Alpaca Securities LLC is a financial technology startup that operates in the stock brokerage industry. It is a member of the Financial Industry Regulatory Authority (FINRA) and the Securities Investor Protection Corporation (SIPC), ensuring its credibility and security. Alpaca's primary offering is an API-first brokerage service, which allows other businesses to build their own trading applications using Alpaca's infrastructure. This eliminates the need for these businesses to become brokers themselves, saving them significant time, development, and legal resources.

Alpaca's clients are primarily other businesses, such as InvestSky and Woodstock, who want to offer their own customers the ability to trade stocks. Alpaca's API allows these businesses to integrate stock trading functionality into their own applications, providing a seamless experience for their users. Alpaca also offers Local Currency Trading API, which simplifies the trading experience for international investors by allowing them to trade US stocks in their local currency without needing to convert to US dollars.

In addition to its brokerage services, Alpaca also offers crypto wallets and coin pair trading with BTC, USD, USDT, and USDC pairs. This allows users to deposit, withdraw, and trade cryptocurrencies, further expanding the range of financial services that Alpaca's clients can offer to their own customers.

Alpaca makes money by charging fees for its services. These fees are likely based on the volume of trades executed through its platform, although the exact pricing model is not specified.
