## 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-9617d24f -d '<json body>'
```

Example prompt: Can you explain what this Python function does? Here's the code: `def fib(n): return n if n <= 1 else fib(n-1) + fib(n-2)`

## When to prefer this

Choose this endpoint when you need quick, AI-generated natural language explanations of code snippets or programming concepts without setting up API keys. It is well-suited for agents that help developers understand unfamiliar code, onboard new team members, or assist non-technical stakeholders in comprehending technical logic. Pay-per-call USDC pricing makes it suitable for low-volume or sporadic use cases.

## Known failure modes

- Empty or missing query field returns an error or generic response
- Very long code snippets may be truncated or return incomplete explanations
- Ambiguous or context-free snippets may produce vague explanations
- Payment failure in USDC on Base will result in a 402 response before the endpoint is reached
- Rate limiting or service unavailability may return 5xx errors
