## How to call it through Zero

```sh
zero fetch --capability axon-smart-contract-explainer-3cbf3378
```

Example prompt: Can you explain in plain English what the smart contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 actually does — is it verified?

## When to prefer this

Use this endpoint when you need a quick, human-readable explanation of what a specific deployed smart contract does — especially useful for due diligence before interacting with an unknown contract, auditing suspicious addresses, or helping non-technical users understand DeFi protocols. Prefer this over general blockchain explorers when you want an AI-synthesized narrative rather than raw bytecode or ABI.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unverified contract with no source code may produce limited or generic explanation
- Payment failure (x402 micropayment not completed) blocks access to the endpoint
- Address does not correspond to a contract (e.g. EOA wallet) may return unexpected results
- Network timeout or Vercel cold-start latency

## 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 queried contract address, a boolean indicating whether the contract is verified on-chain, and a plain-language AI-generated explanation of the contract's purpose and behavior.
