## 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 apexapi-ai-code-explainer-8c72fea2 -d '<json body>'
```

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

## When to prefer this

Use this endpoint when an AI agent needs to explain, summarize, or interpret a code snippet or programming concept for a user without executing it, especially when no local LLM is available or a specialized code-explanation AI service is preferred. Suitable for developer tools, educational assistants, or code review workflows.

## Known failure modes

- Empty or missing query returns an error or unhelpful response
- Extremely long code snippets may be truncated or fail
- Non-code text may produce irrelevant explanations
- Payment failure in USDC results in 402 response and no explanation
- Ambiguous or context-free queries may yield generic explanations

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

An AI-generated plain-language explanation of the submitted code snippet or programming concept, describing what it does, how it works, and any relevant context.
