Valuations change daily (market dependent). Do not cache valuation responses for more than 24 hours. However, static technical specs (engine size) can be cached permanently.
Dealers use the API to instantaneously generate "part-exchange" valuations. When a customer arrives with a used car, the salesperson enters the license plate; the CRM calls the Eurotax API and displays the trade-in value within two seconds—preventing human error or low-ball offers.
Eurotax services are generally delivered through RESTful web services.
