Best Market Data APIs: Zyla API Hub vs API Marketplace by AWS 2025

Zyla API Hub and the API Marketplace by AWS. We will delve into the features, capabilities, and advantages of each platform, highlighting why Zyla API Hub may be the superior choice in 2025.

Understanding the Need for Finance APIs

• Data Inaccuracy: Manually sourcing financial data can lead to errors and outdated information.
• Time Consumption: Building a custom solution for data retrieval is time-consuming and resource-intensive.
• Integration Complexity: Integrating multiple data sources can create a fragmented system that is difficult to manage.

Overview of Zyla API Hub and AWS API Marketplace

Zyla API Hub offers a unified platform for accessing multiple APIs, simplifying the integration process for developers. With a single account, users can access a variety of finance APIs, including currency conversion, interest rates, and investment calculations. In contrast, the API Marketplace by AWS provides a broader range of APIs but lacks the streamlined integration experience that Zyla offers.
