GetAllGasPriceStream

Introduction

GetAllGasPriceStream provides gas price subscription service on BSC. It pushes the gas price of BSC transactions in recent block to users at all percentile based on gRPC stream. The endpoint is: grpc.bsc-fee.blockrazor.me:443

Rate Limit

	Tier 4	Tier 3	Tier 2	Tier 1	Tier 0
Streams	-	-	-	-	10

Request Parameter

Parameters	Mandatory	Format	Example	Remarks
blockRange	mandatory	int	20	Statistics of gas prices of transactions in the last N blocks, where N ranges from 1 to 20
