IoMarkets Topup (demo) is a remote MCP server that gives an AI agent 8 tools, among them buy, fx, ledger. It answers at https://iomarkets.app/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 11 of 11 times since 4 September 2026; the last check, on 7 November 2026, succeeded.
Travel eSIMs and mobile top-ups paid in USDC via x402. A technology demonstration, limited pilot.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 t Inputs: quoteId |
fx | Indicative USDC → local-currency rate at our sale price, with an estimate for an amount. The quote is the binding price. Inputs: to, amount, type |
ledger | Public delivery ledger: totals, delivered-or-refunded %, volume, countries, recent orders. |
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. Inputs: type, country, brand, limit, offset |
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 Inputs: phone |
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. Inputs: orderId |
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. Inputs: type, offerId, phone, amount, iccid, fields |
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 fo Inputs: orderId, receipt, onChain |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://iomarkets.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: app.iomarkets. Endpoint host: iomarkets.app. ARD identifier: urn:air:app.iomarkets:mcp:topup.
First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
