# gRPC API overview

YDB provides the gRPC API, which you can use to manage your DB [resources](https://ydb.tech/docs/en/concepts/datamodel/index.md) and data. API methods and data structures are described using [Protocol Buffers](https://developers.google.com/protocol-buffers/docs/proto3) (proto 3). For more information, see [.proto specifications with comments](https://github.com/ydb-platform/ydb-api-protos).
