Example use cases
Pre-transaction gas cost check
“Before I submit this Base transaction, can you check what the current gas price is on Base mainnet so I know how much it'll cost me?”
Gas price monitoring for DeFi bot
“What's the live gas price on Base right now? I only want my bot to execute swaps when gas is below a certain threshold.”
Cost estimation for smart contract deployment
“I'm about to deploy a contract on Base — can you pull the current gas price so I can estimate my total deployment cost?”
