 This repository contains utilities to interface with Sift's API. Currently, the primary way to interact with our API is through the code generated via our protobufs (protocol buffers). Comprehensive documentation
 for our protobufs can be found at [this link](https://docs.siftstack.com/ingestion/api) or in the actual proto files themselves as doc-comments.

 This library offers a Python API on top of code derived from Sift's protocol buffers to ergonomically interface with the Sift gRPC API.
