## How to call it through Zero

```sh
zero fetch --capability axon-smart-contract-explainer-b6c17fb2
```

Example prompt: Can you explain what this smart contract does? The address is 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — give me a plain-English breakdown of its purpose and logic.

## When to prefer this

Use this endpoint when a user wants a plain-English explanation of a deployed smart contract by its address, particularly for DeFi due diligence, contract auditing, or understanding an unfamiliar protocol. Prefer this over generic LLM prompting when you need a structured, verified response tied to the actual on-chain contract source.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unverified contracts may yield incomplete or unavailable source code for explanation
- Payment failure via x402 micropayment protocol blocks the response
- Contract address not found on supported chain returns an error
- Rate limiting or service downtime on Vercel deployment

## How this service works

Axon provides AI-powered crypto intelligence endpoints covering token research, market analysis, contract auditing, sentiment tracking, news summarization, portfolio advice, deep research, text translation, language detection, SEO content generation, and contract explanation. All analytical endpoints require x402 micropayment on Base.

## Output

A JSON object containing the contract address, a boolean indicating whether the contract is verified, and a natural-language explanation of what the smart contract does, generated by AI.
