Modern API to Build Your Own Commission-Free Trading Services
With Alpaca's RESTful Web API, you can build apps and services that let your users buy and sell U.S. stocks with zero commissions through Alpaca Securities LLC, a technology-driven FINRA-registered broker-dealer.
Commission-Free trading means that there are no commission charges for
Alpaca self-directed individual cash brokerage accounts that trade U.S. listed
securities through an API. Relevant SEC and FINRA fees may apply.
