This repository is the interface definitions of the APIs of Instill Core, Instill Model, and Instill VDP that support both REST and gRPC protocols. You can also use these definitions with open source tools to generate client libraries, documentation, and other artifacts.
The APIs use Protocol Buffers version 3 (proto3) as the Interface Definition Language (IDL) to define the API interface and the structure of the payload messages. The same interface definition is used for both RESTful (via gRPC-Gateway) and RPC versions of the API, which can be accessed over different wire protocols:
- JSON over HTTP
- Protocol Buffers over gRPC
