FAQ

Is this REST client free?

Yes. Send GET, POST, PUT, PATCH, and DELETE requests from your browser without an account.

Why can’t I reach localhost?

Browsers enforce CORS. Use a tunnel (for example ngrok) or test against a public URL with proper CORS headers.

Are my API keys stored?

Headers and bodies stay in your session; they are not persisted on JsonOnlineParse servers for this client.

How do I view JSON responses?

The response panel formats JSON when possible so you can copy or inspect status, headers, and body together.
