What this server can do
5 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
create_checkout(lang, email, sku_or_id)- Create a secure Stripe payment link for an ALT eSIM plan. Returns a payment URL the BUYER opens to pay (the agent never handles card details) AND a checkout_session_id. After the buyer pays, call get_qr_code with that checkout_session_id to fetch the eSIM QR and show it to the buyer. The QR is also emailed. Charged in USD. You MUST collect the buyer's real email. Required: sku_or_id, email.
get_esim_plan(sku_or_id)- Get one ALT eSIM plan by its sku or id. Returns full details: title, data amount, validity days, USD price, coverage carriers, product URL. Required: sku_or_id.
get_qr_code(checkout_session_id)- Fetch the eSIM QR code(s) for an order, to show the buyer directly. Pass the checkout_session_id from create_checkout. Returns a clear `status`: 'awaiting_payment' (buyer has NOT paid — tell them to pay), 'processing' (paid, eSIM still provisioning — retry in ~30s), 'ready' (returns the QR image(s) + ICCID(s) to display), 'expired', 'refunded', or 'failed'. Use the status to tell the buyer exactly what's happening — never assume payment succeeded. Required: checkout_session_id.
list_destinations- List all ALT eSIM destinations (country/region slugs with English names and region). Use a slug as the 'country' argument for search_esim_plans.
search_esim_plans(region, country, max_price_usd)- Search ALT eSIM travel data plans. Filter by destination country slug (e.g. 'japan', 'usa', 'europe'), region, and/or max USD price. Returns plans with sku, data amount, validity days, USD price and coverage carriers. All prices are USD.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
