About cURL builder

cURL Builder transforms API endpoints, HTTP methods, headers, and request bodies into clean, executable terminal cURL commands. Test and document RESTful API requests with copyable multi-line commands for macOS, Linux, and Windows PowerShell.

When to use cURL builder

• Convert API documentation payloads into copy-paste cURL terminal commands
• Add Authorization Bearer tokens and custom headers to API test requests
• Construct POST, PUT, PATCH, and DELETE requests with formatted JSON payloads
• Troubleshoot API integrations by testing requests directly from the terminal

How it works

Input the HTTP method, endpoint URL, header key-values, and request body. The builder formats the command using standard cURL flags (-X for method, -H for headers, -d for data payload) and provides shell-safe escaping.

Example

Generated cURL Command

Input:

POST https://api.example.com/v1/data
Header: Authorization: Bearer token_xyz
Body: {"status":"active"}

Output:

curl -X POST "https://api.example.com/v1/data" \
  -H "Authorization: Bearer token_xyz" \
  -d '{"status":"active"}'

Privacy & Security Guarantee

cURL builder processes all data locally inside your web browser. No input text, files, credentials, or outputs are ever transmitted to remote servers, logged to analytics databases, or retained across sessions.
