cURL Command Constructor

A purely visual syntax compiler for HTTP APIs. Build complex parameterized payloads and HTTP headers through an intuitive UI, and the engine will transpile it directly into executable cURL (Bash), Node.js (fetch), and Python (requests) scripting languages.

Target Endpoint

HTTP Headers

Body Payload

cURL (Bash)

curl --request GET \
  --url 'https://api.github.com/users/octocat' \
  --header 'Authorization: Bearer YOUR_TOKEN_HERE' \
  --header 'Content-Type: application/json'

JS (Fetch)

const options = {
  method: 'GET',
  headers: "Authorization": "Bearer YOUR_TOKEN_HERE",
    "Content-Type": "application/json",
};

fetch('https://api.github.com/users/octocat', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));

Python (Requests)

import requests

url = "https://api.github.com/users/octocat"

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

response = requests.request("GET", url, data=payload, headers=headers)

print(response.text)

What is the HTTP Request Builder?

Lets you build an HTTP request visually — method, URL, headers, and a JSON body — and get the same request back as a ready-to-run cURL command, a JavaScript fetch() call, or a Python requests script.

How it works

Every field you fill in feeds three small string-building functions, one per output format, that assemble the same method/URL/headers/body into bash flags, a JS fetch() options object, or a Python requests.request() call, escaping quotes and formatting the body along the way. Nothing is actually sent — it only generates the text.

SysAdmin & security use cases

Turn a request you're testing in the UI into a cURL command to paste into a terminal or CI script.
Grab the fetch() version to drop straight into a React or Next.js component.
Generate the Python requests equivalent for a quick test script without writing boilerplate by hand.
Work out the right header and body combination for an API before committing it to real code.
