What is a web intelligence API?

A web intelligence API gives you structured data about any website — who links to it, what technology it uses, and what's on its pages. Instead of crawling the web yourself or paying multiple vendors, you make one API call and get the complete picture.

Who uses this?

SEO teams use link intelligence to audit backlink profiles, find link building opportunities, and monitor competitors. The same data that powers premium SEO tools, accessible via API at a fraction of the cost.

Product teams use technology intelligence to understand market adoption. How many sites use React? Which companies still run WordPress? Query the data and find out in seconds.

Data teams use page intelligence to enrich datasets. Titles, descriptions, languages, and server information for any URL — without running a crawler.

How does the data work?

We continuously index the web, extracting links, metadata, and technology signatures from every page we process. The data is stored in a high-performance columnar database optimized for fast lookups across billions of records. When you query a domain, you get results in seconds — not minutes.
