Prepaid credit and expiry
Your prepaid balance covers all token usage for your API requests. You load credit once, and it applies to every call until depleted. Unlike monthly subscriptions, you never lose access to your key when the period ends; you simply top up when you need more capacity.
Credit never expires, so you can pause development for weeks without worrying about service interruption. This structure eliminates the risk of paying for unused capacity during off-peak periods. Errors and refusals consume no tokens, ensuring your balance reflects only successful work.
Crypto top-ups and bonuses
Top-ups are processed exclusively via cryptocurrency, specifically USDT on the TRC20 network or USDC on the Base network. You can deposit any whole amount between $20 and $500 per transaction. This method allows for instant credit activation without the delays associated with traditional banking or payment processors.
We offer bonus credit on larger top-ups to maximize your API budget. Deposits of $50 yield a 5% bonus, $100 grants a 10% bonus, and $200 provides a 15% bonus. These bonuses are added directly to your balance, effectively lowering your effective cost per token for high-volume users.
Rate limits and request costs
Your API key supports up to 300 requests per minute and 8 concurrent requests. Each request body is limited to 8 MB, which accommodates large context windows up to 100,000 tokens. These limits ensure stable performance for your applications while preventing resource exhaustion.
Costs are calculated per request based on the actual tokens consumed. Input tokens are billed at $0.15 per million, and output tokens at $0.50 per million. This granular billing ensures you pay precisely for the computational resources your model utilizes, with no hidden fees for streaming or function calling.
