Tools as reported by the server

• search_destinations
  Find a country, region or "world" destination by name or ISO code. Returns destination codes for list_plans (country: ISO2 like "JP"; region: like "R-EUROPE"; world: "WORLD"), starting prices in USD, and how many data and phone-number plans exist. An empty query lists all destinations.
• list_plans
  List purchasable plans for a destination, cheapest first. type "data" = data-only eSIM: validity starts on first connection at the destination. type "number" = eSIM with a phone number, calls and SMS: validity starts at installation, so install it just before use; Europe plans give a French +33 numb
• get_plan
  Full details of one plan: all covered countries, data, days, phone number (if any), install rules, when validity starts, and notes. Read the notes to the person before create_order.
• list_payment_coins
  Coins and networks accepted for payment. Pass coin and network to create_order. Sending on a different network loses the funds.
• create_order
  Create a crypto invoice for one new eSIM. Before calling, confirm the plan with the person and tell them when validity starts and the plan notes (number plans: validity starts at installation; Europe number is French +33; UK number plan: install only after arrival). Returns order_id, order_token, th
• get_order
  Order status: pending (waiting for payment), paid (issuing), delivered, expired, failed. When delivered, returns for each eSIM: QR code (also as an image), LPA activation code, ICCID, and one-tap iOS/Android install links. Call at most once every 5 seconds.
• cancel_order write/delete
  Cancel an unpaid order the person decided not to pay. Do not cancel after the payment was sent.
• list_topups
  Check whether an installed Cypher eSIM can be topped up and list the plans that can be added to it.
• create_topup
  Create a crypto invoice that adds a data plan to an existing eSIM (no new QR, nothing to install). plan_id must come from list_topups for this ICCID. Payment and polling work exactly like create_order.
