HiAPI

HiAPI is the ultimate developer-first AI API platform that supercharges your creative workflows by providing unified access to the world's leading image, video, and audio generation models! With just one API key, you can instantly call top-tier models like GPT Image 2, Seedream 5.0 Pro, FLUX 1.1 Pro, Seedance 2.0, MiniMax Music 2.6, and many more. This platform is built for developers, AI agents, and teams who need to ship generative AI features fast without getting bogged down by managing multiple provider accounts, separate billing systems, or complex storage infrastructure. HiAPI streamlines everything into a single, elegant developer experience. You get OpenAI-compatible requests for easy migration, unified billing that consolidates all your model usage into one simple invoice, and pay-as-you-go pricing that scales with your needs. The real magic is in its persistent artifact storage system every generation returns a durable link so you never have to build or maintain your own file storage. Plus, with features like callbacks, idempotency keys, and availability-first routing, HiAPI is production-grade and ready for real-world load. Whether you are building a content generation app, powering an AI agent, or automating marketing workflows, HiAPI gives you the tools, models, and reliability you need to innovate without limits. Get started today with free credits and experience the power of unified AI generation!

Unified API for Every Model

Stop juggling multiple API endpoints and authentication schemes. HiAPI gives you one single endpoint and one consistent schema for every image, video, and audio model in our catalog. Simply pass the base model name, your input parameters, and optional settings like route or callback, and HiAPI handles the rest. This unified approach dramatically reduces integration time, simplifies your codebase, and makes it trivial to swap models or test different providers without rewriting any logic. It is developer heaven!

Persistent Artifact Storage Built In

Say goodbye to building and maintaining your own file storage infrastructure! Every output generated through HiAPI comes back as a durable, persistent link. When you set the storage parameter to persistent, your generated images, videos, and audio files are stored securely and accessible forever via that link. This feature saves you countless hours of development time, eliminates storage costs, and ensures your users always have access to their generated content. It is a game-changer for production applications.

AI Agent Ready with MCP, Skills, and llms.txt

HiAPI is designed from the ground up to work seamlessly with modern AI agents like Claude, Cursor, and Codex. We provide Remote MCP tools for agent-accessible workflows, reusable Skills that contain pre-built instructions for common generation tasks, and a comprehensive llms.txt file that agents can read to understand the entire API. Just paste the llms.txt prompt into your agent, and it instantly knows how to call models, handle tasks, and retrieve artifacts. This makes HiAPI the perfect backend for autonomous AI workflows.

Production-Grade Reliability and Callbacks

When you are shipping to real users, reliability is non-negotiable. HiAPI delivers with availability-first routing that automatically directs your requests to healthy model endpoints, ensuring high uptime and fast responses. We also support webhook callbacks so you can get notified when a generation task completes instead of polling the API. Combined with idempotency keys that prevent duplicate task creation on retries, HiAPI gives you the robust, enterprise-ready infrastructure you need to scale with confidence. Plus, our 24/7 support team is always there when you need us.

Rapid Content Creation for Marketing Teams

Marketing teams can leverage HiAPI to generate stunning images, promotional videos, and background music in seconds. With models like GPT Image 2 for sharp text rendering and Seedream 5.0 Pro for high-fidelity image generation, you can create social media assets, blog visuals, and ad creatives at scale. The persistent artifact links mean you can instantly share outputs with your team or embed them in campaigns without any storage hassle. It is the fastest way to turn creative ideas into publishable content!

Powering AI Agent Workflows and Automation

Developers building autonomous AI agents can integrate HiAPI as the creative engine for their bots. Whether your agent needs to generate an illustration for a report, compose a song for a playlist, or create a video summary of data, HiAPI's MCP tools and Skills make it trivial. Agents can discover the API, call models, and retrieve artifacts all through natural language instructions. This use case is perfect for personal assistants, research tools, and automated content pipelines that need to operate without human intervention.

Building Generative Features for SaaS Applications

SaaS platforms can embed HiAPI to offer generative AI features directly to their users. Imagine a design tool that lets users generate custom images with FLUX 1.1 Pro, or a video editing app that adds cinematic clips from Seedance 2.0. With one API key and unified billing, you avoid the complexity of managing multiple provider accounts for each feature. The callback system ensures your app can asynchronously process generation tasks and update users in real-time, creating a smooth and professional experience.

Music and Audio Production for Creators

Musicians, podcasters, and content creators can use HiAPI to generate original music and audio with MiniMax Music 2.6. This model turns prompts and lyrics into complete songs, complete with an instrumental mode. Whether you need a background track for a video, a jingle for a brand, or a full song for a project, HiAPI makes it incredibly easy. The persistent storage means you get a durable link to your audio file that you can share, download, or embed anywhere. It is a powerful tool for any audio creator!

HiAPI operates on a straightforward pay-as-you-go pricing model with transparent costs listed for each model. You can sign up and receive up to $1 in free credits to start testing immediately. Every model page on our website displays its exact price per generation, so you know the cost upfront before you integrate. There are no monthly commitments or hidden fees you only pay for the generations you actually use. This predictable pricing makes it easy to budget for your projects and scale your usage confidently from prototype to production.

What is HiAPI and how does it work?

HiAPI is a unified AI API gateway that gives developers access to multiple leading image, video, and audio generation models through a single API key. You make requests to our single endpoint, specifying the model and input parameters. HiAPI then routes your request to the appropriate provider, processes the generation, and returns a persistent artifact link. You only pay for what you use with our pay-as-you-go pricing. It is designed to simplify your workflow and eliminate the need to manage multiple API integrations.

Do I need my own storage to save generated content?

No, you do not! One of HiAPI's standout features is built-in persistent artifact storage. When you set the storage parameter to persistent in your API request, every generated image, video, or audio file is stored securely on our infrastructure. You receive a durable link that you can use immediately. This means you never have to build, maintain, or pay for your own storage solution. It is all handled for you, saving significant development time and operational cost.

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

Absolutely! HiAPI is built to be AI agent friendly. We provide Remote MCP tools, reusable Skills, and a comprehensive llms.txt file that agents can read to understand the entire API. You can simply paste the llms.txt prompt into your agent, and it will know exactly how to call models, manage tasks, and retrieve artifacts. This makes HiAPI an ideal backend for autonomous workflows in tools like Claude, Cursor, Codex, and many more.

How does pricing work and what is the cost?

HiAPI operates on a transparent, pay-as-you-go pricing model. Every model lists its price upfront on our website, so you know exactly what you will pay before you integrate. There are no hidden fees or complex tier structures. You simply sign up, receive free credits to get started, and then pay for the generations you use. This predictable cost structure makes it easy to estimate your expenses before a production launch and scale your usage as needed.
