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.
Example use cases
Remote Python script validation
“I've got a Python script that processes some data — can you run it for me and show me what it prints and whether it exits cleanly?”
Multi-file JavaScript execution
“Run these three JavaScript files together as a program and give me the stdout and exit code — the entry point is index.js.”
Automated code output testing
“Execute this snippet in a sandbox and tell me if it errors out or produces the expected output: I don't want to run it on my machine.”
Technical details
Endpoint
POSThttps://whatchuneed.vercel.app/api/code/multiWhen to prefer
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.
Side effects
- 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
