Cheap Claude access for coding. You pick a credit amount ($25, $50, $100, $200). After you redeem, you get an ek_cb_… API key and a base URL. Put those into Claude Code (or Cline, Continue, or Roo in VS Code). Every request is billed at Anthropic’s normal prices for Haiku, Sonnet, or Opus until the balance hits $0. Redeem another credit key on the same API key to add more. When the balance is empty, requests stop until you top up.
