HiAPI

HiAPI is a developer-first AI API platform designed to simplify how you integrate image, video, and audio generation into your applications. At its core, HiAPI solves a fundamental problem: instead of managing separate API keys, billing accounts, and documentation for every AI model provider, you get one unified gateway. You use a single API key, one consistent endpoint, and one billing system to access leading generative models from companies like OpenAI, ByteDance, Black Forest Labs, and MiniMax. The platform is built for developers who need production-grade reliability, persistent storage for generated outputs, and the flexibility to work with both traditional code and modern AI agents. HiAPI supports text-to-image, image-to-image, video generation, and audio creation workflows. Every request follows the same task lifecycle: you submit a job, track its status, receive callbacks when processing completes, and retrieve durable artifact links without building your own storage infrastructure. The API is OpenAI-compatible, meaning if you already know how to call OpenAI models, you already know how to use HiAPI. Pricing is transparent and pay-as-you-go, with no hidden fees or minimum commitments. Whether you are building a content creation tool, an AI agent workflow, or a production application that needs reliable media generation, HiAPI provides the foundational infrastructure to ship faster and scale confidently.

Unified API for All Models

HiAPI provides one endpoint and one request schema for every image, video, and audio model it supports. Instead of learning different API formats for each provider, you pass a model name like "gpt-image-2/text-to-image" or "seedream-5.0-pro/text-to-image" to the same POST /v1/tasks endpoint. This unified approach drastically reduces integration time and maintenance overhead, allowing your team to switch or add models without rewriting code.

Persistent Artifact Storage

Every output generated through HiAPI comes back as a durable, persistent link. You do not need to build, manage, or pay for your own storage infrastructure to host AI-generated images, videos, or audio files. Simply set the "storage" parameter to "persistent" in your request, and HiAPI handles the rest. This feature is especially valuable for applications that need to serve generated content to end users reliably over time.

Production-Grade Task Management

HiAPI uses an asynchronous task-based architecture designed for real-world production loads. When you submit a job, you receive a task ID immediately. You can poll for status, or set up a callback URL to get notified when processing completes. The platform supports idempotency keys, meaning you can safely retry requests without creating duplicate tasks. This foundation ensures your application can handle network failures and retries gracefully.

AI Agent Friendly Integration

HiAPI is built for the age of AI agents. It supports Model Context Protocol (MCP), reusable Skills, and an llms.txt file that agents can read to understand the platform. This means you can wire up HiAPI into tools like Claude, Cursor, or Codex with minimal effort. Agents can discover available models, understand the API schema, and compose workflows autonomously, making HiAPI a natural fit for autonomous and semi-autonomous development pipelines.

Building a Content Generation Platform

If you are building a website or application that lets users generate images, videos, or music from text prompts, HiAPI gives you the infrastructure to do it at scale. You integrate once with the unified API, offer multiple models from different providers, and let users pick the style or quality they need. Persistent storage means you can serve generated content directly to users without building your own file hosting system. The callback mechanism lets you update users in real time when their generation is ready.

Creating AI Agent Workflows

Developers building autonomous agents that need to generate media as part of a larger task can use HiAPI as the media generation layer. An agent tasked with creating a marketing campaign, for example, can call HiAPI to generate images, then use the returned artifact links in other tools. Because HiAPI supports MCP and Skills, agents can discover and call the API without hardcoded integration steps. This makes HiAPI a foundational building block for complex agent pipelines.

Prototyping and Rapid Experimentation

For teams that want to test different AI models before committing to a specific provider, HiAPI removes the friction of signing up for multiple services. You get one API key, one billing account, and access to multiple models. You can compare outputs from GPT Image 2, Seedream 5.0 Pro, FLUX 1.1 Pro, and others using the same request format. This experimentation phase becomes much faster, and you can make data-driven decisions about which model best fits your use case.

Production Media Generation Services

Applications that need to generate media reliably under load, such as e-commerce product image generators, social media content tools, or video creation platforms, benefit from HiAPI's production-grade design. Availability-first routing ensures requests are handled even if one model provider has issues. Callbacks and idempotency keys provide the reliability guarantees that production systems require. Transparent pricing lets you estimate costs accurately before scaling up.

How do I get started with HiAPI?

You can sign up for a free account on the HiAPI website and receive up to one dollar in free credits to test the platform. After signing up, you will get an API key. You can then make your first request using the provided curl, JavaScript, or Python examples in the documentation. The unified API means you can start generating images, videos, or audio with just a few lines of code.

What models are currently available on HiAPI?

HiAPI supports a curated selection of leading generative models. For image generation and editing, you have access to GPT Image 2, Seedream 5.0 Pro, FLUX 1.1 Pro, and Nano Banana 2. For video, there is Seedance 2.0 from ByteDance. For audio, MiniMax Music 2.6 is available for generating songs from prompts and lyrics. The platform continues to add new models, and you can explore all available options on the models page.

How does pricing work on HiAPI?

HiAPI uses a pay-as-you-go pricing model with transparent costs listed for each model. You can review the price per generation before you integrate, allowing you to estimate your costs accurately. There are no monthly minimums or hidden fees. You receive free credits upon signup to test the platform, and then you pay only for what you use. Billing is unified across all models, so you receive one invoice for all your usage.

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

Yes, HiAPI is designed to be AI agent friendly. It supports Model Context Protocol (MCP) for agent-accessible tools, reusable Skills for common workflows, and an llms.txt file that agents can read to understand the platform. You can paste the llms.txt prompt into your agent so it understands HiAPI models and APIs. The agent can then choose between Skills, Remote MCP, or direct API integration as the best setup path for your specific use case.
