## 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 neurofi-smart-contract-explainer-b64d75a2
```

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, AI-generated explanation of a deployed smart contract by its on-chain address and chain ID, especially for non-technical users who cannot read Solidity or EVM bytecode directly.

## Known failure modes

- Invalid or unrecognized chain ID returns an error
- Contract address does not exist on the specified chain
- Unverified or non-standard contract bytecode cannot be decoded
- Payment not attached or insufficient USDC micropayment returns 402
- Rate limiting or service unavailability on Vercel hosting

## How this service works

NeuroFi 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 natural-language explanation of the smart contract's purpose, functions, and behavior generated by AI.
