Overview

Codex API provides RESTful endpoints to execute source code in diverse programming languages (Python, JavaScript, C++, etc.). It accepts code snippets, language identifiers, and optional input via POST requests, returning execution results (output, errors, status codes) in JSON format. Ideal for integrating real-time code testing into educational platforms, coding interview tools, or developer blogs to enable users to run code without local setup.

Example Integration (JavaScript)

script.js JS

fetch('https://github.com/Jaagrav/CodeX')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
