What it is and what it does
This is Google's official Python client for the Discovery Engine API, a managed service for building search and recommendation systems powered by generative AI. It wraps the underlying gRPC and REST APIs, providing Python-friendly classes and methods to interact with Discovery Engine resources—datastores, search configurations, recommendations, and generative AI features.
The library is part of the broader google-cloud-python ecosystem and follows Google Cloud's standard patterns for authentication, configuration, and error handling. It requires Python 3.10 or later and depends on google-api-core for common functionality, google-auth for credential management, and gRPC libraries for transport. You'll need a Google Cloud project with Discovery Engine enabled and appropriate credentials configured before making API calls.
Use it for
- Build a search interface that indexes and queries custom documents or web content using Discovery Engine's managed search.
- Integrate personalized product recommendations into an e-commerce or content platform via the Recommendations API.
- Create a generative AI-powered search experience that synthesizes answers from indexed data.
- Programmatically manage Discovery Engine datastores, schemas, and configurations from Python applications.
- Implement multi-turn conversational search with grounding in custom knowledge bases.

Install
google-cloud-discoveryengine on PyPI
Before you install
Low friction installation with a pure Python wheel. Actively maintained with a recent release; last commit 2026-08-14. Depends on standard Google Cloud libraries (google-api-core, google-auth, grpcio, proto-plus, protobuf, grpc-google-iam-v1), all widely used and stable.
Requires Google Cloud project with Discovery Engine API enabled, billing configured, and valid authentication credentials (typically via GOOGLE_APPLICATION_CREDENTIALS environment variable or Application Default Credentials).
License in practice
Apache-2.0 permissive license allows commercial use, modification, and distribution with minimal restrictions. Suitable for most projects, whether proprietary or open-source.
