answers 402
Should I submit this Base transaction now, and at what fee? One call returns submit-or-wait, max fee per gas and priority fee in gwei (EIP-1559), and the estimated cost in USD for an ETH transfer, USDC ERC-20 transfer, or x402 settlement on Base mainnet. Live gas price and congestion from Base RPC blocks, no API key. For bots that queue transactions: call before every send.
