cURL to Code

cURL (Client URL) is a command-line tool and library for transferring data using URLs. It supports dozens of protocols — HTTP, HTTPS, FTP, SMTP and more. For developers, cURL is the universal way to make HTTP requests from the terminal, test APIs, and inspect server responses without writing any code.

API documentation almost always includes cURL examples because cURL works on every OS and is the lowest common denominator. But writing production code with cURL commands is impractical — you need idiomatic HTTP clients in your language. This tool converts any cURL command to ready-to-run code in Go, Python, JavaScript, PHP, or Ruby.

Input cURL:

curl -X POST https://api.example.com/users \
  -H "Authorization: Bearer token123" \
  -H "Content-Type: application/json" \
  -d '{"name":"Ravi","role":"admin"}'

Generated Go (net/http):

package main

import (
	"context"
	"fmt"
	"net/http"
	"strings"
)

func main() {
	ctx := context.Background()
	body := strings.NewReader(`{"name":"Ravi","role":"admin"}`)
	req, err := http.NewRequestWithContext(ctx, http.MethodPost, "https://api.example.com/users", body)
	if err != nil { panic(err) }
	req.Header.Set("Authorization", "Bearer token123")
	req.Header.Set("Content-Type", "application/json")
	resp, err := http.DefaultClient.Do(req)
	if err != nil { panic(err) }
	defer resp.Body.Close()
	fmt.Println(resp.Status)
}
