## 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 axon-smart-contract-explainer-51290b84
```

Example prompt: Can you explain what the smart contract at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on chain 1 (Ethereum mainnet) actually does in plain English?

## When to prefer this

Use this endpoint when you need a human-readable explanation of a deployed smart contract and have its chain ID and address. Ideal for due diligence, user education, or quickly understanding an unknown contract without reading raw Solidity. Prefer over general LLMs when you want a crypto-specialized AI that can fetch and interpret on-chain contract data directly.

## Known failure modes

- Invalid or unrecognized contract address returns an error
- Unsupported chain ID returns an error or empty explanation
- Payment not fulfilled (x402 micropayment missing or rejected) returns 402 Payment Required
- Contract source not verified on-chain may result in limited or incomplete explanation
- Rate limiting if too many requests are made in quick succession

## 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 chain ID, contract address, and an AI-generated plain-language explanation describing what the smart contract does, its purpose, key functions, and behavior
