## How to call it through Zero

```sh
zero fetch --capability axon-smart-contract-explainer-49e0ee8e
```

Example prompt: Can you explain what the smart contract at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D does — is it verified, and what's its purpose in plain English?

## When to prefer this

Choose this endpoint when you need a human-readable explanation of what a specific EVM smart contract does, especially when evaluating unknown contracts before interacting with them or investing. It is particularly useful when verification status matters and when you want AI-generated natural language summaries rather than raw ABI or bytecode.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unverified or non-existent contract may return limited or no explanation
- Micropayment failure (insufficient USDC or x402 header missing) results in 402 Payment Required
- Network or RPC timeout may cause delayed or failed response
- Contract on unsupported chain may not return results

## 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

Returns a JSON object containing the queried contract address, a boolean indicating whether the contract is verified on-chain, and a plain-language explanation of what the contract does, its purpose, and key functions.
