Current Issue and Customer Impact
Market Data API v1 was deprecated on September 26, 2021. On March 15, 2022, all Market Data API v1 endpoints and documentation will officially sunset.
In order to continue providing the best experience for users, we are only supporting Market Data API v2, the second version of the Market Data API. Market Data API v2 provides market data in two different plans, Free and Unlimited. The Free plan is included in both paper-trading and live trading accounts as the default plan.
Solution and Breaking Change
Customers will need to update any existing systems to use the Market Data API v2 endpoints. Any system still using Market Data API v1 endpoints will result in a break in code when the API version officially sunsets in March.
Client libraries will no longer support Market Data API v1 in any new client library versions after the sunset date.
Timeline
Market Data API v1 endpoints will sunset on March 15, 2022 and will be removed from the Alpaca documentation. After March 15, 2022, systems using v1 endpoints will no longer work.
