Pay for your AI API with crypto.
If a card or a foreign provider account is in your way, it does not have to be. Top up a prepaid balance with six assets, then call GPT, Claude, and Gemini through the OpenAI SDK you already use for a fraction of official pricing. A card works too.
Six assets, plus card.
Send any of these and your balance is credited once the network reaches the confirmations below. Stablecoins settle to the dollar, so the amount you send is the credit you receive. The number of confirmations is what keeps a deposit safe before it counts, and it differs by network.
| Asset | Network | Confirmations to credit |
|---|---|---|
| BTC | Bitcoin | 2 |
| LTC | Litecoin | 6 |
| ETH | Ethereum | 12 |
| SOL | Solana | 1 |
| USDT | Ethereum | 12 |
| USDC | Ethereum | 12 |
| USDC_SOL | Solana | 1 |
A top up in three steps.
Open Add funds, type the dollar value you want to credit, and choose Bitcoin, Ethereum, Solana, Litecoin, USDT, or USDC. A card is there too if you prefer.
We generate a one time address and the exact amount to send, with a countdown. Send it from your own wallet before the window closes.
The status moves from pending to confirming to credited as the network confirms. Your balance updates on its own. Nothing to claim, no invoice to chase.
Send the exact amount, and mind the window.
- Send the exact amount shown. The last few digits are a unique tag that ties your transfer to your account, so an exact send is matched and credited cleanly.
- Each payment has a countdown. If it expires before your transfer confirms, the payment simply shows expired and you start a new one. Nothing is lost on your side beyond the network fee you paid to send.
- Stablecoins like USDT and USDC settle to the dollar, so a 30 dollar send is a 30 dollar credit. For Bitcoin and the others, the dollar value is fixed at the amount shown when you create the payment.
- Faster networks confirm in seconds to a couple of minutes; Bitcoin can take longer because each confirmation is a new block. The status shows the live confirmation count while you wait.
Built for buyers a card cannot serve.
Plenty of developers cannot get a card that the big providers accept, or do not want to hand one over for usage based billing. Crypto removes that barrier. You fund a prepaid balance from your own wallet, in your own time, and start calling the frontier models immediately. There is no subscription and no minimum, so you can start with a few dollars and top up again whenever you like.
Prepaid, billed per token, every cost visible.
- No subscription and no minimum. You spend the balance down at the per token rate, and that is the only thing you are charged.
- Every API response and every chat reply returns the exact cost of that call in a chernion field, so spend is visible to the token.
- The same balance covers the API, the hosted chat, and the coding CLI.
- When the balance runs low, top up again with crypto or a card. Nothing else changes.
