## 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 gedx402-jobs-sandboxed-javascript-execution-322feb64
```

Example prompt: Run this JavaScript snippet for me in a sandbox and tell me what it outputs: `const arr = [1,2,3]; console.log(arr.reduce((a,b)=>a+b,0));`

## When to prefer this

Choose this endpoint when you need to execute an arbitrary JavaScript snippet server-side in a secure, sandboxed environment without provisioning your own runtime. It is ideal for evaluating expressions, running data transformations, or testing logic snippets on demand at low cost ($0.01 per call) — especially when you do not need full browser rendering or page scraping (use sibling endpoints for those).

## Known failure modes

- Code with syntax errors may return a non-200 status and an error message in the body
- Long-running or infinite loops may be terminated with a timeout error
- Very large output may be truncated (truncated: true in response)
- Unsupported Node/browser APIs not available in the sandbox will throw runtime errors
- Malformed or missing 'code' parameter returns an error response

## How this service works

Async browser jobs, site crawl, rendered page markdown, screenshot, and PDF, document-to-JSON, document-to-Markdown, one-recipient email, and sandboxed JavaScript.

## Output

Returns a JSON object containing the execution result body (as a string), an HTTP status code (200 on success), a boolean indicating whether the output was truncated, and the content type of the response.
