# gRPC Support on Anypoint Platform

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

Implement and consume gRPC APIs as part of your API-led strategy using gRPC support in Anypoint
Platform. gRPC is a high-performance, open-source framework for remote procedure calls (RPCs) that
uses Protocol Buffers (protobuf) as the interface definition language. gRPC uses HTTP/2 for
transport and is well-suited for server-to-server communication and microservices architectures.

Anypoint Platform supports gRPC in the following products and stages:
