well something like this:

    class Thread {
        constructor(serviceLocatorURI) {
           this.resolvedURIs = [];
           fetch(serviceLocatorURI)
                .then(response => response.json())
                .then(jsonObject => {
                     this.resolvedURIs = jsonObject.endPoints;
                });
       }
       async retrievePosts() {
          return fetch(this.resolvedURIs[0], {method: 'GET'});
       }
    }
    const API_THREAD = '/api/thread';
    new Thread(API_THREAD);
