Commission-free trading, algorithmic investment strategies, embedded finance, and cryptocurrency integration are no longer optional—they're competitive necessities.

The Complexity of Financial API Integration
Alpaca offers powerful APIs for trading stocks, ETFs, options, and cryptocurrency. However, building production-ready financial applications requires far more than just calling API endpoints. Developers must understand order types and execution strategies, margin calculations and risk management, regulatory compliance (SEC, FINRA, SIPC), market data licensing and processing, fractional share mechanics, OAuth integration for connected apps, real-time websocket data streams, and settlement and clearing workflows.
Critical Development Challenges:
Teams without financial services experience struggle with implementing proper order validation and risk checks, handling market volatility and circuit breakers, processing real-time market data at scale, managing user authentication and authorization securely, calculating accurate portfolio valuations, implementing compliant KYC/AML workflows, reconciling trades and settlements, and debugging production trading issues under time pressure.
