TW Shop Items Cache
This part of the Data Warehouse provides for each world a list with all towns and its shop items. If you need it for scripts, use
https://tws.webspace.rocks/shops/?worldId=IDENTIFIER to gain the data.
The cache header will keep the data for 24 hours, so it won't be a long wait after the initial request.
The shops get crawled if the following statement is fulfilled:
    (worldId % 20 + 3) != UTC.currentHour
To identify the world use that snippet. As it provides the local code and the ID.
