I am looking for a Patreon-like service where patrons could pledge money to individual pieces of content. Imagine that I create and maintain a public transport map for each city in the world and I want to let locals to pledge to their local city map. Something like that. Ideally with a donation counter that I could embed into each individual map. Of course, there are thousands of cities so I will need an automated way (API) to create individual wallets. Does such service exist?
