Paid memberships are now available in Swarm (https://swarm.to). Please see changelog entry here: https://swarmto.canny.io/changelog/set-up-paid-memberships

Customers may already be using solutions for selling memberships and one-off purchases and storyprompt may just be an augmentation (i.e. for a particular YouTuber or for an Agency's client). If you're planning to create the payment platform please also support just a way of granting access to the platform capabilities by particular uses via the REST API, then users of existing membership solutions can just add a StoryPrompt space, for example, and then use the StoryPrompt API to give "john doe" access to this space.
