SEO Score API

SEO Score API — 82-Check SEO Audits in One API Call

Score any URL in under 2 seconds. SEO Score API runs 82 checks across on-page SEO, technical SEO, performance, accessibility, AI readability, and GEO (Generative Engine Optimization) — returning a 0–100 score, letter grade, and prioritized fix list as clean JSON.

Built for developers and agencies who want SEO intelligence in code, not a dashboard. Plug it into CI/CD pipelines, SaaS products, client reporting tools, or AI agents. SDKs available for Python and Node.js. Official GitHub Action and n8n node included.

Paid plans unlock SXO, AEO, and AIO scoring — measuring search experience, featured snippet eligibility, and LLM citation readiness alongside traditional SEO.

Free tier included. No credit card required. Get an API key in 30 seconds.
