About xChangeApi

xChangeApi provides real-time currency exchange rate data through a REST API and a WebSocket API. The REST endpoint returns exchange rates against a base currency in JSON, XML, or CSV format, while the WebSocket connection streams live rate updates for subscribed currency pairs with sub-second latency over a secure WSS connection. The service also offers historical exchange rate data across various time intervals and aggregations.

The API covers major global currencies and popular cryptocurrencies, with authentication via API key and HTTPS-only communication. Documentation includes code examples in 8+ languages, and a 7-day free trial is offered to new users.

This service is aimed at developers building financial applications such as trading platforms, live dashboards, and other tools requiring real-time or historical currency exchange data.
