How payment works
Top up any whole-dollar amount you like — there is no fixed product catalog. Your balance is prepaid, never expires, and is spent only when API requests run.
- Pay by bank card or with cryptocurrency through a secure checkout provider.
- Every request is converted to official Anthropic API spend, then your active discount is applied.
- B2C accounts start 60% below official spend and progress up to 80% off as you top up more.
What you can do with the key
One key unlocks the full supported Claude line — Opus, Sonnet and Haiku — across Claude Code, Cursor, Cline, Continue, Zed and the official Anthropic SDKs. Nothing about the protocol changes; only the price does.
