Its supply is pooled unused ChatGPT and Claude subscription capacity contributed by other users, so it is subscription resale rather than official API access; onboarding is capacity-gated (a limited "Founding 200" cohort at launch) and purchases are non-refundable. Payment is crypto only per the operator: USDT on Tron, Ethereum, BSC, Solana, TON and other networks, plus USDC, BTC and LTC, with no card support. Kantro states it does not store prompts or use them for training.
