Example prompt: Before I buy, can you run a rug check on this Base token contract — 0x4ed4e862860bed51a9570b96d89af5e1b0efefed — and tell me if it looks safe?

## When to prefer this

Use this endpoint when an AI agent needs a quick, low-cost ($0.02 USDC) risk signal on a Base mainnet token contract before executing a buy, swap, or route. It is purpose-built for Base chain and requires no API key, making it ideal for autonomous DeFi agents that need pre-trade safety checks without complex setup.

## Known failure modes

- Invalid or malformed contract address (not 0x + 40 hex chars) returns an error
- Contract address not found on Base mainnet
- Network timeout or upstream data provider unavailability
- Address is a wallet address rather than a token contract
