# Citiview Code Runner

> Citiview Code Runner is a paid API for AI agents from agents.citiviewgroup.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-15).

Executes Python 3.13, JavaScript (Node 24), or bash scripts in an isolated container and returns stdout, stderr, and exit code

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 citiview-code-runner-88645ab2
```

Example prompt: Can you run this Python script for me and tell me what it outputs? `import numpy as np; print(np.mean([1, 2, 3, 4, 5]))` — use a 10-second timeout.

## When to prefer this

Choose this endpoint when you need a truly sandboxed, ephemeral execution environment for Python 3.13 (with numpy/pandas), JavaScript (Node 24), or bash — especially for quick calculations, data wrangling, or snippet testing without setting up local infrastructure. Prefer it over general-purpose LLM code interpretation when you need real, deterministic code execution with actual stdout/stderr/exit code output, or when you need numpy/pandas available by default.

## Known failure modes

- Code that exceeds the requested timeout_s will be terminated and return a non-zero exit code
- Syntax errors in the submitted code will produce error output in stderr
- Code attempting network access will fail silently or error since the container has no internet
- Unsupported language values other than python, javascript, or bash will be rejected
- Timeout values outside the 1–60 range may be rejected or clamped

## How this service works

Run Python 3.13 (numpy, pandas), JavaScript (Node 24) or bash in a fresh isolated container with no Internet access, and get stdout, stderr and the exit code. For calculations, data wrangling, parsing and testing snippets. $0.005 for a 10 s limit, $0.01 up to 30 s, $0.02 up to 60 s. Also callable as GET with the same fields as query parameters.

## Output

Returns the captured stdout and stderr strings from the executed program, along with the integer exit code. Execution happens in a fresh isolated container with no internet access, so results reflect pure computation only.
