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 plain-language AI-generated explanation of what the contract does, its purpose, and key functionality.
Example use cases
Example prompt
“Can you explain what the smart contract at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 does in plain English — is it verified and what's its main purpose?”
Technical details
Endpoint
GEThttps://neurofi-chi.vercel.app/api/explain/%7Baddress%7DWhen to prefer
Use this endpoint when you need a quick, human-readable explanation of any smart contract by address — especially useful when a user wants to understand a contract's purpose without reading raw Solidity. Prefer this over general code analysis tools when the subject is an on-chain contract address specifically, and you want verification status alongside the explanation.
Side effects
- Invalid or malformed contract address returns an error
- Unverified or undeployed contract may return limited explanation
- Network or payment failure (x402 micropayment not processed) returns 402
- Contract on unsupported chain returns error or empty result
- Rate limiting or service downtime returns 5xx error
