}An engineer copies an API snippet from third-party developer docs with bearer authentication and JSON payload, converting it into production backend and frontend code.
| Original cURL | curl -X POST https://api.example.com/v1/checkout -H "Authorization: Bearer secret_live_token" -H "Content-Type: application/json" -d '{"sku": "PRO-99", "quantity": 2}' |
| Generated Python Requests | import requests url = "https://api.example.com/v1/checkout" headers = { "Authorization": "Bearer secret_live_token", "Content-Type": "application/json", } payload = { "sku": "PRO-99", "quantity": 2, } response = requests.post(url, headers=headers, json=payload) print(response.json()) |
💡 Both frontend and backend code snippets are ready to run in seconds with correct header formatting and payload serialization.
Paste any single-line or multi-line cURL command into the input editor, or choose from popular preset API requests.
Select your target programming language or library (JavaScript Fetch, Axios, Python Requests, Go net/http, PHP cURL, or Node.js).
Inspect parsed HTTP parameters (method, headers, query parameters, request body) and click Copy Code to use immediately in your project.
Generate idiomatic code for JavaScript Fetch, Axios, Python Requests, Go net/http, PHP cURL, and Node.js from a single command line.
Parsing and code generation occur entirely in memory inside your browser. No API tokens, passwords, or headers are transmitted across any network.
Inspect headers, query parameters, authorization schemes, and parsed JSON payloads in a dedicated breakdown table.
Yes. It automatically handles line continuation backslashes (\), carriage returns, enclosed quotes, and shell escape flags from terminal copy-pastes.
No. The cURL parser and code generators run 100% in your local browser sandbox. No network requests are made, and your authorization headers and payload data never leave your device.
All HTTP methods (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS) are supported along with Bearer tokens, Basic Authentication (-u username:password), custom headers (-H), query strings, JSON payloads, and URL-encoded form data.
