webscraperapi.ai: The Web Toolkit Your AI Agents Won't Get Blocked On

Detect technologies used by a website including e-commerce platforms, analytics tools (GA4, Google Ads), and tracking pixels (Facebook Pixel, GTM).

Use this to find out what tech stack a website runs — CMS, analytics, frontend frameworks, payment processors, CDN, chat tools, and more. Great for lead qualification and competitive research.

2 credits per request. Add render_js=true for sites that load tech dynamically (+4 credits).

Quick example

curl -G "https://api.webscraperapi.ai/v1/detect_technologies" \
  -H "Authorization: Bearer $WEBSCRAPERAPI_API_KEY" \
  --data-urlencode "url=https://shopify.com" \
  --data-urlencode "output=json"

Use render_js=true for single-page apps where tech is loaded via JavaScript. Without it, you may miss client-side frameworks and analytics tools.
