# Code Sandbox

> Use this tool when you need to execute and test code snippets in a secure and isolated environment, solving problems such as debugging, testing, and validating code without compromising your main system. It takes in Python, JavaScript, and SQL code as input and returns the output, with a per-execution billing system using x402 micropayments. Ideal for use cases where code testing and validation are required, such as development, debugging, and education.
