## 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-b224443e
```

Example prompt: Can you explain in plain English what the smart contract at 0x1234567890abcdef1234567890abcdef12345678 actually does — is it verified and what's its purpose?

## When to prefer this

Use this endpoint when you need a quick, human-readable explanation of what a deployed smart contract does without manually reading Solidity source code. Ideal for due diligence, risk assessment, or helping non-technical users understand contract behavior. Prefer over manual block explorers when you want AI-synthesized interpretation rather than raw bytecode or ABI.

## Known failure modes

- Invalid or malformed contract address returns an error
- Unverified contract with no available source code may produce limited explanation
- Address not found on supported chain returns 404 or empty result
- Micropayment not completed or rejected causes 402 Payment Required response
- Network or RPC timeout results in 500 error

## 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 queried contract address, a boolean indicating whether the contract is verified on-chain, and a human-readable AI-generated explanation of what the contract does, its logic, and its purpose.
