Free tier (100 scans/month) is self-serve — just generate a key in the dashboard, no payment needed. For Pro or Team, pay in USDC or USDT below — early access, so we activate by hand within hours (no card, no auto-renew).
Enterprise / custom volume → contact sales. Prices are monthly; while billing is manual there is nothing on file to auto-renew — your tier stays active for the month you paid, and you simply stop or renew. Self-serve metered checkout comes later.
