get_esim_plan

Get one ALT eSIM plan by its sku or id. Returns full details: title, data amount, validity days, USD price, coverage carriers, product URL.

Parameters (1)

sku_or_idstringrequired
The plan sku (e.g. 'eSIM_Alt_JP_1DG1') or id.

create_checkout

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.

Parameters (3)

sku_or_idstringrequired
The plan sku or id to buy.
emailstringrequired
Buyer's email — the eSIM QR code is also sent here.
langstring
Delivery email language (default 'en').

get_qr_code

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.

Parameters (1)

checkout_session_idstringrequired
The checkout_session_id from create_checkout (Stripe session id).
