Hopwell for AI agents
An assistant planning a trip can look up plans here and start an order. The traveller pays by card through a link and gets the eSIM by email.
Sales open soon. Until then the price list is live and an attempt to start an order is answered with "Sales are not open yet."
What an agent can do
- Read every plan and price, for 145 countries and the regional plans.
- Start an order for up to six plans and get a Stripe payment link back.
The agent doesn't pay and never sees the eSIM. The person opens the link, pays by card, and the QR code and install steps go to the email address they enter there. The page they land on after paying only confirms the order, so a link that passed through a conversation opens nobody's eSIM. No key or account is needed for any of this.
Connect over MCP
The address is https://hopwell.app/api/mcp/. It speaks the Model Context Protocol over HTTP and keeps no session.
In a client that reads a JSON config:
{
"mcpServers": {
"hopwell": { "type": "http", "url": "https://hopwell.app/api/mcp/" }
}
}| Tool | What it does |
|---|---|
find_plans | Plans and prices for a country or region, with the regional plans that cover it. |
create_checkout | Starts an order and returns the payment link to give the traveller. |
become_partner | Signs someone up to the partner programme and returns their link. |
Or plain HTTP
The whole price list is one file: https://hopwell.app/plans.json. To start an
order, send the ids, sizes and days exactly as that file lists them:
curl -X POST https://hopwell.app/api/checkout/ \
-H "content-type: application/json" \
-d '{"items": [{"id": "japan", "gb": 5, "days": 30}]}'
{"url": "https://checkout.stripe.com/c/pay/..."}Prices are in US dollars and are set by us, never by the request. The link stops working after 24 hours.
Before sending someone to pay
- The phone has to support eSIM and be carrier-unlocked. The check takes ten seconds.
- Plans are data only, with no phone number, paid once. Nothing renews.
- We can't sell to buyers in the United Kingdom or India yet, or in countries under US sanctions. A payment from one of those is refunded automatically.
- The refund policy is the same as for any order.
Earn on the orders you start
Join the partner programme and pass your code as ref, in
create_checkout or in the body of the HTTP request, and 15% of the order is yours. You can
also put it in the address you give an MCP client: https://hopwell.app/api/mcp/?ref=your-code.
