gRPC Streaming is one of 26 APIs that [Realtime](https://apis.io/providers/realtime/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include gRPC, Streaming, Bidirectional, HTTP/2, and Protocol. The published artifact set on APIs.io includes API documentation.

gRPC supports four call patterns — unary, server streaming, client streaming, and bidirectional streaming — all carried over HTTP/2. gRPC streams are widely used for internal service-to-service realtime communication, with gRPC-Web bridging to browsers and Connect protocol providing buf.build's HTTP/JSON-friendly alternative.
