I have been working on https://www.accessmrf.com - a catalog of all American health care prices. Since there's way too much data, I am building a taxonomy and deduplicating it extensively first, with the idea that I can shrink it by ~4 orders of magnitude and make the problem tractable. I have written a bit about how I do it here: https://www.felixhaba.com/writing/simplifying-healthcare-pri...

My goal this week has been to index all insurers that publish machine readable files. For now, my project helps researchers and founders in the space access the data via API, it is not consumer-grade yet. But if you are interested in this data I would love to brainstorm ideas or share my knowledge. Shoot me a message.
