Hiapi
Call leading generative models for image, video, and audio creation through a single task-based API that stores outputs for you
Last verified:
What is Hiapi?
HiAPI is a unified AI API platform for image, video, and audio generation. It is designed to let developers call many leading generative models through one API key and one task-based workflow. The site emphasizes persistent artifact delivery, so outputs are returned as durable links instead of requiring you to build your own storage layer.
The core workflow is simple: submit a task, get back a taskId, then poll for results or receive a callback when the job finishes. HiAPI supports image, video, and audio generation through a single /v1/tasks endpoint, with model-specific inputs validated per request. It also offers an OpenAI-compatible API, which makes migration easier for teams already using similar request patterns.
HiAPI highlights features for production use, including availability-first routing, callbacks, HTTPS security, and 24/7 support. The platform also provides global CDN coverage and scoped API keys that can be revoked. Its docs stress that the same API shape works across many workflows, including text-to-image, image-to-image, text-to-video, and image-to-video.
The product is also positioned as agent-friendly. It supports Agent Skills, Remote MCP tools, and llms.txt so coding agents and other assistants can discover and use the platform more easily. In practice, HiAPI is aimed at developers, AI app builders, and teams shipping creative automation, agent workflows, or production media-generation features.
Hiapi pricing
Pricing model: Freemium
HiAPI offers a free starting credit for new users: the docs say new accounts get $1 free credit. After that, the platform uses pay-as-you-go billing, with every model showing its price up front before integration. The site also mentions volume discounts for larger usage, which requires contacting sales. Pricing examples on the site include flat per-task and model-based rates in the blog content, but the main pricing message is that costs are transparent, model-specific, and billed as usage rather than a monthly bundle.

Frequently asked questions about Hiapi
What does HiAPI do?
HiAPI is a unified API gateway for generating images, videos, and audio through one task-based interface. You send a request to the platform, it creates a task, and then returns the finished artifact as a durable link or via callback when the job is done.
How does the HiAPI workflow work?
The standard flow is: sign up, create an API key, add funds, submit a task to POST /v1/tasks, then check the result with the returned taskId or receive a callback. The docs say tasks move through statuses such as queued, handling, archiving, success, and fail.
Does HiAPI support callbacks?
Yes. You can provide a callback URL so HiAPI notifies your app when the task reaches its final state. This is meant to reduce or eliminate polling in production workflows.
What kinds of models are available?
HiAPI highlights selected image, video, and audio generation models. The homepage and docs mention models such as GPT Image 2, Nano Banana 2, Seedance 2.0, HappyHorse 1.1, FLUX 1.1 Pro, and Qwen Image 2.0.
How are outputs delivered?
Outputs are returned as persistent artifact links when storage is set to persistent. The platform says these links are durable, so you do not need to build your own storage system to keep generated files available.
Do I need a dedicated SDK?
No. The docs say you can use any HTTP client, including cURL, Python, or Node.js. That means you can integrate with HiAPI from most environments without waiting for a language-specific SDK.
Is HiAPI suitable for agents?
Yes. The site explicitly positions it as AI-agent friendly through Agent Skills, Remote MCP, and llms.txt. It also says these options help coding agents and other assistants discover and use the platform more easily.
How much free credit do new users get?
The docs say new users get $1 free credit to start. The site also notes that new accounts usually receive enough trial balance to verify the flow before they add more funds.
How is HiAPI priced?
HiAPI uses pay-as-you-go billing after the initial free credit. The site says each model lists its price up front, so you can estimate usage before you integrate, and it also mentions volume discounts for larger usage.
What makes HiAPI production-ready?
HiAPI emphasizes availability-first routing, persistent outputs, task tracking, HTTPS encryption, and 24/7 support. The docs also note that API keys are scoped and revocable, which is useful for operational control and security.
