HiAPI

What is HiAPI

HiAPI is a unified AI API gateway for image, video, and audio generation. It provides a single endpoint and schema to call leading generative models, with persistent artifact storage, task tracking, and callbacks. It is designed for developers and AI agents, offering MCP, Skills, and llms.txt integration.

How to use HiAPI

1. Get an API key: Sign up at hiapi.ai to receive a free API key.
2. Choose a model: Browse the models page to select from curated image, video, and audio models (e.g., GPT Image 2, Seedance 2.0, FLUX 1.1 Pro).
3. Make a request: Use the unified /v1/tasks endpoint with your API key. Pass the model name, input parameters, storage preference, and optional callback URL.
4. Retrieve outputs: Generated artifacts are returned as persistent links. Use callbacks to be notified on completion instead of polling.

Example curl request:

curl https://api.hiapi.ai/v1/tasks \
  -H "Authorization: Bearer $HIAPI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-image-2/text-to-image",
    "input": {
      "prompt": "a glass speaker, studio light"
    },
    "storage": "persistent",
    "callback": {
      "url": "https://example.com/cb",
      "when": "final"
    }
  }'

Features of HiAPI

• Unified API: One endpoint and one schema for every image, video, and audio model.
• Persistent storage: Outputs come back as durable links. No storage to build or maintain.
• AI Agent friendly: MCP, Skills, and llms.txt ready to wire up.
• Production-grade: Availability-first routing, callbacks, and 24/7 support for real load.
• Transparent pricing: Every model lists its price up front.
• Cost-aware routing: Model suffixes like @beta and @pro indicate cost level.
• Volume discounts: Larger usage can get volume-based rates.
• Task tracking: Submit a job, check status, receive a callback, and retrieve stored artifacts through the same lifecycle.

Use Cases of HiAPI

• AI video SaaS teams: Test video models quickly, keep generated assets reachable, and skip building storage for every provider.
• Creative automation teams: Pass outputs between campaign tools, review, and downstream automation using persistent artifact links.
• Agent workflow teams: Use a task API with callbacks for agents to request, wait, retrieve, and reuse generated media.

Pricing

Every model lists its price up front. Model names may include @beta or @pro suffixes to indicate cost level. Volume discounts are available for larger usage; contact sales at hi@hiapi.ai.

FAQ

Which models does HiAPI support? HiAPI supports selected image and video generation models, with audio on the roadmap. Browse the full list on the models page.

How do persistent artifact links work? Set storage to persistent and generated outputs are stored for you and returned as durable links in the task result.

Can I use callbacks instead of polling? Yes. Provide a callback URL and HiAPI notifies you when the task reaches its final state.

Can I try models before integrating? Yes. Use the Playground on each model page to explore parameters and example outputs before writing code.
