Basics

GRPC We recommend using grpc for nextblock api interaction. To get started, the proto specs for grpc can be found here https://github.com/nextblock-ag/nextblock-proto.

Tip floor api The tip floor api returns landed tip percentiles from the last 5 minutes. You can use it to dynamically adjust your tips. The result is kept in line with jito tip floor api on purpose to make interop easier.
