lookup_phone | 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 the human and have them confirm it before buying, and use `other_brands` to correct it — a voucher bo params: phone* |
list_offers | 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. params: type*, country, brand, limit, offset |
quote | 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. params: type*, offerId*, phone, amount, iccid, fields, sender, payer, ref |
create_pay_link | 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 the page. You never hold a key. A top-up link can be paid by anyone — send it to family as 'top up my params: type*, offerId*, phone, amount, note, ref, max_uses, ttl_hours |
buy | 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 human confirmation of the quote. Works the same for a quote from quote_vouchers; the paid response is params: quoteId* |
quote_vouchers | 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 within 30 days are refunded to the paying wallet. Free. Pay the returned quoteId with `buy`, or send the params: offerId*, count*, note, payer |
voucher_batch | 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). params: batchId* |
order_status | Check an order. Poll every ~3 s until `terminal` is true: delivered (confirmation + signed receipt), refunded (refund txid + signed receipt) or refund_failed. params: orderId* |
verify_receipt | 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. params: orderId, receipt, onChain |
fx | Indicative USDC → local-currency rate at our sale price, with an estimate for an amount. The quote is the binding price. params: to*, amount, type |
ledger | Public delivery ledger: totals, delivered-or-refunded %, volume, countries, recent orders. params: none |
