eSIM Tabby

Cancel an order and refund it. Only possible while the eSIM is uninstalled. Once the profile has been installed on a device the provider refuses to take it back, and this returns an error instead — send the user to support. Card payments refund automatically. A USDC payment has no on-chain refund rail, so the order becomes `refund_pending` and support returns the money by hand.

Start a purchase — the step after the user picks a plan from search_esim_plans. Call it with that plan's plan_id (get_plan_details shows the current price first). Returns an order_id and where to pay, on the rail you asked for: 'card' (the default) returns a checkout_url — a hosted Stripe page for a human to open in a browser; once they say they've paid, call get_order_status to confirm and carry on to the QR code. 'x402' returns an x402_url for a wallet to settle in USDC, with no browser step — only choose it if you actually hold a wallet. Never accepts payment details — a card is entered on the hosted page, and a wallet signs for itself. Calling it again for the same plan reuses the pending order (reused: true) instead of creating a duplicate.

Buy more data for an eSIM the user already has — the step after list_topup_options. Call it with the order_id of the fulfilled eSIM and a plan_id chosen from list_topup_options. The top-up lands on the existing eSIM: same QR code, nothing to re-install. Returns a new order_id and where to pay, exactly like create_checkout: 'card' returns a checkout_url for a human to open, confirmed via get_order_status; 'x402' returns an x402_url for a wallet to settle in USDC. Never accepts payment details — a card is entered on the hosted page, and a wallet signs for itself.

Get the QR code and activation details for a purchased eSIM. Not read-only: like get_order_status, an order that is not ready yet is advanced first, so this can change the order's state.

How much data an active eSIM has used, and how much is left.

Check an order. Call this after the user says they've paid. Not read-only: an order still in progress is advanced first — payment is confirmed and the provider order placed or collected — so the status can change as a result of calling this.

Full details of one eSIM plan, including current price.

List this account's eSIM orders, newest first.

Data top-ups that can be added to an eSIM the user already has. A top-up extends the existing eSIM — same QR code, nothing to re-install. Not every plan is reloadable; this returns an empty list when none apply.

Pay for an order in USDC over x402, without opening a browser. Only for an MCP client that signs x402 payments itself: call it once for the payment requirements, then repeat the call carrying the signed payment in _meta['x402/payment'] and it settles and starts the eSIM. If your wallet is a separate tool, make an x402 request to the order's x402_url instead — this tool cannot take a payment on a wallet tool's behalf.
