  • Historical exchange rates are now updated every 100 milliseconds (previously every 1 second)
  • This change applies to all currency pairs in our historical data set
  • No action is required from customers to access this enhanced data

  • Exchange-Specific Connections: The new setup ensures that issues with one exchange do not affect other data streams.
  • Direct Routing with Optimized DNS: Connections are routed directly to the infrastructure closest to the exchange, reducing latency by eliminating unnecessary hops and aggregation points.
  • Enhanced Authorization: Authorization now supports query-string, URL path, header, or JWT (JSON Web Token), removing the need for the API key field in the hello message.
