Books that can’t disagree
A gateway in front of the model, a contract behind it, kept in lockstep.
Self-custody credits
Hold qToken in your own wallet. Deposit only what you plan to spend, and withdraw whatever you haven't burned.
Real model calls
Your deposit escrows into the gateway, which issues API keys and meters every gpt-4o-mini call against your balance.
Settled on-chain
Spent quota burns back to the contract. The books reconcile, and credit you have already used can never be withdrawn.
