**Documentation:** https://grpc.io/docs/what-is-grpc/introduction/

gRPC Core Framework is one of 7 APIs that [gRPC](https://apis.io/providers/grpc/) publishes on the [APIs.io](https://apis.io/) network. This API exposes 2 JSON Schema definitions. Tagged areas include HTTP/2, Protocol Buffers, RPC, and Streaming. The published artifact set on APIs.io includes API documentation, an API reference, authentication docs, a GitHub repository, a JSON-LD context, and 2 JSON Schemas.

The gRPC core framework defines the RPC protocol, service definition format using Protocol Buffers, and the fundamental call lifecycle including unary, server-streaming, client-streaming, and bidirectional streaming patterns over HTTP/2. It is the foundational specification implemented by all language-specific gRPC SDKs.
