How did they manage to get access?
Or do you need to get an API key first?
I don't think they have any access or scraped data. The plugin let's me configure a JLCPCB DB path and it seems like it doesn't ship with one. I have no clue how to obtain that db.
I think there are some github repos that scrap LCSC components and expose them as an API.

Seems to be scraped data? and then you review it manually like it recommends in: https://github.com/mixelpixx/Konnect/blob/9488e5f09717cb508c...
