About this tool
IconVault's cURL Builder creates correct, shell-safe cURL commands from simple form fields. Pick the HTTP method (GET, POST, PUT, PATCH, DELETE and more), add headers, query parameters and a request body (JSON, form-encoded or plain text), set Basic or Bearer auth, and the tool assembles a properly quoted command with safe escaping of single quotes. You can also paste an existing cURL command back in to edit and rebuild it.
Everything runs 100% in your browser: no request is ever sent and nothing is uploaded, so API keys and tokens stay on your machine. Copy the finished command, download it as a shell snippet, and use it for testing REST APIs, debugging webhooks or documenting endpoints. It is free to use with no account.
