Pay-per-use token rates
Our API charges strictly for consumed tokens, with input tokens at $0.15 per million and output tokens at $0.50 per million. This structure ensures you only pay for actual usage, avoiding hidden fees for idle time or reserved capacity. Errors and refusals do not incur charges, so you never pay for failed requests. The base URL for these endpoints is HTTPS://api.qwenapidocumentation.com/v1, and you can test the rates using standard OpenAI-compatible SDKs. This transparent model allows precise calculation of your unit economics before you send a single request.
Prepaid credit and no expiration
You fund your account with prepaid credit that never expires, giving you full control over your spending limits. There is no monthly subscription fee, and you are not locked into any recurring billing cycle. When your balance reaches zero, your API key simply stops working until you add more funds.
Crypto top-ups: USDT and USDC
We accept only USDT on the TRC20 network and USDC on the Base network for all top-ups. You can add any whole dollar amount between $20 and $500 per transaction. Your credit is applied immediately upon network confirmation, allowing you to start generating content without delay. This method keeps your billing private and avoids the friction of traditional payment gateways.
