What are Financial Data APIs for iPhone?

Financial data APIs are application programming interfaces that provide developers and businesses with real-time or historical financial data, such as market prices, economic indicators, company fundamentals, and transaction records. They allow seamless integration of financial information into applications, dashboards, analytics platforms, and trading systems using standardized request/response protocols. These APIs often include features like authentication, rate limiting, and data formatting to ensure reliable and secure access to data from exchanges, banks, or data providers. Many financial data APIs support multiple asset classes, including equities, fixed income, commodities, FX, and crypto, enabling broad use cases across fintech and enterprise software.
