Website technology detection API

Fetches a page and fingerprints its technologies (CMS, frameworks, ecommerce, analytics, CDN, JS libraries, server) from response headers + HTML signatures using a built-in ruleset, returning each detection with the evidence that matched. The value-add: messy headers/markup become a clean categorized technology list. Answers 'what is this site built with', 'does this use WordPress/Shopify', 'what analytics does this site run', 'detect the framework behind this URL'.
