Python client for the Polygon.io API.

pip install polygon-api-client

Requires Python >= 3.8.

See the Getting Started section in our docs or view the examples directory.

For now, we're generally not accepting pull requests from outside contributors but we're open to bug reports and feature requests. Or if you have more general feedback, feel free to reach out on our Slack channel.

This client will attempt to follow the release cadence of our API. When endpoints are deprecated and newer versions are added, the client will maintain two methods in a backwards compatible way (e.g. list_trades and list_trades_v4(...)). When deprecated endpoints are removed from the API, we'll rename the versioned method (e.g. list_trades_v4(...) -> list_trades(...)), remove the old method, and release a new major version of the client.

The goal is to give users ample time to upgrade to newer versions of our API before we bump the major version of the client, and in general, we'll try to bundle breaking changes like this to avoid frequent major version bumps.

Exceptions to this are:

• Methods under client.vx. These are expiremental.
• Methods that start with _*. We use these internally.
• Type annotations. We may modify these based on our JSON responses.
• We may add model fields.
