Case Study: an international financial intelligence provider reduces research API complexity with Expert Soft

International Financial Intelligence Provider splits one overloaded API into three with Expert Soft

The international financial intelligence provider faced challenges with an overloaded Research API that had accumulated business-specific logic for multiple product lines, making it complex to maintain and risky to change. Expert Soft was engaged to split this shared service into focused APIs to reduce cross-business impact and improve maintainability.

Expert Soft successfully split the single service into three independent APIs, each aligned with a specific business line. This solution separated business-specific filters and response logic, introduced a token-based system for stable retrieval of large document sets, and standardized error handling. The results included clearer service boundaries, a lower risk of changes impacting other business units, and stable access to thousands of research documents for downstream systems.
