How to Turn Any URL into Clean Markdown for AI Agents & Run Instant SEO Audits (WebPulse API)

A developer built WebPulse AI & SEO Suite, a 5-in-1 web extraction API that converts raw URLs into token-optimized Markdown for LLM and RAG pipelines, runs a 25-checkpoint technical SEO audit in under 150ms, and extracts B2B contact data. The API is available through a free web playground and on RapidAPI with a free tier of 50 requests per month.

If you are building AI agents, RAG Retrieval-Augmented Generation pipelines, or automated scraping workflows, you already know the painful truth: raw web HTML is an absolute token burner. Feeding a full raw webpage into GPT-4, Claude, or Gemini wastes up to 80% of your context window on navigation bars, cookie banners, tracking scripts, and inline SVGs. To solve this, I built WebPulse AI & SEO Suite API: a lightweight, ultra-fast 5-in-1 web extraction API that converts noisy URLs into clean, token-optimized Markdown, extracts rich metadata, audits technical SEO, and discovers B2B contact info in milliseconds. Here is how it works and how you can test it for free today. When you fetch a typical blog post or documentation page: Sending raw HTML to your LLM costs real money, slows down responses, and degrades reasoning accuracy. With the /api/v1/markdown endpoint, WebPulse strips away all boilerplate and returns: Quick Python Example: import requests url = " https://webpulse-ai-markdown-seo-audit-and-contacts.p.rapidapi.com/api/v1/markdown https://webpulse-ai-markdown-seo-audit-and-contacts.p.rapidapi.com/api/v1/markdown " querystring = {"url": " https://stripe.com" https://stripe.com%22 } headers = { "x-rapidapi-key": "YOUR RAPIDAPI KEY", "x-rapidapi-host": "webpulse-ai-markdown-seo-audit-and-contacts.p.rapidapi.com" } response = requests.get url, headers=headers, params=querystring data = response.json print f"Token savings: {data 'data' 'llm token savings percent' }%" print f"Clean Markdown sample:\n{data 'data' 'markdown' :300 }..." Most SEO tools are heavy, expensive, or require full browser emulation. The /api/v1/seo-audit endpoint runs a 25-checkpoint audit directly at the HTTP and DOM level in under 150ms: Perfect for agencies offering automated client onboarding reports or developers building automated website monitors. Need to enrich company profiles automatically? The /api/v1/contacts endpoint crawls the target page and detects: You can test WebPulse immediately in two ways: Interactive Web Playground No login required : Try live URLs directly in your browser: 👉 https://webpulseapi.vercel.app https://webpulseapi.vercel.app RapidAPI Marketplace 50 Free Requests / Month : Subscribe to the Free Tier $0/month to get your API key: 👉 https://rapidapi.com/Juanamigazo/api/webpulse-ai-markdown-seo-audit-and-contacts https://rapidapi.com/Juanamigazo/api/webpulse-ai-markdown-seo-audit-and-contacts Whether you are chaining nodes in n8n / Make / Zapier, fine-tuning local LLMs, or aggregating market intelligence, WebPulse is built to be fast, reliable, and cost-effective.
