# Usage-Based Pricing

> Variable charges based on API consumption

Usage-based pricing in skills.video is credit-driven. Each generation task consumes credits, and Pro can extend usage through additional credit packs.

## Purpose

Use usage-based billing behavior when workload is variable and can exceed included monthly subscription credits.

## Usage units

| ------ | ---------------- | -------------------------------------------------------------- |
| Credit | Image generation | Credit usage depends on selected model and generation settings |
| Credit | Video generation | Credit usage depends on selected model and generation settings |
