Introducing the Alpaca Paper Trading API

In our continuous effort to make automated trading more accessible, we are pleased to announce the Alpaca Paper Trading API to allow more people to easily try our API. The Alpaca Paper Trading API will be free to use and will be open to anyone globally. You don’t need to open a brokerage account to use the API.

Key Benefits

  • No need for a brokerage account to use the API
  • No requirement to be a US resident to use the API
  • Unlimited testing of your algos and bots for free
  • No limitation in setting the paper account balance
  • Switch to live-trading with exactly the same code (live-trading and securities are offered through Alpaca Securities LLC)

Data API Beta Launch

As a part of this release, we are also launching Data API Beta.

Data API is a suite of API that aims to be the next level of market-related data support. We provide an alternative endpoint to support multi-symbol query for price data called Bars through this Data API. As of today, Data API Bars supports IEX minute-level price and daily price data, but we plan to add features and data coverage over the time. Please read the Market Data section in our documentation for more details.

Python SDK

Our official Python SDK with the Data API support has been released, and other language SDKs follow soon. No existing functionality changes at this point and your API calls will continue to work unless we announce otherwise in the future.
