Frequently Asked Questions
?What is a REST API Reader?
It is a utility that acts as an HTTP client. It sends requests to web servers and displays the responses, helping developers understand how an API behaves.
?Why is my request blocked by CORS?
CORS (Cross-Origin Resource Sharing) is a security feature in browsers. If a server doesn't explicitly allow txtoolbox.com, the browser blocks the request. You can use our 'CORS Proxy' toggle to route the request through a server to bypass this.
?Is my data stored or tracked?
No. All requests happen in your own browser. We do not store URLs, headers, or response data on our servers.
