How prepaid credit keeps your spending predictable
You fund your account with cryptocurrency and spend exactly what you consume. There are no monthly subscriptions or hidden fees. Errors and refusals cost nothing. Your prepaid balance acts as a strict budget cap for your API usage.
We charge $0.15 per million input tokens and $0.50 per million output tokens. You can top up any whole amount between $20 and $500. The credit never expires. This model works well for developers who want to track every dollar spent on inference.
Start testing with our free trial credit
Every new account receives $0.50 of trial credit to verify the API works for your stack. The trial credit is valid for seven days from the moment you sign up.
This allows you to test streaming, function calling, and JSON mode without risking your main balance. Use the trial to confirm the base URL and model ID match your expectations before buying crypto credit.
Refunds and credit expiration policy
Your prepaid credit never expires. You can add funds whenever you need more capacity. We do not refund the initial credit purchase. If you make a mistake like a double charge, you can fix it through the Support page.
Errors during processing do not consume your tokens. If the API returns an error, you are not charged. This keeps your prepaid balance accurate for your actual successful requests.
