KIE
A unified API for chat, image, video, and music models, backed by one shared credit wallet.
About KIE
KIE gives developers one API account for chat, image, video, and music models. Its model market and playground expose parameters and output formats for testing before integration, while a shared credit wallet covers supported models. Media generation uses an asynchronous workflow: a successful request creates a task ID, and the finished output is delivered by callback or retrieved through polling. API keys support hourly, daily, and total usage caps as well as IP whitelisting. Task logs record creation time, model, inputs, status, credit use, results, and errors. Generated media remains available for 14 days; text-based activity logs remain for two months. Usage pricing varies by model and output type. KIE offers a free API key and does not charge for failed generation tasks. The service best fits backend products that can manage task state and want to consolidate multiple AI media categories behind one integration.
Best for
Best use cases
A prototype compares model parameters and output formats in the playground before API implementation begins.
A backend creates a media task and retrieves the finished result through a callback or task-ID polling.
A production service restricts an API key with usage caps and an IP whitelist while tracking task logs.
Compare before choosing
The unified endpoint reduces separate integrations when a product needs multiple media and language model categories.
Usage rates depend on the selected model and output, so costs require workload-specific comparison.
Asynchronous generation suits queued backend workflows but adds task-state handling compared with synchronous APIs.
Features
Unified multimodal API
Connect chat, image, video, and music models through one API account and a shared credit wallet.
Prototype in the playground
Test model behavior, parameters, and output formats in the web playground before implementing API calls.
Run asynchronous generation
Create media-generation tasks, then receive results through a callback URL or poll by task ID.
Pros
- One API account covers several chat, image, video, and music model categories.
- A shared credit wallet simplifies usage management across supported models and output types.
- Usage caps, IP whitelisting, task logs, and playground testing support controlled backend integration.
Cons
- Asynchronous generation requires callback or polling logic plus task-state handling in the backend.
- Generated media is deleted after 14 days, so long-term workflows need their own result storage.
- Model-dependent rates make total cost less predictable until the expected workload mix is known.
Pricing Plans
Usage-based credits
- One shared credit wallet across supported models
