GUIDE

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.

WALKTHROUGH

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.

  1. 01
    Create an account and sign in

    Sign in with an email. Your account holds one prepaid balance that every part of Chernion draws from.

  2. 02
    Open 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.

  3. 03
    Send 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.

  4. 04
    Get credited on confirmation

    Once the network confirms, your balance updates automatically. No invoice to chase, no manual step.

  5. 05
    Start 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.

IF SOMETHING IS OFF

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.
