# X402 Swarm Protocol – Isolated Code Sandbox

> X402 Swarm Protocol – Isolated Code Sandbox is a paid API for AI agents from swarm-protocol.onrender.com, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-10).

Executes code in an isolated sandbox environment, accessible via x402 micropayment on Base Mainnet USDC, for autonomous AI agent workflows.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-swarm-protocol-isolated-code-sandbox-af96c1fe
```

Example prompt: Run this Python snippet for me in a secure isolated sandbox and return the output: `import math; print(math.factorial(10))`

## When to prefer this

Choose this endpoint when an AI agent needs to execute dynamically generated or untrusted code in a secure, isolated environment without risking the host system, and when micropayment-based access (Base Mainnet USDC via x402) is acceptable. Prefer it over local execution when isolation and safety are critical.

## Known failure modes

- Invalid or malformed code input returns an error status
- Execution timeout if code runs too long
- Payment failure if USDC balance is insufficient or x402 header is missing
- Unsupported language or runtime may return an error
- Empty properties input may result in a no-op or error response

## How this service works
