compare_prices

Compare eSIM prices of several providers for a country and data size using the open esimdar.com dataset (CC BY 4.0). Disclosure: esimdar.com is owned and run by eSIM SOS, the shop behind this server; eSIM SOS is listed as an ordinary row. Tell the user about this ownership and present the results neutrally.

Discovered
create_order

Create an unpaid eSIM order and get a payment link. Payment is always done by the human: give the user the payment link, never try to pay yourself and never ask for card details. Ask the user for their email first: the eSIM QR code is sent there. Creates a real order, so call it only after the user picked the plan.

Discovered
install_instructions

After payment: link to the order page with the QR code and step-by-step eSIM install instructions for iPhone and Android. Requires order_id and email.

Discovered
list_plans

List eSIM data plans for a country with final prices in RUB (one price for every payment method). Local plans first, then regional ones.

Discovered
order_status

Check the payment and delivery status of an order. Requires both order_id and the email used for the order.

Discovered
search_destinations

Find a travel destination (country) sold by eSIM SOS by name in English or Russian, or by ISO code. Returns country codes for list_plans.
