I'd actually find it pretty cool to get access to my own level 3 data for smarter budgeting/analysis (eg: automatic tracking of food stocks, separation of spend on luxury foods from basics etc), but I've not found a way to get access as an individual yet

But Level 3 data includes each individual line item:

8/11/2024 | Amazon.com | $50 | 1 Very Embarrassing item | some additional fields

This appears in all sorts of interesting ways, and is not restricted to B2B/B2G transactions as they state so prominently. Anyone can sign up if they have a certain number of transactions per year and save quite a bit on credit card processing fees for providing the data.

I can't find the article but there was a tire company that provided a branded credit card, and they had risk profiles for their customers. The riskiest went to some specific bar, and the least risky were buying snow removal tools. (Please forgive my memory if I have the details incorrect).

"Martin’s measurements were so precise that he could tell you the “riskiest” drinking establishment in Canada — Sharx Pool Bar in Montreal, where 47 percent of the patrons who used their Canadian Tire card missed four payments over 12 months. He could also tell you the “safest” products — premium birdseed and a device called a “snow roof rake” that homeowners use to remove high-up snowdrifts so they don’t fall on pedestrians."

Additionally if you try to buy large amounts of visa gift cards it can be problematic. This is one way they catch manufactured spend.

At the end of the day, some merchants are providing every single detail of your transactions down to the line item and all that information is being tagged to you.
