cURL Command Builder

Visually build curl commands — choose method, headers, auth, body, and get the ready-to-run curl command

cURL Command Builder — Visually Construct HTTP Requests with Method Selection, Headers, Authentication, Request Body, and One-Click Copy to Terminal

  1. Select your HTTP method from the dropdown (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS) and enter the full API endpoint URL. The method choice determines what other options are available — POST, PUT, and PATCH enable the request body section, while GET and HEAD focus on headers and query parameters. cURL (Client URL) is the most widely used command-line HTTP client, available by default on macOS, Linux, and Windows 10+, and is the universal language for sharing API requests in documentation, bug reports, and support tickets.
  2. Configure request details through the structured form sections. Authentication: choose between None, Basic Auth (provides a Base64-encoded username:password header), or Bearer Token (adds an Authorization: Bearer <token> header — the standard for OAuth 2.0 and JWT-based APIs). Headers: add custom HTTP headers as key-value pairs (Content-Type, Accept, User-Agent, X-API-Key, etc.) — the builder automatically includes common header presets. Request Body: for methods that support it, enter JSON, form-encoded, or raw text body content. Options: toggle flags like --location (follow redirects), --insecure (skip SSL verification — use with caution), and --verbose (detailed output for debugging).
  3. Review the generated cURL command displayed at the bottom — it updates in real-time as you modify any setting. Click Copy to copy the complete command to your clipboard, then paste it directly into your terminal to execute. The builder formats the command with proper escaping, line continuation characters (\), and correct flag ordering. Use this builder to: prototype API calls before writing code, generate reproducible test commands for bug reports, create documentation examples for REST APIs, and share exact HTTP request configurations with teammates. All command construction happens entirely in your browser — your API URLs and credentials never leave your device.
