Built this dashboard to visualize cannabis sales in real time across North America during 4/20. The data updates live from thousands of dispensary POS transactions as the day unfolds.

Under the hood, we’re using Estuary for data streaming and Tinybird to power super fast analytical queries. The charts are made in Tremor and the map is D3.

How did you get access to the data?

Hello OP, do you work for sales? So much bluster in your site but so little substance in this answer.

Is there a law mandating realtime reporting, or something, or are there just limited number of POS providers and they all have realtime API(s)?

I bet the dashboard doesn't have Johnny from my street corner's transaction...

Not sure what more substance you need, we integrate with close to 30 different POS providers, that's it. There is no law mandating realtime reporting. Every transaction from thousands of retailers is represented... What more do you want to know?

This is a better answer. "Point of sale APIs" is as clear as "we get the data in JSON format", i.e. not answering the question at all.
