API Request Client
Send, test, and format REST API requests locally in your browser. Configure endpoints, headers, payloads, and analyze status codes.
About API Endpoints & CORS Restrictions
An API (Application Programming Interface) request testing client allows developers to trigger HTTP requests to inspect responses, payload models, and headers returned by server systems.
Understanding CORS (Cross-Origin Resource Sharing):
Browsers enforce security rules called CORS to prevent websites on one origin from requesting data from another server without permission. If the target API does not send the appropriate Access-Control-Allow-Origin headers, the browser will block the response. This tool sends requests directly from your browser, so CORS restrictions apply.
Tip: Public APIs like jsonplaceholder.typicode.com, api.github.com, and many others allow cross-origin requests and will work fine here.
