KIE

KIE is a unified AI API gateway for teams that use multiple model providers at once. It gives one place to access video, image, audio, and LLM endpoints through consistent request patterns. KIE keeps the integration surface simple while still letting you pick models with different strengths and price points across media formats.

The platform positions cost as a practical advantage by offering many models through one credit system instead of forcing separate vendor billing flows. New users can start with 80 free credits for testing, then buy top ups as usage grows. Task failures are not charged. That billing behavior matters when you are evaluating outputs in production tests or batch jobs.

KIE also puts support features directly in the API journey. You can route jobs by model id, return to webhooks or polling, and review detailed logs for status, timing, and error context. The docs and playground cover setup with practical endpoints, and the dashboard keeps model usage and balance visible in one place.

One API for multiple families: route across image, video, audio, and LLM models without rebuilding your integration layer for each provider.
Free test credits: new users receive a starter credit amount before any card payment.
Shared wallet: credits stay in one balance for all supported model categories.
Webhook and polling support: choose callback or status polling to fit your backend architecture.
Model comparison: preview leading models and pricing differences before deciding where to run workloads.
Failed task policy: no charge for failed generation tasks.
Central monitoring: logs and status visibility help with debugging and operational follow through.
Developer docs and playground: test prompts and settings in an official environment before shipping.
