Our AI agent bought an eSIM for its owner, then got the money back. Every step is on chain.

Описание и применение

AI‑агент ARGUS купил eSIM за 0,31 USDC, получил QR‑код и код активации, а затем вернул деньги, сохранив секретный код вне модели и не тратя ETH.

Задача

An AI agent must safely purchase and refund an eSIM while keeping sensitive data out of the language model and avoiding unintended payments.

Результат

ARGUS successfully bought a Turkey eSIM for 0.31 USDC, received the QR and activation code, and later refunded the exact amount, all while keeping the activation code out of the language model and never spending any ETH.

Рабочий процесс

• Owner sends "buy me the cheapest eSIM for Turkey" to ARGUS in Telegram.
• ARGUS asks for clarification and receives owner’s confirmation to buy. ARGUS queries the eSIM marketplace for offers. ARGUS selects a seller, checks price cap (≤1 USDC), and obtains seller’s payment terms. ARGUS signs an EIP‑3009 transfer authorization for 0.31 USDC and sends it via x402. Seller issues eSIM, returns QR and activation code to ARGUS’s Telegram channel. Owner requests refund after 34 minutes. ARGUS verifies eSIM not installed (0 bytes used), signs refund transfer, and sends it back via x402. All transactions are recorded on Base and visible via tx links.

Доказательства

ARGUS paid over x402: the seller answered the order with 402 Payment Required and its terms, and ARGUS signed one EIP‑3009 transfer authorization for exactly that amount.

Источник

The activation code is the traveller's secret: whoever has it can install the eSIM. So it goes from the seller to the owner's chat through the tool's code, around the language model.
