What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

• 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 destina

• 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 gi

• 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

• 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

  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.
