## 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-22812c1c
```

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

## When to prefer this

Use this endpoint when you need a quick, AI-generated plain-language explanation of a specific smart contract given its chain and address. It is ideal for non-technical users, security researchers, or developers doing rapid due diligence who want to understand a contract's purpose without manually reading Solidity code. Prefer this over generic code analysis tools when working specifically with on-chain EVM contracts and needing crypto-domain context.

## Known failure modes

- Invalid or unrecognized contract address returns an error
- Unsupported chain ID results in a lookup failure
- Unverified or undeployed contracts may return no explanation
- Payment not received or x402 micropayment failure blocks the response
- Network timeout or Vercel cold start delay causes request failure

## 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 a human-readable AI-generated explanation of what the smart contract does, including its purpose, key functions, and any notable behaviors or risks.
