01 / Your cURL request
Use POSIX quotes and \ line continuations. Remove real credentials before sharing generated code.
02 / Generated code
.NET 6+ · Console application
Private by design
Your command stays in this page. This tool does not execute cURL, contact the target URL or save your input.
Know the limits
File uploads, multipart forms, shell variables and unsupported flags produce an explicit error. Browser Fetch still follows CORS rules. Review the output before using it.
How do I use the generated code?
Choose a language and copy the result. C# output targets a .NET 6+ console app. Fetch output uses top-level await in a JavaScript module, or can be placed inside an async function.
Does this send my API request?
No. Conversion only produces text. Requests run when you execute the generated code in your own environment.
