Credits System

Wizzx uses a credit-based pricing system:
  • 1000 credits = $1 USD
  • An accepted submission reserves credits. Successful tasks confirm the charge; failed tasks are refunded; REVIEW_REQUIRED tasks remain reserved for reconciliation.
GET /pricing is the source of truth for the rates of models documented here. Compatibility-only backend keys may be intentionally omitted from the public catalog below.

​
Image Generation

Seedream is billed per generated image: batch_size is pre-authorized and the difference is refunded after settlement. Input reference images are not billed.

​
Video Generation

Video billing depends on the model. Veo 3.1 is fixed per generated video; other listed video models may bill per second or per request.
Current gateway limitation: Seedance Pro Fast reaches its 480p default only when resolution is omitted; Seedance 1.5 Pro currently accepts explicit 720p only. The 480p catalog tiers remain listed for pricing transparency while the backend binding is being corrected.

​
Veo

All Veo rows support 4, 6, or 8 seconds at the same fixed price. The values apply Wizzx’s cost-plus customer pricing to Kie’s 2026-08-18 USD costs at 1000 credits = $1; check GET /pricing before submission.

Cost Calculator

To calculate your cost:
  1. Find the credits for your model and parameters above
  2. Multiply by usage (e.g., seconds for video)
  3. Divide by 1000 to get USD cost
Example: Generate a 10-second 720p video with Seedance Pro Fast
  • Credits: 20 credits/s × 10s = 200 credits
  • Cost: 200 ÷ 1000 = $0.20
