How to pay for ChatGPT, Claude and Gemini with crypto — per message, no subscription (2026)

Frontier models — GPT-5, Claude, Gemini — can be used by the message for GRAM or USDT, with no monthly subscription and no bank card. You pay for specific requests from your wallet; no auto-charges, no card on file, no region locks on payment. Below: who this beats a subscription for, and how to start.

Subscription or per-message — which to pick

Monthly plans (ChatGPT Plus, Claude Pro, etc.) pay off if you use the model every day. But if you need AI in bursts — a couple of tasks a week, a one-off generation, access from a region where you can't add a card — the subscription sits idle. Pay-per-use covers exactly that: you only pay for what you actually used.

  • No monthly subscription, no auto-renewal.
  • No bank card — pay in GRAM/USDT from your wallet.
  • Several models from one place, no separate account per model.

What you need first

  1. A wallet with GRAM/USDT — non-custodial (Which TON wallet to choose).
  2. A balance — top up with a card via How to buy GRAM.

Models available per-message on Catallaxy

Need full Claude access for a month with no card? There's a separate product — Claude Pro gift code.

How it works

  1. Open the page for the model you want (links above).
  2. The per-request price is shown on the card in GRAM/USDT.
  3. Confirm the payment in your wallet — you get the model's response. No card needed.

Pitfalls

  • Do the math. If you genuinely run many tasks every day, a subscription may be cheaper; pay-per-use wins on irregular usage.
  • GRAM for small payments (minimal fee), USDT if you want to lock the dollar cost (GRAM vs USDT).

FAQ

Can I use GPT/Claude without a subscription? Yes — pay per request, no monthly plan.

Do I need a card? No, just GRAM/USDT from your wallet.

Are these the official models? Yes, access to current frontier models; you only pay for use.
