Searches, purchases, manages, tops up, and cancels travel eSIM data plans, with activation details, usage checks, and card or USDC payment options.

Tools
cancel_order
Cancel and refund an order
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 â 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.

create_checkout
Start a purchase
Start a purchase â 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 â 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 â only choose it if you actually hold a wallet.
Never accepts payment details â 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.

create_topup_checkout
Buy more data
Buy more data for an eSIM the user already has â 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 â a card is entered on the hosted page, and a wallet
signs for itself.

get_esim_activation
Get eSIM activation QR code
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.

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

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

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

pay_order
Pay for an order in USDC
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 â this tool
cannot take a payment on a wallet tool's behalf.
