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 basebuilder2-code-explain-36fff8bc -d '<json body>'
```

Example prompt: Can you explain what this JavaScript function does in plain English? Here's the code: `function debounce(fn, delay) { let timer; return function(...args) { clearTimeout(timer); timer = setTimeout(() => fn.apply(this, args), delay); }; }`

## When to prefer this

Choose this endpoint when you need a quick, paid AI-powered explanation of a code snippet without setting up your own LLM integration. Ideal for developer tools, code review assistants, or educational platforms that need per-call billing via USDC crypto payments through the x402 protocol.

## Known failure modes

- Empty or missing code input returns an error or unhelpful response
- Unsupported or obfuscated code may produce inaccurate explanations
- Payment failure via x402 protocol results in 402 response blocking access
- Very large code inputs may be truncated or refused
- Network timeout if inference takes too long
