Overview
Real-time gas price oracle for Base, Ethereum, Optimism, Arbitrum, and Polygon. Reads the chain's latest block, derives the EIP-1559 base fee, suggests safe-low / standard / fast priority-fee tiers with a total recommended maxFeePerGas, and converts the cost to USD for common transactions (transfer, ERC-20 transfer, Uniswap swap, NFT mint). Use it as a gas price API, EIP-1559 fee estimator, etherscan-gas alternative, or pre-transaction cost calculator.
