Universal cURL/API Tester

Builds a cURL command and runs the request via fetch or a separate PHP proxy.

Request
One header per line: Name: value
If body is empty, GET is used; otherwise POST.
Generated cURL
Response log
No requests yet.
Request storage on the server

Except when you explicitly use «Share snapshot», this service does not store request or response bodies on the server for archiving or later review. Normal sends and the log in this tab exist only in your browser; form fields may be saved locally until you clear them.
