 # Massive (formerly Polygon.io) Python Client - WebSocket & RESTful APIs
 
-Welcome to the official Python client library for the [Massive](https://massive.io/) REST and WebSocket API. To get started, please see the [Getting Started](https://massive.io/docs/stocks/getting-started) section in our documentation, view the [examples](./examples/) directory for code snippets.

To get started, please see the [Getting Started](https://massive.com/docs/stocks/getting-started) section in our documentation, view the [examples](./examples/) directory for code snippets.
 
 **Note:** Polygon.io has rebranded as [Massive.com](https://massive.com) on Oct 30, 2025. Existing API keys, accounts, and integrations continue to work exactly as before. The only change in this SDK is that it now defaults to the new API base at `api.massive.com`, while `api.polygon.io` remains supported for an extended period.

-The free tier of our API comes with usage limitations, potentially leading to rate limit errors if these are exceeded. For uninterrupted access and to support larger data requirements, we recommend reviewing our [subscription plans](https://massive.io/pricing), which are tailored for a wide range of needs from development to high-demand applications. Refer to our pricing page for detailed information on limits and features to ensure a seamless experience, especially for real-time data processing.
