API-first solutions for stocks and crypto #

Whether you are launching an app to access the US equities market or deploy algorithmic trading-strategies with stocks and crypto, Alpaca has an API for you.
If you are not a developer and an API is not for you, we also enable users to trade on our web dashboard and mobile app.
