What is Kie API?
Kie.ai is a unified API platform for accessing leading video, image, audio, and language models through one API and one prepaid credit wallet. Instead of a subscription, you top up a balance (roughly $0.005 per credit) and spend it per generation, with published prices typically 30-50% below calling providers directly, and some models discounted up to 80%.
Key features
- Unified REST API at api.kie.ai across video, image, audio, and text models
- Each model has a Playground to test before calling the API
- Transparent per-model pricing table (per image, per second, per video, or per million tokens)
- Prepaid credit balance shared across all models, with bonus credits on larger top-ups
- Typically 30-50% below official API pricing, some models up to 80% cheaper
How to get started
- Create an account at kie.ai
- Top up your credit wallet
- Browse kie.ai/market for the model you need
- Test it in the Playground
- Call the model's API endpoint with your key

Our take: The pitch is straightforwardly "same models, lower price" via negotiated bulk rates - worth comparing its dashboard pricing against CometAPI or Crun for your specific model mix before committing.
