Payment notes
Verified August 2026: USDC and USDT via Daimo Pay, with multi-chain deposits settling as USDC. Daimo Pay presents the available chains at checkout, so more may be supported than the three listed here. Pay-per-use rather than subscription, and the platform advertises very small minimum deposits — which is much of the point.
Refunds
Prepaid balances are generally non-refundable.
Stablecoin refunds are outbound payments a merchant chooses to send, not automatic reversals. There is no chargeback.
NanoGPT charges per prompt rather than per month, funded from a balance you top up in stablecoins.
Pay-per-use is the differentiator
Most AI products are monthly subscriptions, which is poor value for occasional use. Paying per request means someone who uses a model twice a week pays for two requests a week.
That billing model needs a funding mechanism that works for small amounts, which is exactly what a stablecoin balance on a cheap network provides. A two-dollar top-up is viable here and is not on most payment rails.
Small top-ups need cheap networks
The whole proposition falls apart if the network fee is comparable to the top-up. Use Base or Solana.
No subscription to cancel
There is nothing recurring. The balance sits until you use it.

An editor confirmed these payment options against the sources listed below.
NanoGPT's API documentation names its stablecoin rail directly: "Daimo Pay: USDC, USDT, ETH, SOL (multi-chain payments settling as USDC)." Deposits from multiple chains settle to a single USDC balance. The docs do not enumerate every supported chain, so the network list here is limited to those named.
