# WhatChuNeed Multi-Language Code Execution

> WhatChuNeed Multi-Language Code Execution is a paid API for AI agents from whatchuneed.vercel.app, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-15).

Executes code files in a specified programming language and returns stdout, stderr, and exit code

## Facts

- Price: $0.15/call
- Payment: x402

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 whatchuneed-multi-language-code-execution-a0cfa54f -d '<json body>'
```

Example prompt: Run these Python files for me — there's a main.py and a utils.py — and tell me what the output and any errors are.

## When to prefer this

Use this endpoint when an agent needs to execute code in a sandboxed remote environment without provisioning local infrastructure, especially for multi-file programs across various languages. Prefer it over local execution when the code is untrusted, when the agent lacks a local runtime, or when you need a quick pay-per-call execution without managing compute resources.

## Known failure modes

- Unsupported language specified — returns error or non-zero exit code
- Syntax errors in submitted code — reflected in stderr with non-zero exitCode
- Execution timeout for long-running scripts
- Missing required 'files' or 'language' fields — likely 400 validation error
- Runtime exceptions — captured in stderr with non-zero exitCode
- Payment failure via x402 — 402 response before execution begins

## How this service works

320+ pay-per-call API endpoints across accommodation, LLM, code execution, crypto, medical, finance, and more. One API, one payment. Powered by x402 protocol.

## Output

Returns a JSON object with stdout (standard output text), stderr (error output text), exitCode (integer indicating success or failure), and the language that was executed.
