# Sandboxd Code Run

> Hosted one-shot code execution: send a snippet plus optional files, get stdout, stderr, exit code and artifacts back. Daytona execute-code compatible; no daemon to keep warm, priced per run.

An HTTP API at https://sandboxd-code-run.saastemly.com, also an MCP server at https://sandboxd-code-run.saastemly.com/mcp, paid per call: with x402 (USDC on Base; an unpaid call answers 402 Payment Required with the terms, which x402 clients pay automatically), or with prepaid credits or a monthly plan bought by card at https://sandboxd-code-run.saastemly.com (send the API key as Authorization: Bearer <key>).
