# 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: <mark style="color:$primary;">grpc.bsc-fee.blockrazor.me:443</mark>

### Price

The price is $300 per data stream per month. Please go to the [Pricing](https://blockrazor.io/#/pricing) page to purchase.
