Today's financial industry needs to secure, flexible, reliable and immediate access to vast quantities of intricate information. Exposing data products as APIs is a powerful methodology to foster self-service access to data across inter- and intra- organizational perimeters. This paper discusses the architecture, security and governance practices, schema design, performance management and operations of financial data products as GraphQL APIs. The design choices and the implementation processes are supported by real-life examples, describing their advantages and their drawbacks. Future prospects are outlined in the fields of AI-based query understanding and optimization, privacy-preserving computations and other innovative practices that will determine the architectural blueprint of next-generation API-based financial data products
