Data Commons Python Client API

This is a Python library for accessing data in the Data Commons knowledge graph. To get started, install this package from pip.

You will also need to provision an API key by enabling the Data Commons API on GCP. Once you have the API key, simply add the following line to your code.

After you're ready to use the API, you can refer to datacommons/examples for examples on how to use this package to perform various tasks. More tutorials and documentation can be found at tutorials!
