HiAPI

HiAPI is the ultimate developer-first AI API platform that flips the script on generative AI integration. Forget juggling a dozen different API keys, dealing with fragmented billing systems, and wrestling with incompatible request formats. HiAPI hands you a single, unified endpoint that unlocks a powerhouse of leading image, video, audio, and text generation models. You get one API key to rule them all, with OpenAI-compatible requests that make migration a breeze. The platform is built for devs who want to ship fast and scale hard, offering pay-as-you-go pricing, unified billing, and persistent artifact storage that means you never have to build or maintain your own storage infrastructure. Whether you are generating cinematic videos with Seedance 2.0, creating sharp text-rendered images with GPT Image 2, or composing complete songs with MiniMax Music 2.6, HiAPI handles the heavy lifting. It is designed for production-grade workloads with availability-first routing, callback notifications, and 24/7 support. Plus, it is AI agent friendly out of the box, supporting MCP, Skills, and llms.txt for seamless integration with Claude, Cursor, Codex, and other agents. From indie hackers to enterprise teams, HiAPI is the gateway to shipping generative AI without the headache.

Unified API with One Endpoint

Stop managing a chaotic mess of different APIs for every model. HiAPI gives you a single endpoint and a consistent schema for every image, video, and audio model in its roster. You just pass the model name and your input parameters, and the platform handles the rest. This means your codebase stays clean, your integration time drops to minutes, and you can swap models on the fly without rewriting a single line of logic. It is the ultimate flex for developers who value speed and simplicity.

Persistent Artifact Storage

Say goodbye to the nightmare of building and maintaining your own storage for generated outputs. Every image, video, and audio file comes back as a durable, low-cost persistent link. You set the storage parameter to persistent, and HiAPI automatically hosts your artifacts. No more worrying about expiration dates, server costs, or file management. You get a reliable URL that works forever, letting you focus on building your product instead of babysitting infrastructure.

AI Agent Ready Architecture

HiAPI is not just for human developers; it is built for the age of AI agents. The platform ships with MCP tools, reusable Skills, and a comprehensive llms.txt file that agents like Claude, Cursor, and Codex can instantly understand and use. You can paste a single prompt into your agent, and it will know exactly how to call HiAPI models, pick the right integration path, and start generating. This makes HiAPI the perfect backbone for autonomous workflows and agent-driven content pipelines.

Production-Grade Reliability with Callbacks

When you are shipping at scale, polling for task completion is a waste of time and resources. HiAPI offers a callback system that notifies your application as soon as a generation task is complete. You set the callback URL and when to trigger it, and the platform handles the rest. Combined with availability-first routing that automatically directs requests to the healthiest endpoints, you get a rock-solid foundation for high-traffic applications that cannot afford downtime or latency.

Rapid Prototyping for AI-Powered Apps

Indie developers and startup teams can use HiAPI to prototype generative AI features in hours instead of weeks. With one API key and a unified endpoint, you can quickly test different models for image generation, video creation, or music composition. The pay-as-you-go pricing means you only pay for what you use, and the persistent storage eliminates the need to set up separate file hosting. This lets you iterate fast, validate ideas, and launch MVPs without burning through your budget.

Building AI Agents for Content Creation

AI agents need reliable, easy-to-integrate tools to generate content autonomously. HiAPI is tailor-made for this, offering MCP tools and Skills that agents can discover and use without manual configuration. An agent can generate a series of images for a blog post, compose background music for a video, and then create the video itself, all through a single API. The callback system ensures the agent knows when each task is done, enabling complex multi-step workflows that run on autopilot.

Enterprise Content Pipelines at Scale

Large organizations that need to generate thousands of images, videos, or audio files daily can rely on HiAPI for production-grade performance. The availability-first routing ensures that requests are always sent to the most responsive servers, while the unified billing and transparent pricing make cost management predictable. The persistent artifact links integrate seamlessly with existing content management systems, and the 24/7 support means any issues are resolved fast. This is the infrastructure for serious content operations.

Creative Experimentation with Multiple Models

Artists, designers, and content creators can use HiAPI to experiment with different AI models without managing multiple subscriptions. You can generate an image with Seedream 5.0 Pro for its sharp text rendering, edit it with GPT Image 2, and then turn a description into a full song with MiniMax Music 2.6, all from the same platform. The unified API makes it trivial to compare outputs from different models and choose the best one for your project, unlocking creative possibilities that were previously locked behind fragmented tools.

How does the unified API work with different models?

You simply pass the model name in your request to the single POST /v1/tasks endpoint. Each model has its own specific parameters that you include in the input field, but the overall request structure and authentication remain the same. This means you can switch from GPT Image 2 to Seedream 5.0 Pro by just changing the model name, without touching any other part of your code.

What is persistent artifact storage and how do I use it?

Persistent artifact storage means that every output file from your generation tasks comes back as a durable URL that does not expire. To use it, simply set the storage parameter to persistent in your API request. HiAPI then hosts the file on its infrastructure, and you receive a link that you can use indefinitely. This eliminates the need to set up your own storage buckets or manage file expiration.

Can I use HiAPI with AI agents like Claude or Cursor?

Absolutely. HiAPI is built to be AI agent friendly. It provides MCP tools, reusable Skills, and an llms.txt file that agents can read and understand. You can paste the llms.txt prompt into your agent, and it will know exactly how to call HiAPI models, pick the right integration path (Skills, Remote MCP, or direct API), and start generating content. This makes it a perfect fit for autonomous workflows.

How does the callback system work for task completion?

When you submit a generation task, you can include a callback object with a URL and a when parameter set to final. HiAPI will send a POST request to that URL with the task results as soon as the generation is complete. This eliminates the need for polling and allows your application to react immediately to finished tasks, making it ideal for real-time applications and complex multi-step workflows.

HiAPI operates on a transparent, pay-as-you-go pricing model. Every model lists its price per request or per unit of output directly on the model details page, so you know exactly what you will be charged before you integrate. There are no hidden fees, no monthly commitments, and no tiered plans that lock you into a specific usage level. You get up to 1 dollar in free credits when you sign up, allowing you to test the platform without any upfront cost. Billing is unified across all models, meaning you get a single invoice for all your usage, whether you generate images, videos, or audio. This predictable cost structure lets you estimate your expenses clearly before a production launch and scale your usage without worrying about unexpected bills.
