Web Metadata & Contact Extractor API
(<200ms) API to extract SEO metadata, emails & social links
An enterprise-grade, ultra-fast REST API to extract OpenGraph SEO metadata, public contact emails, social profiles, and CMS/framework tech stack (40+ signatures) from any URL in <200ms. v4.1.0 adds a 14-point SEO audit, graded security headers audit, e-commerce product parsing with multi-source conflict detection, and an AI/LLM-ready Markdown reader. Free tier: 500 requests/month!
I built and fine-tuned this high-performance Web Metadata & Contact Extractor API in partnership with Gemini AI (Antigravity).
We optimized the entire backend stack using C-based HTML parsing (selectolax), HTTP/2 streaming limits (256KB), and in-memory TTL caching to drop execution times from 23+ seconds down to under 200ms!
In our latest v2.6.0 update, we just added some massive features: 🛍️ E-Commerce Parser: Extracts product prices, currency, brand & reviews from Schema.org JSON-LD. 🌐 Advanced SEO & i18n: Full extraction of hreflang tags, robots meta directives, and extended OpenGraph data. 🧠 Adaptive SPA Buffer: Automatically detects React, Next.js, or Astro sites and dynamically expands the stream to extract full SSR content. 🤖 AI Markdown Reader: Converts web articles into clean Markdown for ChatGPT, Claude, and RAG pipelines.
I opened a free tier of 100 requests/month on RapidAPI so developers and makers can easily integrate link previews, lead enrichment, or tech stack detection into their projects.
Would love to hear your thoughts, feedback, or feature requests! 🙌
