Tools

• buy Moves money · ~183 tokens
  Get the x402 payment challenge for a quote. This hosted server holds no wallet, so it does NOT spend your money: it returns the exact amount, asset, payTo address and facilitator for you to pay from your own Algorand wallet, then you POST the quote again with your payment signature. Requires prior h
• create_pay_link Moves money · ~400 tokens
  Create a checkout link a HUMAN pays from their own Algorand wallet (Pera). Use this when you have no wallet, or when the person should approve and pay themselves: they open the link, see the exact price, sign in their wallet, and the result (the eSIM QR code, or the top-up confirmation) appears on t
• fx ~147 tokens
  Indicative USDC → local-currency rate at our sale price, with an estimate for an amount. The quote is the binding price.
• ledger ~65 tokens
  Public delivery ledger: totals, delivered-or-refunded %, volume, countries, recent orders.
• list_offers ~245 tokens
  Browse purchasable offers: mobile top-ups, travel eSIMs, prepaid bills, or international payment corridors (bank / mobile money / UPI) for a country. Free. Prices shown are indicative; the quote fixes them.
• lookup_phone ~204 tokens
  Identify the country and mobile operator of a phone number and list the top-up offers available for it. Free. The operator is DETECTED from the number range and is a guess: MVNOs (Tesco Mobile, Giff Gaff, Lebara, Voxi, Sky…) resolve to the host network they ride on. Read the detected brand back to t
• order_status ~100 tokens
  Check an order. Poll every ~3 s until `terminal` is true: delivered (confirmation + signed receipt), refunded (refund txid + signed receipt) or refund_failed.
• quote ~441 tokens
  Lock a price (10 minutes) for one purchase. Returns quoteId, exact USDC price and what will be delivered. Free. ALWAYS show the human the price and the recipient before buying.
• quote_vouchers ~342 tokens
  Lock a price (10 minutes) for a BATCH of travel eSIMs paid in one payment: N claim links, one per person, for a group trip, a conference delegation or event giveaways. Each eSIM is bought when its link is claimed (the person opens it on their phone and installs the QR), and links nobody claims withi
• verify_receipt ~194 tokens
  Verify an ed25519-signed receipt: the signature, and — unless you pass onChain:false — both txids against an Algorand indexer. Give it an orderId to check one of this service's own orders, or a receipt object to check ANY receipt in this format, including one issued by another server.
• voucher_batch ~133 tokens
  A paid voucher batch: every claim link, which have been claimed and delivered, the expiry, and any refund for unclaimed links. The batchId is the only handle on the links — keep it, and hand each person their own link privately (whoever opens a link first gets that eSIM).
