It is a single-URL technical SEO audit. GET /v1/on_page/page?url= returns title, meta, headings, on-page score, checks such as HTTPS and canonical, and page timing as unified JSON on one x-api-key. ### Does it crawl a whole site or one URL? One URL per call. It is an instant page audit, not a site-wide crawl. Pass the absolute https URL you want scored. ### What does the on-page audit return? Title and description, heading counts, on-page score, boolean checks (HTTPS, canonical, broken links, 4xx/5xx), and page timing such as time to interactive. The payload is Analytics passthrough because the audit shape is heterogeneous. ### How much does the on-page audit API cost? GET /v1/on_page/page costs 1 credit per request. New accounts get 100 free credits with no credit card. ### Do I need to enable JavaScript for the audit? No. JavaScript is off by default. Set enable_javascript=true when the page's title or canonical is injected client-side. ### Is this a Lighthouse report? No. It is an on-page SEO audit (meta, headings, checks, timing), not a Lighthouse lab report. Use it to inspect one public URL quickly. ## Pricing - Standard endpoints: 1 credit per call - Advanced endpoints: 5 credits per call - Premium endpoints: 10 credits per call - 100 free credits on signup, no credit card required.
