Billing is per second with no minimums; payment is crypto only (USDT, BTC, XMR, ETH, SOL, LTC, TRX) with no KYC. Instances run in Tier-III datacenters across 32 regions with a 99.9% uptime SLA and deploy in about 30 seconds from the web console (cloud.powergpu.ai) or the REST API.\n\nPricing and inventory endpoints are public and need no key, so any client can read the whole price sheet before creating an account. Instance lifecycle and balance endpoints authenticate with a Bearer key created in the console.\n\nPrices are USD per GPU-hour and follow one published rule: the public GPU marketplace median for the model x 0.70, rounded down, re-checked weekly.
