So,the api provider, like stripe, is supposed to publish a second API?

And then the "end developer" who is going to be making a chatbot/agent, is supposed to use that to make a chatbot?

Why does the plan involve there being multiple third party developers to make n products per provider? If the plan is to have third parties be creative and combine, say, Stripe with Google Ads, then how is a second API for LLMs useful.

I'm not seeing the vision here. I've seen something similar in a project where a guy wanted LLM developers to use his API for better browsing websites. If your plan involves:

1- Bigger players than you implementing your protocol 2- Everybody else doing the work.

It's just obviously not going to work and you need to rethink your place in the food chain.
