RESTful APIs and real-time APIs provide programmatic access to market data, trading functions, and analytical services. Financial APIs support various use cases including algorithmic trading, portfolio rebalancing, compliance monitoring, and client reporting.

Cloud-based APIs enable scalable access to financial services without requiring extensive infrastructure investment. API economy in finance continues growing as firms seek to integrate best-of-breed solutions and enable digital transformation across their operations.
