gas
Reads eth_feeHistory over the last ten blocks with reward percentiles 25, 50 and 75, and falls back to eth_gasPrice when a node does not serve fee history. base_fee_gwei is the base fee of the next block, not of the last one, because that is the fee a transaction sent now will actually pay. recommended_gwei is a bid, not an observation: priority at the median plus a base fee doubled to survive several full blocks, and the rule is stated in recommended_rule. cost_usd converts that into.
