Fonctionnement
How does this tool work?
The tool converts the form values into a valid cURL command. It combines the HTTP method, URL, query parameters, headers, and request body while applying shell-safe quoting to values that may contain spaces or special characters.
Basic or Bearer authentication, redirects, compression, and insecure TLS mode are mapped to explicit cURL flags. No HTTP request is sent at any stage: the browser only generates the final command for you to copy or download.
Use cases
Test an API quickly
Create a reproducible terminal command for checking a REST endpoint.
Document a request
Produce a readable cURL example for technical documentation or onboarding.
Debug an integration
Compare methods, headers, parameters, and request bodies during troubleshooting.

Tips and best practices
- Remove sensitive tokens before sharing generated commands.
- Use HTTPS whenever credentials or private data are involved.
- Prefer environment variables over secrets embedded directly in shell scripts.
Frequently asked questions
Is the request actually sent?
No. The tool only generates the cURL command in your browser and never contacts the entered URL.
Are JSON request bodies supported?
Yes. The builder can add the JSON content type and generate the appropriate data argument.
Can I use Bearer authentication?
Yes. Enter the token in the dedicated field to create the corresponding Authorization header.
