2.5 Data Mining. You may not intercept, mine or otherwise collect information from the Game using unauthorized third party software.
So by the reading of that, yes it's in breach of ToS. As is any non-endorsed fansite that has an item database, as is entering item information into a spreadsheet for personal use, as is emailing a friend the stats on that item you just got. Streaming to twitch or recording to YouTube would also be a breach unless they've officially endorsed either services.

Sounds ridiculous? It is, it's overly general by design, as are most ToS. As a result you will probably not receive an answer on this.

What most all ToS can be broken down to is this:
1. We can stop your service at any time for any reason we choose without giving you a refund for past services received and possibly future services purchased.
2. If you take us to court, our ToS will likely fall apart and you will receive a full to partial refund that which will most definitely be less than your cost of litigation.
3. Even if you receive a refund, you will no longer be receiving services from us.
