Analyze REST API Client Online
Send GET, POST, PUT, PATCH and DELETE requests and inspect the live response. Use REST API Client in your browser with no signup, no daily limit, and no backend processing for tool input.
Problem
You need to understand a dataset or payload before deciding what to clean, transform, or export.
What to do
Analysis gives a fast first pass on quality and structure. Use the findings to decide whether the data is ready or needs more cleanup.
- 1Load the dataset or payload into REST API Client.
- 2Review counts, types, warnings, and summaries.
- 3Use the findings to clean, validate, visualize, or export the data.
Use the browser tool
REST API Client is a free, browser-based HTTP client for calling APIs: send GET, POST, PUT, PATCH, DELETE, HEAD or OPTIONS requests, set headers, auth and a body, then read the status, timing and response. Requests go directly from your browser to the API you name — DataXForge has no server in the path and never sees your requests, your responses or your tokens. Saved collections and environment variables stay in this browser's local storage.
People also ask
- Where do my requests actually go?
- Straight from your browser to the URL you enter. DataXForge is a static site with no backend, so there is no server of ours in the path — your requests, responses, headers and tokens are never sent to us and never stored by us.
- Why does my request fail with a CORS error when curl works fine?
- Because a browser will not let a page read a response from another origin unless that API opts in with an Access-Control-Allow-Origin header. This is a browser security rule, not a limitation we can code around — it is exactly why Postman ships a desktop app. When it happens the tool explains which header is missing and gives you a ready-to-run curl command for your terminal, which has no such restriction.
- Why are some headers missing from the response?
- Browsers only expose six CORS-safelisted response headers unless the server adds Access-Control-Expose-Headers. The others were sent but the browser hides them from the page. The tool tells you when that is what you are looking at.
