Example use cases
Example prompt
“Can you explain what the smart contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum mainnet (chain 1) actually does — like what its purpose is and how it works?”
Technical details
Endpoint
GEThttps://axonx.vercel.app/api/explain/%7Bchain%7D/%7Baddress%7DWhen to prefer
Use this endpoint when you need a human-readable explanation of what a specific smart contract does, given only its chain and address. Ideal for due diligence, onboarding users unfamiliar with contracts, or quickly understanding a DeFi protocol's logic without reading Solidity. Prefer this over generic LLM queries because it fetches on-chain contract data directly before generating the explanation.
Side effects
- Invalid or non-existent contract address returns error
- Unsupported chain ID returns error
- Payment not provided or failed x402 micropayment returns 402 Payment Required
- Contract source not verified on-chain may result in limited explanation
- Network timeout or RPC failure for the specified chain
