Not yet, but the idea of a data vending machine, or something like it, is going to be of vital importance, I think.
I’m in the process of putting together a series of bounties to refactor DCoSL with better design and UX to give it better visibility. Trying to decide if rebuilding it as a web app (instead of a desktop app) is the way to go. You could go to the site, pick a list, pick a reference user, and observe which list items are accepted vs rejected by the reference user’s web of trust. The key observation would be that list curation by Alice’s WoT != list curation by Scammy Joe’s WoT.
So then I think: maybe add an API, so your client could request the crowdsourced list of High Quality Writers (or notes) on Topic X (query contains the event ID of the list and the pubkey of the reference user) and get back the crowdsourced list of pubkeys (or note event IDs). And maybe charge some sats to use the API.
Ultimately, the idea of a data vending machine may be better, if I understand the idea correctly, bc the sats are going to a user (the one ultimately responsible for the curating) rather than to a website.
