Alpaca

Alpaca is a developer-first API brokerage platform and a fully registered, self-clearing US broker-dealer. Their mission is to open financial services to everyone on the planet. Instead of building a flashy consumer trading app like Robinhood, Alpaca built the underlying infrastructure. They offer powerful, modern APIs that allow algorithmic traders, hedge funds, and global FinTech startups to instantly build customizable investing applications. Whether a developer wants to write a Python script to automate their own stock trades, or an international startup wants to offer US stock investing to its users in Latin America or the Middle East, Alpaca provides the complete backend infrastructure to make it happen.
