I am getting the following error when trying to simply create the API and list the price of item 19718 it works but throws this error at start. https://paste.gg/p/anonymous/d6edae1aa36542e08bfd0d58dcbde8f4
Java Verison: OpenJDK 18

Sorry to hear that! I am not sure what the problem is but it does not surprise me that something had to break at some point considering how old the libraries are.
I assume you have already tried the recommendations from a quick search like adding

    <dependency>
      <groupId>javax.activation</groupId>
      <artifactId>activation</artifactId>
      <version>1.1.1</version>
    </dependency>

or overriding the Jersey version with a newer one like

<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.37</version>
</dependency>

I began a rewrite many months ago but I never finished it. I got relatively far and might have something ready for you relatively quickly if you need it. Though, some existing endpoints would be missing then.
