What is HiAPI?
HiAPI is an AI API gateway that generates images, video, audio, and text through a single unified, async task workflow with persistent artifact links.
One interface for multiple media types
HiAPI is built around a consistent task lifecycle for generative media. You submit a job for an image, video, or audio model (and text models via their native-style protocols), then track progress and retrieve outputs as durable links—so you don’t need to create custom storage per provider.
Async tasks: create, track, collect
HiAPI’s core workflow uses an async task API:
- Create a task with a POST to
/v1/tasksto receive ataskIdimmediately. - Track completion by polling
GET /v1/tasks/:id. - Or provide a callback URL so you’re notified when the job reaches its final state.
- Collect results through the task result, which returns output links (persistent artifacts).
Persistent artifact links for long-running jobs
Set storage to keep outputs long-term. Task results return durable links to your generated outputs, which makes it easier to pass media into downstream steps (review tools, campaign pipelines, or agent workflows) without building and maintaining provider-specific storage.
Availability-first routing and cost awareness
HiAPI uses a route field to select an available route such as default, beta, or ext, while keeping the same overall task workflow. Model pages list pricing details and parameters up front so you can size usage before shipping.
Agent-friendly integration paths
HiAPI is designed to be discoverable and callable by AI agents through standardized integration paths, including MCP, Agent Skills, and an llms.txt prompt that helps agents find models and use consistent workflows.
Try models before integrating
HiAPI includes a Playground on model pages to explore parameters and sample outputs before you integrate.
- Unified async tasks endpoint for image/video/audio generation
- Durable artifact links returned in task results
- Callback URLs to avoid polling
- Route selection via the
routefield - Agent-ready discovery via MCP, Skills, and
llms.txt

HiAPI offers a free API key. New user registration includes 200 Credits. Model pricing is usage-based and shown per model, with examples such as:
- Nano Banana: from $0.011 /image
- GPT Image 2.5: from $0.017 /image
- Qwen Audio 3.0 TTS: from $0.030 /1,000 characters
Video examples include:
- Kling 4.0: from $0.330 /second
- Wan 3.0 Video: from $0.040 /second
There is also a limited-time 20% off promotion for the newly launched GPT Image 2.6 Flare and Sunburst.
HiAPI FAQ
What does HiAPI unify under one API?
HiAPI unifies generation workflows under one interface for images, video, audio, and text. You submit tasks and use the same task-based lifecycle to create, track, and collect results as persistent artifact links.
How do I use HiAPI’s async task workflow?
Create a job by POSTing to /v1/tasks to get a taskId. Then either poll GET /v1/tasks/:id until completion or provide a callback.url so HiAPI notifies you when the task reaches its final state. Finally, retrieve results from the task response, which includes output links.
What are persistent artifact links in HiAPI?
Persistent artifact links are durable URLs returned with the completed task so you can access generated outputs later. To store outputs long-term, set the task storage to persistent so results stay reachable through returned links.
Can I get notified when a task is done without polling?
Yes. When you submit a task to HiAPI, you can include a callback configuration with a callback URL and set it to trigger on the final state, so you don’t need to repeatedly check status.
How do I route requests like default vs beta/ext?
Use the route field in the task input. For example, set route to default (or choose other available routes like beta or ext); leaving it out uses the default route while keeping the same task API flow.
Where can I see pricing before integrating?
Model pages show pricing and parameters up front before you integrate. This lets you review cost per unit (for example, per image, per second, or per token/character depending on the model) before sending generation jobs in production.
Is HiAPI free?
HiAPI provides a free API key, and new user registration includes 200 Credits. Model usage is billed based on the selected model’s usage-based pricing shown on the model pages.
