Simple console app which looks up supplier parts by MPN
You need an application at nexar.com with the Supply scope.
Use the application client ID and secret and set environment variables NEXAR_CLIENT_ID and NEXAR_CLIENT_SECRET.
Each of these examples are using a "nexarClient" or "supplyClient" class. This class provides the necessary functionality to retrieve tokens and then use them to query the API. Then there are example runnable files that use this client to perform a given query and then display the data.
