  1. Choose a plan on the pricing page (token packs, API call plans, or subscriptions)
  2. Pay with cryptocurrency — Bitcoin, ETH, USDT, SOL and more accepted
  3. Receive your API key and proxy base URL within 24 hours (usually faster)
  4. Set ANTHROPIC_BASE_URL or base_url in your OpenAI client
