● verified · data.crypto · 0.01 USDC/call · base

Live gas price on BNB Chain, Polygon, Arbitrum, Base, Avalanche and Optimism, converted to USD and ranked cheapest-first. Gwei is NOT comparable across chains because the gas token differs in price; USD is the only honest ranking. Returns chains[] with gasPriceGwei, baseFeeGwei, nativeUsd and costUsd for transfer, erc20Transfer and swap, plus cheapest and mostExpensive. Optional ?chain=all or one chain key; 400 unknown_chain otherwise. Send chain=all - a bare call skips the free tier.
