Use cases
For API users who prefer no fixed monthly fee and accept prepaid balance, card fees and model-specific privacy. Check the selected model policy before sending sensitive code.
Keep in mind
Card fee: docs state 4.4% + $0.30 per transaction; the $20 marketing example shows $1.23, pending reconciliation. Auto-reload cash charges may exceed the monthly usage limit. Free access may expire or allow training. OpenAI/Anthropic retain requests for 30 days; NVIDIA trials log data. Check model-specific privacy.

- Source notes and limits
- Zen is a pay-as-you-go API product; Go and Go Plus remain subscriptions. The initial $20 purchase adds balance, with a separate card processing fee. Model prices, context tiers and temporary free policies use verified official channel records.
