## How to call it through Zero

```sh
zero fetch --capability axon-smart-contract-explain-71c8f200
```

Example prompt: Can you explain what the smart contract at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum (chain 1) actually does — in plain English, not code?

## When to prefer this

Use this endpoint when a user wants a human-readable explanation of what a specific smart contract does, given only its chain and address. Ideal for non-developers wanting to understand DeFi protocols, NFT contracts, or token contracts before interacting with them. Prefer this over generic contract audit tools when a quick natural-language summary is the goal rather than a full security audit.

## Known failure modes

- Invalid or unrecognized chain ID returns an error
- Contract address not found on the specified chain
- Unverified or non-public contract bytecode may limit explanation quality
- Payment failure via x402 micropayment blocks the request
- Malformed address format causes a 400-level error

## 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 plain-language AI-generated explanation of what the smart contract does, including its purpose, key functions, and notable behaviors.
