Your challenge
Trading platforms need more than just price feeds to provide a complete trading experience.

From basic company information to complex corporate actions, reference data forms the critical foundation that makes trading possible. Yet developers often struggle with fragmented data sources, inconsistent formats, and complex enterprise APIs. While price feeds are readily available, the contextual data that makes trading possible is often scattered across multiple providers, buried in enterprise APIs, or hidden behind complex integration processes. Development teams typically face a difficult choice: either integrate multiple enterprise-grade APIs with their overwhelming complexity and cost, or spend precious time to build their own data infrastructure from scratch.
