Anyone have recommendations for building a custom AI agent that lives behind a paywall?

I’m looking for the simplest solution that allows:

1. Training a model on my own content (courses, podcast archive, etc)

2. Paywalled access, ideally accepting both fiat and crypto

Everything I’ve explored so far requires landing pages, third-party integrations, or complex stacks that feel like overkill (and cost). I just want to get it live without duct-taping tools together.

Would love to hear what’s working for others. 🙏

I believe you can monetize Custom GPTs directly on OpenAI or at least that was the plan.  

You can absolutely train one on your own content and then share it if the monetization isn't built in yet.

If not, I bet you could wire up something maybe with n8n or the like and just put a stripe or supabase paywall in front of the page.

can't use custom gpts on the api, which is so dumb, would happily pay a little extra per call to not have to rebuild useful ones
