Is there a subscription?
No. You prepay a balance in USD by card, and each request is deducted from it. Purchased credits last 12 months.
When do I move to Tier 2?

New requests are refused until you add credits.
Do I need to change my code?
Only the base URL and the key. The API is OpenAI-compatible, and the Anthropic Messages format works too.
