Market Exchange Details API - Finnworlds

The Market Exchange Details API provides structured JSON data about global trading venues and their reference identifiers. Get complete identification data for any exchange MIC, including operating MIC, market segment, status, legal entity information (LEI), location, status and official website. With a single API call, you can resolve an exchange’s identity and metadata for compliance, routing, and display needs.
