## 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 nexusapi-ai-code-explainer-68e86b83 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when an AI agent needs to explain or summarize a code snippet to a user in plain English, particularly in a pay-per-call context without needing to manage API keys. Best for on-demand code comprehension tasks where a human-readable explanation of code logic is needed.

## Known failure modes

- Empty or missing query field returns an error
- Extremely long code snippets may be truncated or rejected
- Ambiguous non-code queries may return generic or unhelpful explanations
- Payment failure in USDC returns 402 Payment Required
- Server unavailability returns 500 error
