One API Call to Analyze Any Website: Tech Stack, SEO, Contacts and More

I got tired of calling 7 different APIs just to understand a single website. So I built one that does everything in a single call. Historically, getting a complete picture of a website required a "Frankenstein" stack of integrations. You would need one API for tech stack detection (like Wappalyzer), another for SEO metrics, a third for email/contact scraping, a fourth for WHOIS data, and yet another to clean the HTML into Markdown for your LLMs. Managing seven different API keys, seven different billing cycles, and seven different JSON formats is a developer's nightmare. It introduces latency, increases costs, and creates multiple points of failure. Enter the WebSight API . Hosted on the Apify platform, this tool collapses those seven layers into a single, high-performance API call. In this tutorial, we will explore how to use the WebSight API to extract tech stacks, SEO audits, contacts, and AI-ready content in one go.
