JS Endpoint Extractor

Enter a JavaScript file URL to discover real API endpoints, paths, and parameters embedded in the code. Extracts URLs, relative paths, and AJAX/fetch/WebSocket calls.

Direct URL to a .js file (use your browser's network tab to find JS bundles)

Why JS Endpoint Extraction?

Modern web applications bundle JavaScript files that often contain hardcoded API endpoints, authentication tokens, and internal route paths. Extracting these endpoints reveals the full API surface, including undocumented or deprecated endpoints that may have security vulnerabilities. This JS endpoint extractor actually fetches the JavaScript file and extracts URLs, API routes, WebSocket endpoints, and fetch/AJAX calls using pattern matching.
