## Tools (as reported by the server, not verified)

- `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`: 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.
