Are there any details on how bp.tf gets its market data?

Question is pretty self-explanatory. Googling around for 'community market API' gives no results except one person who found how to generate the JSON embedded in HTML and another who said doing anything with the market is against ToS.

 

Before I get flooded, I'm *not* here to ask how to make an automated ripoff bot or anything stupid, nor am I making my own bp.tf or anything crazy. Just asking for information about how to find the market API (since bp.tf obviously does)

Ah, that makes sense. I've been googling around 'steam community market API' and been getting nothing. And then I guess this is just left to run for a while to build a sample size?

 

Thank you!
