Building an eSIM supply API for apps, looking for 10 early feedback users
I’m working on an eSIM supply API for apps that want to show eSIM data plans as a product inside their own flow.
The basic idea is simple: instead of every app figuring out country plans, validity, data limits, activation/QR delivery, order status, failed activations and provider differences by themselves, we expose it as one supply layer that an app or agent can call.
The part I’m most interested in is making it agent-native. So not just a normal catalog API, but something where an AI travel agent, support bot, booking app or marketplace can search plans, compare options, create an order, and explain the next step to the user without needing a human to understand every provider rule.
I’m looking for around 10 people who are building travel apps, AI agents, marketplaces, travel communities, loyalty products, or anything where showing eSIM/data plans inside the app would be useful.
No signup link yet. Just looking for honest feedback on the API shape, what fields you’d need, and what would make this actually useful instead of another generic telecom API.
If this is relevant to what you’re building, comment or DM and I’ll share the rough API flow.
