**APIs profiled:** 1

Twirp is a simple RPC framework built on Protocol Buffers, created by Twitch, that generates routing and serialization code from Protobuf service definitions for Go and other languages. Similar to gRPC but runs on the standard library's net/http Server without custom HTTP server or transport implementations. Supports both binary Protobuf and JSON serialization, making debugging easy. Uses HTTP POST for all requests with URLs in the format /twirp/[Package].[Service]/[Method]. Protocol version 7 is the current stable version. Licensed under Apache 2.0.
