PageSpeed Lighthouse Audit, Core Web Vitals & Technical SEO API ($1.00 / 1,000 URLs)

Audit thousands of websites or prospect domains in bulk for response time (TTFB), technical SEO score (0–100), meta title/description optimization, H1/H2 structure, missing image alt attributes, Schema.org JSON-LD, robots.txt, and sitemap.xml at just $1.00 per 1,000 URLs — 100% browserless in 256 MB RAM.

Built for SEO Agencies, Web Design & CRO Agencies, Clay.com Cold Email Personalization, n8n, Make, and MCP AI Agents.

Why SEO Agencies & Outbound Teams Use This API

Instant Cold-Email Personalization (seoIssues): Automatically generates concrete technical flaws for every prospect website (e.g., "Missing meta description", "Multiple H1 tags", "14 images missing alt attributes", "No Schema.org JSON-LD found", "Slow TTFB > 2500ms").
Sub-Second Chrome-Fingerprinted Execution: Uses impit (Chrome TLS fingerprint) in 256 MB RAM without getting blocked by Cloudflare or waiting 25 seconds per URL for headless Chromium.

Input Example

{
  "urls": [
    "https://linear.app",
    "https://allbirds.com"
  ],
  "checkRobotsAndSitemap": true,
  "includeMcpMarkdown": true
