## What it is
The canonical repository of Protocol Buffers (proto3) interface definitions for public Google APIs, supporting both REST and gRPC access. These definitions can be consumed directly or used with code generators to produce client libraries, documentation, and other artifacts in many languages.

## Use cases
- generate gRPC client libraries for Google Cloud APIs
- understand the exact request and response schemas of a Google API
- build custom API clients from proto definitions
- generate API documentation from interface definitions
- consume Google APIs over gRPC instead of REST
- keep proto dependencies in sync with Google's latest API versions

## When to choose
- you need authoritative, up-to-date proto definitions for Google APIs
- you are generating client libraries in a language without an official SDK
- you want to call Google APIs over gRPC for performance
- you need to inspect exact API contracts, fields, and versions

## When to avoid
- you just want a ready-made client library for your language (use Google Cloud Client Libraries instead)
- you need API definitions for non-Google services
- you are not working with gRPC, protobuf, or Google APIs at all

## Facets
- artifact type: dataset
- maturity: active
- function: rpc, serialization, api-framework, sdk, developer-tools
- domain: apis, developer-tools, cloud-computing, backend
- platform: cross-platform, jvm, go, python, cpp
- tags: protocol-buffers, grpc, google-cloud, api-definitions, proto3, bazel, rest, client-library-generation, nodejs
