Is gift-by-crypto safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• quote_amazon_jp_egift unknown never probed

  Get a quote for a MOCK Amazon.co.jp eGift card (TESTNET, Base Sepolia test USDC) and the EIP-712 typed data (USDC TransferWithAuthorization) the payer's wallet must sign to pay it. Read-only: nothing is signed or paid. Refused if the price is above max_usdc. Valid for about 5 minutes; after the user approves, sign sign.typedData with the wallet and call buy_amazon_jp_egift with the buy fields.

• buy_amazon_jp_egift unknown never probed

  Buy the quoted MOCK Amazon.co.jp eGift card with the payer's signature over the quote's typed data. Moves test USDC from the payer to the service once. Call it once per quote, only after the user approved the price; never retry automatically. Returns the masked MOCK code, the settlement tx and a signed receipt (check it at /verify).
