Calculate the same GPT-5.5 official usage cost as sub2api, then apply it to a prepaid balance ledger. Returns debit, balance-after, low-balance policy, idempotency key, and exportable JSON for wallet or API-credit systems. Pay up to $0.10 per request with x402 USDC on Base or choose the fixed-price Solana USDC option when advertised.
