Scored across 9 tools
Each tool has a clearly distinct purpose: destination/plan discovery, payment coin lookup, order creation/cancellation/status, and top-up lookup/creation. create_order vs create_topup and list_plans vs list_topups are distinguishable from their descriptions.
All tools follow a consistent snake_case verb_noun pattern: cancel_order, create_order, create_topup, get_order, get_plan, list_payment_coins, list_plans, list_topups, search_destinations.
Nine tools is well-scoped for an eSIM purchase and top-up workflow. Each tool supports a concrete step without obvious redundancy.
The core lifecycle is covered: discover destinations, inspect plans, choose payment coins, create and poll orders, cancel unpaid orders, and top up existing eSIMs. Minor gaps include no order history/list-orders operation and no direct eSIM lookup/status tool outside of an order response.
Cancel an unpaid order the person decided not to pay. Do not cancel after the payment was sent.
Inputs: order_id (required), order_token (required).
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, the exact amount and the address. The person must send exactly that amount on that network before expires_at. Then poll get_order. Unpaid invoices per client are limited; cancel unused ones with cancel_order.
Inputs: coin (required), plan_id (required), ref, network, +2 more.
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.
Inputs: coin (required), iccid (required), plan_id (required), network.
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.
Inputs: order_id (required), order_token (required).
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.
Inputs: plan_id (required).
Coins and networks accepted for payment. Pass coin and network to create_order. Sending on a different network loses the funds.
Inputs: no named parameters.
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 number; the UK number plan must be installed only after arrival in the UK. For a country without its own plans, regional and world plans that cover it are returned. Prices are final USD prices; the crypto amount is set at create_order.
Inputs: destination (required), type, include_regional.
Check whether an installed Cypher eSIM can be topped up and list the plans that can be added to it.
Inputs: iccid (required).
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.
Inputs: limit, query.
