AI image, video, and audio generation with persistent artifacts.Ship with one API.
Call leading generative models, track each task or wait for callbacks, and receive persistent artifact links without extra storage work.
Featured image, video, and audio models
Start with curated models for generation, editing, voice, and video workflows.
GPT Image 2
OpenAI image generation and editing with sharp text rendering.
Nano Banana 2
Google Gemini Flash image model, fast with strong character consistency.
Seedance 2.0
ByteDance cinematic video with native audio and multi-shot consistency.

One task API for every generation workflow
Submit a job, check status, receive a callback, and retrieve stored artifacts through the same simple lifecycle.
modelPass a model name to call any model through the same endpoint.
inputModel-specific parameters, validated per request.
storageSet persistent to get low-cost durable artifact links back.
callbackGet notified on completion instead of polling.

}'Ready for developers and AI agents
Integrate through API docs, MCP, Skills, and llms.txt so developers and agents can discover, call, and compose HiAPI.
API docs
Reference material for direct developer integration.
MCP
Agent-accessible tools for HiAPI workflows.
Skills
Reusable agent instructions for common workflows.
Use HiAPI in any agent
Paste the llms.txt prompt into your agent so it understands HiAPI models and APIs, then picks Skills, Remote MCP, or direct API as the setup path.
Read this HiAPI documentation index and answer my questions based on it: https://docs.hiapi.ai/llms.txt About HiAPI: a unified AI API gateway for image, video, and audio generation, with Agent Skills, Remote MCP tools, and an OpenAI-compatible API. My question: I want to generate an image or video with HiAPI. First decide whether Skills, Remote MCP, or the API fits best, ask me one key question if needed, then give the shortest setup steps.
Know the cost before you ship
Every model lists its price up front, so you can size usage before you integrate.
Transparent pricing
Review each model's price before integration.
Predictable cost
Estimate cost clearly before a production launch.
Cost-aware routing
Glance at '@beta', '@pro' suffix, knowing the cost level.
Volume discounts
Larger usage can get volume-based rates. Contact sales
Built for production generation workloads
Reliable access, persistent outputs, task tracking, and support for long-running image, video, and audio jobs.
Availability-first routing
Designed for stable access, not only the cheapest available route.
Persistent outputs
Generated artifacts stay reachable through returned links.
Optimized for Long-running jobs
Task tracking and callbacks fit image, video, and audio workloads.
24/7 support
Coverage for production integration and operation.
The real generation workflows's feedbacks
Representative scenarios from teams building AI video tools, creative automation, and agent workflows.
We test video models quickly, keep generated assets reachable, and skip building a storage path for every provider.
Persistent artifact links make it easy to pass outputs between campaign tools, review, and downstream automation.
A task API with callbacks gives agents a clean way to request, wait, retrieve, and reuse generated media.
Frequently Asked Questions
Quick answers on supported models, persistent artifacts, callbacks, and trying before you build.
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, so you skip polling.
Can I try models before integrating?
Yes. Use the Playground on each model page to explore parameters and example outputs before writing code.
