lookup_phoneIdentify 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 dete
list_offersBrowse 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.
quoteDemo only: payments are switched off, so this answers with an error and nothing can be bought. 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.
create_pay_linkDemo only: payments are switched off, so this answers with an error and nothing can be bought. 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, se
buyDemo only: payments are switched off, so this answers with an error and nothing can be bought. 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 yo
quote_vouchersDemo only: payments are switched off, so this answers with an error and nothing can be bought. 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 boug
voucher_batchA 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).
order_statusCheck an order. Poll every ~3 s until `terminal` is true: delivered (confirmation + signed receipt), refunded (refund txid + signed receipt) or refund_failed.
verify_receiptVerify 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 se
fxIndicative USDC → local-currency rate at our sale price, with an estimate for an amount. The quote is the binding price.
ledgerPublic delivery ledger: totals, delivered-or-refunded %, volume, countries, recent orders.

Demo only: payments are switched off and nothing can be bought. This is a technology demonstration, not a commercial service.
Your AI agent can buy real things — and send money. In the pilot today: travel eSIMs and mobile airtime/data top-ups. Prepaid bills and international payments (bank / mobile money / UPI payouts via a licensed partner) are built and supplier-gated. Everything is paid per order in USDC on Algorand via x402. No account, no API key, no card. Money settles on-chain first, goods ship second, failures refund on-chain automatically, and every terminal order carries an ed25519-signed receipt anyone can verify.
Built for the Global x402 Challenge (Algorand Foundation × GoPlausible). Pilot: https://iomarkets.app · agent docs: /agent.md · ledger: /v1/ledger · receipt spec: docs/RECEIPTS.md

GET /.well-known/agent-card.json · GET /.well-known/agent.json | free | A2A agent card — what registries and agent routers read: the live skill list (rendered from what the suppliers can actually fill), the provider, and x402 declared as a required capability with the paid route named. Claims no transport and no url: this server does not speak A2A JSON-RPC, and neither HTTP+JSON nor a made-up MCP is an honest value for that field, so the card is discovery metadata and documentationUrl sends a caller to /agent.md for the interface that exists (src/agent-card.ts) | |||

Mock supplier rules for demos: a phone ending `0000` fails (→ refund path), `1111` is delivered after polling.
