Finding gRPC interface

Hi,

I could not find a place that describes gRPC interface and proto contracts.

Where can I find it? Can you help me?

Thanks

Here is the proto definition used by the clients https://github.com/dgraph-io/dgo/blob/master/protos/api.proto. We have clients in Go, JS, Java, Python which you could use to talk to the server using gRPC.
