Pay for an AI API with crypto.
If a card is in your way, crypto is the way in. Here is the whole flow, from signing in to your first billed call, paying with one of six assets and getting credited automatically once the transaction confirms on chain.
Five steps to your first billed call.
The balance is prepaid, so there is no subscription and no minimum. You can top up again any time with crypto or a card.
- 01Create an account and sign in
Sign in with an email. Your account holds one prepaid balance that every part of Chernion draws from.
- 02Open Add funds and choose crypto
Enter the amount you want to credit. Pick Bitcoin, Ethereum, Solana, Litecoin, USDT, or USDC. A card is there too if you prefer.
- 03Send the exact amount
We show a payment address, the exact amount, and a countdown. Send it from your wallet. Stablecoins settle to the dollar, so the amount you send is the credit you receive.
- 04Get credited on confirmation
Once the network confirms, your balance updates automatically. No invoice to chase, no manual step.
- 05Start calling the models
Use your key with the OpenAI or Anthropic SDK and call GPT, Claude, and Gemini. Each response returns its exact cost, so you watch the balance draw down to the token.
The two things people ask about.
- Send the exact amount shown. The trailing digits are a unique tag that matches the transfer to your account, so an exact send is credited cleanly.
- Each payment has a countdown. If your transfer does not confirm before it expires, the payment shows expired and you start a new one. Stablecoins settle to the dollar, so a 30 dollar send is a 30 dollar credit.
