## 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-3b8bc569
```

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 fast, AI-generated plain-language explanation of what a specific smart contract does, given its on-chain address and chain. Ideal when a user wants to understand an unfamiliar contract before interacting with it, without manually reading Solidity source code. Prefer over general blockchain explorers when a human-readable narrative summary is needed rather than raw ABI or bytecode.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty explanation
- Unsupported chain ID results in a 400 or 422 error
- Payment not provided or insufficient USDC micropayment triggers a 402 Payment Required response
- Contract has no verified source code or bytecode available, leading to a vague or failed explanation
- Rate limiting or upstream AI service unavailability causes a 503 or timeout

## 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 what the smart contract does, including its purpose, key functions, and behavior.
