cURL to Python Converter

Free online cURL command converter. Convert cURL requests into clean Python requests, Python httpx, JavaScript fetch, Node.js Axios, and Go code snippets instantly.

Sample cURL:

cURL Command Input

Generated Code

import requests

url = "https://api.example.com/v1/users"

headers = {
    "Authorization": "Bearer my_secret_token_123",
    "Content-Type": "application/json",
}

payload = {
    "name": "Alice Johnson",
    "email": "alice@example.com",
    "role": "admin"
}

response = requests.post(url, headers=headers, json=payload)

print("Status Code:", response.status_code)
print("Response Body:", response.json() if "application/json" in response.headers.get("content-type", "") else response.text)

Quick Answer: How to Convert cURL to Python Requests

To convert a cURL command into Python, map the cURL components into requests parameters: extract the URL (url = "..."), HTTP method (requests.post or requests.get), headers (as a Python dictionary headers={"Authorization": "Bearer..."}), and JSON data (as a dictionary in json=payload).

Supported Language Client Architectures

Python (requests & httpx)

Sync and Async support. Automatic JSON serialization, connection pooling, and session cookies.

JavaScript (fetch & axios)

Native browser Web Fetch API with async/await, and enterprise Node.js Axios interceptors.

Go (net/http)

Idiomatic standard library Go client with request buffers, custom headers, and body streaming.

Supported cURL Flags & Syntax Reference

-X, --requestHTTP Method (GET, POST, PUT, DELETE, PATCH)requests.get(), requests.post()
-H, --headerRequest Headers (Auth, Content-Type, API keys)headers={"Key": "Value"}
-d, --data-rawJSON or URL-encoded body payloadjson=payload / data=payload
-u, --userHTTP Basic Authentication (username:password)auth=("user", "pass")
-k, --insecureSkip SSL certificate verificationverify=False
-L, --locationFollow HTTP 301/302 redirectsallow_redirects=True (default)

Step-by-Step Case Study: Converting an Authenticated POST API Request

Suppose you copy the following cURL command from your developer documentation:

curl -X POST 'https://api.stripe.com/v1/customers' \
  -H 'Authorization: Bearer sk_test_51Mz...' \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -d 'name=Jenny Rosen&email=jenny@example.com'

The converter extracts the parameters into clean, idiomatic Python code:

import requests

url = "https://api.stripe.com/v1/customers"
headers = {
    "Authorization": "Bearer sk_test_51Mz...",
    "Content-Type": "application/x-www-form-urlencoded"
}
payload = {
    "name": "Jenny Rosen",
    "email": "jenny@example.com"
}

response = requests.post(url, headers=headers, data=payload)
print(response.status_code)
print(response.json())

Best Practices for Production API Integration

  • Environment Variables: Store API tokens in .env files or AWS Secrets Manager rather than committing plain text credentials to Git.
  • Timeout Protection: Always set explicit timeouts in requests (e.g. requests.get(url, timeout=10)) to prevent hung threads.
  • Retry Logic: Use urllib3.util.Retry with HTTPAdapter to automatically handle transient 429 Rate Limit and 503 Service Unavailable errors.

Frequently Asked Questions

How do I copy a cURL command from Chrome DevTools or Safari?
Open Developer Tools (F12 or Cmd+Option+I on Mac), go to the Network tab, trigger the action on the webpage, right-click the desired HTTP request in the list, hover over 'Copy', and click 'Copy as cURL (bash)'. You can paste that command directly into this converter to generate working code instantly.
What is the difference between Python requests and Python httpx?
Python 'requests' is the industry standard synchronous HTTP client library. 'httpx' is a modern next-generation library that supports both standard synchronous requests AND full asynchronous (async/await) execution (with asyncio and trio), HTTP/2 support, and strict type annotations.
Is my cURL command, API key, or authentication token sent to any external server?
No. All parsing, header extraction, and code generation executes 100% locally in your browser using client-side JavaScript. Your confidential Bearer tokens, API credentials, and data payloads are never logged or transmitted across the internet.
How do I install the required Python libraries?
Run 'pip install requests' or 'pip install httpx' in your terminal, virtual environment (venv), or command prompt before executing the generated Python script.
How does the converter handle JSON vs Form Data bodies?
The parser automatically detects whether the -d / --data payload is valid JSON. If valid JSON is detected, it formats it as a native Python dictionary or JavaScript object and passes it to requests.post(url, json=data) or JSON.stringify(data). If it is url-encoded form data (e.g. key=val&foo=bar), it maps it to data=payload.
Can I convert cURL commands into JavaScript Fetch or Axios?
Yes. In addition to Python requests and httpx, this tool converts cURL commands into modern browser JavaScript fetch (with async/await), Node.js Axios, and Go net/http code snippets with complete headers and payloads.
How do I securely store API keys in Python?
Instead of hardcoding private tokens in your source code, use Python's built-in 'os' module with a '.env' file: install 'python-dotenv', create a .env file with API_KEY=your_token, and access it in Python via 'os.getenv("API_KEY")'.
