler, not this instant page audit.
