Yes - Public Business Accounts get free access to the Public API for trading stocks, ETFs, options, index options, bonds, and crypto. There's no cost to generate an API key or make calls, and the API supports fractional shares and extended hours trading (up to 24 hours a day, five days a week for eligible U.S. equities).
Note: API access itself is free, but standard trading costs still apply depending on asset class - for example, index options carry a per-contract fee, crypto trades are priced on a volume-based schedule, and bonds carry a per-$100 fee. Stock, ETF, and single-leg equity options trades carry $0 commission (options trades still pass through required regulatory fees). See our full fee schedule for a complete breakdown.
