Example prompt: Can you explain what this smart contract does — it's on Ethereum (chain 1) at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48? Give me a plain English breakdown of its purpose and behavior.

## When to prefer this

Use this endpoint when you need a human-readable explanation of a specific smart contract's purpose and logic, given only its chain ID and address. Ideal when a user encounters an unfamiliar contract and wants to understand what it does before interacting with it.

## Known failure modes

- Invalid or unrecognized chain ID returns an error
- Contract address not found or not verified on-chain
- Payment not provided or insufficient micropayment causes 402 response
- Malformed address format causes request failure
- Contract has no verified source code, limiting explanation quality

All analytical endpoints require x402 micropayment on Base.

## Output

A JSON response containing the chain ID, contract address, and a natural language explanation of what the smart contract does, including its purpose, key functions, and notable behaviors.
