Calculation example
Lightweight chat app
Assume a single request has 1,000 input tokens and 500 output tokens. Cost calculation: (1,000 / 1,000,000) × $0.25 + (500 / 1,000,000) × $1.00 = $0.00025 + $0.0005 = $0.00075. That is, each request costs less than 0.08 cents.
Medium-scale data processing
Assume a single request with 10,000 input tokens and 2,000 output tokens. Cost: (10,000 / 1,000,000) × $0.25 + (2,000 / 1,000,000) × $1.00 = $0.0025 + $0.002 = $0.0045. Cost per 10,000 requests is about $45.
Long context reasoning
Assume a single request with 30,000 input tokens and 5,000 output tokens. Cost: (30,000 / 1,000,000) × $0.25 + (5,000 / 1,000,000) × $1.00 = $0.0075 + $0.005 = $0.0125. Cost per 10,000 requests is about $125.
Transparent and predictable billing
Wu Shencha API pricing is straightforward: $0.25 per million input tokens and $1.00 per million output tokens. This pricing structure allows you to calculate the cost of each call precisely. The prepaid model means your spending will not exceed your account balance, avoiding unexpected bills. All prepaid balance (from top ups) remains valid permanently, while only the free trial credit expires after 7 days.
Trial and top up bonuses
New users get $0.50 in free trial credit upon registration, no credit card required, valid for 7 days. Minimum top up is $10, supporting crypto (USDT, USDC). Top up $50 for +5% bonus, top up $100 for +10% bonus. Bonuses are credited immediately and can be used for API calls.
Flexible key management and request limits
Each account is limited to one API key, but you can regenerate it in the dashboard at any time. Once a new key is generated, the old key becomes invalid immediately, ensuring security. Each API key has a rate limit of 300 requests per minute and a request body size limit of 8 MB. These limits apply to all requests, including streaming and non-streaming outputs. For most applications, these limits are sufficient.
