One service, one allowance, one link.
A pass is a link you paste into your chatbot. It spends only at the service you choose, and only up to what you load. Your agent never gets your card or your wallet. If you had added the service itself, remove that entry: the pass takes its place.
The link is the key: we do not store it. Whoever holds it can spend the pass at that service, and nowhere else. If you lose it, come back to the pass page, name the service, connect the same wallet and choose Find my passes.
Funding is free. You pay the service’s own prices. You need a wallet that runs in your browser, such as the MetaMask or Coinbase Wallet extension, holding USDC on Base. A service can take at least a set amount; the pass page names it before you sign.
The balance stays on the pass until you send it home. It goes only to the wallet that funded it. Sending it home is free once ZEAM’s fee on what the pass spent (9.99% of it at a service running ZEAM :: Bridge; all of it where ZEAM is the seller) covers the gas of your deposit, your refund and any calls not yet settled, and of any further deposit and any earlier refund ZEAM paid for on your pass, plus 15%; before that the refund’s network fee plus 15% comes out of what is returned, and you see the amount before you sign.
