I’m working on a decentralized marketplace and for now, we tap into the store’s e-commerce platform API to get the inventory, handle cart creation, etc.
I commend you for trying to start a standard. Letting the established players establish standards and protocols just gives them a bigger moat and more influence.
Pay very close attention to e-commerce and conversational commerce, rent seekers are pushing protocols.
APIs are toll roads. If you need an API key just to read a price, it is not the Open Web. It is a walled garden. We designed this to be permissionless. A text file has no gatekeeper. It bypasses the rent seekers entirely. The standard must belong to the commons, or it becomes just another extraction layer. Keep fighting the good fight.
