## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ephemeral-docker-jail-mcp-489af0ad -d '<json body>'
```

Example prompt: Run this Python snippet in a secure sandboxed Docker jail and give me back the output: `import math; print(math.factorial(10))`

## When to prefer this

Choose this endpoint when you need to execute arbitrary or untrusted code in a fully isolated, ephemeral environment with no risk of side effects on the host system. Ideal for running user-submitted code, testing scripts, or evaluating commands safely. Prefer over local execution when security isolation is required.

## Known failure modes

- Malformed or empty data payload returns an error
- Execution timeout if the code runs too long
- Container spin-up failure under high load
- Unsupported runtime or command syntax causes non-zero exit
- Network or infrastructure errors return a 5xx response

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns the output produced by executing the submitted code or command inside an ephemeral Docker container jail, including stdout, stderr, and exit status. The container is discarded after execution, leaving no persistent state.
