ZXH API DISCOVERER maps publicly exposed API endpoints, web service URLs and JavaScript-connected data layers from a target page — directly from your browser.
A focused browser-side reconnaissance interface for identifying API-shaped resources visible through public HTML and JavaScript assets.
The discovery engine looks beyond the obvious page source, following linked JavaScript and recognizing common API infrastructure patterns.
Detect API-looking URLs, REST paths, GraphQL references, versioned routes, query endpoints and common cloud service URLs.
Scan the target document for visible absolute and relative endpoint candidates.
Follow linked JavaScript assets and inspect their contents for API references.
Recognize Vercel, Workers, Firebase, Supabase, AWS and other common infrastructure patterns.
Copy discovered endpoints or attempt a GET request and inspect the returned response directly inside the discovery workspace.
Enter a publicly accessible website URL. The browser requests the page and starts the discovery process.
HTML is inspected for absolute URLs, relative API paths and recognizable service patterns.
Linked JavaScript resources are inspected to discover endpoints that are not directly visible in the HTML.
Results are ranked, displayed and available for copying or optional GET testing.
Enter a public URL below. Results depend on browser CORS policy and what the target exposes to clients.
ZXH API DISCOVERER is designed for public-facing web architecture research, debugging and authorized testing. It does not claim to defeat authentication, private endpoints or access controls.
Put a public URL into the engine and inspect the API-shaped architecture exposed through its client-side resources.
