What Is HiAPI?

HiAPI is a unified API platform that provides developers with access to multiple artificial intelligence models through a centralized integration. It supports image, video, audio, and text generation, allowing applications to connect with different AI models without building a separate API integration for every provider.

The platform is designed for developers, application builders, and AI agent workflows. It provides a shared API key, model-specific pricing, task management, persistent output links, and integration options for AI coding assistants and agents.

Unified AI Model API

HiAPI brings multiple generative AI models together behind a unified API. Developers can explore available models and select the ones that suit their application requirements. Supported categories include image generation and editing, video generation, audio generation, and text-based AI models.

Rather than maintaining separate integrations for every supported model, developers can use HiAPI’s centralized infrastructure and account credentials. Individual models may still require different request parameters and endpoint formats.

AI Image Generation and Editing

HiAPI provides API access to image generation and editing models. Supported workflows include text-to-image generation, image-to-image editing, and reference-based image creation. Developers can select a model according to their requirements for image quality, output resolution, editing capabilities, and cost.

AI Video Generation

The platform also provides access to video generation models. Depending on the selected model, developers can build workflows involving text-to-video and image-to-video generation. Video tasks are processed through the asynchronous API, and pricing can depend on output duration, resolution, and model configuration.

AI Audio Generation

HiAPI supports audio-related models and workflows, including text-to-speech and music generation. Developers can integrate supported audio capabilities into applications using the platform’s centralized API access. Model availability and supported parameters vary by service.

Text Model Integration

HiAPI provides access to supported text models through OpenAI-compatible API endpoints. Developers can use these models for text-based application workflows, including conversational AI and other language-model tasks. The same account API key can be used across enabled text and media models.

Unified Asynchronous Task API

Image, video, and audio generation use a task-based asynchronous workflow. An application submits a generation request and receives a task identifier. It can then check the task status or configure a callback URL to receive notification when processing reaches its final state.

This approach is useful for generation tasks that take longer to complete than ordinary API requests. It allows developers to manage processing without keeping a request open while media is being generated.

Persistent Output Storage

HiAPI offers persistent artifact storage for generated outputs. When persistent storage is enabled, the platform returns durable links to completed results. This reduces the need for developers to build and maintain separate storage infrastructure for generated media.

AI Agent Integrations

HiAPI supports agent-oriented integration through a Remote Model Context Protocol (MCP) server and reusable Agent Skills. These options help compatible AI agents and coding assistants discover and interact with HiAPI capabilities.

The platform also provides an llms.txt integration index and documentation intended to make its API capabilities easier for AI development tools to understand.

Model Playground and Documentation

The HiAPI Playground allows developers to explore supported models, test parameters, and review example outputs before integrating a model into an application. Its documentation includes API references, model information, authentication guidance, and quick-start instructions.

Credit-Based Pricing

HiAPI uses a usage-based credit system rather than requiring a recurring subscription. The platform states that one US dollar purchases 2,000 credits. Each model has its own usage rate, with image generation generally charged per image, video generation per second, music per song, and speech generation per 1,000 characters.

New accounts receive 200 credits to explore the service. Actual generation costs vary according to the selected model, output resolution, duration, and available processing route. Developers can review model-specific rates before making requests.

Who Can Use HiAPI?

HiAPI is intended for software developers, AI application builders, automation specialists, and teams integrating generative AI into their products. It may be useful for projects that require access to several media and text models without maintaining multiple independent provider integrations.

Frequently Asked Questions

What does HiAPI provide?

HiAPI provides unified API access to supported image, video, audio, and text AI models through a centralized platform.

Does HiAPI require a separate API key for every model?

No. A single HiAPI account API key can access the models enabled for the account.

Does HiAPI support asynchronous generation?

Yes. Image, video, and audio generation use an asynchronous task API. Developers can check task status or receive completion notifications through callbacks.

Does HiAPI provide persistent storage?

Yes. Its persistent artifact feature returns durable links to generated outputs when the storage option is enabled.

Can AI agents connect to HiAPI?

Yes. HiAPI provides a Remote MCP server and Agent Skills for compatible AI agent workflows.

Is HiAPI free to use?

New accounts receive 200 credits. After those credits are used, additional usage requires purchasing credits according to the platform’s model-specific pricing.

Does HiAPI require a monthly subscription?

No. Its standard pricing model is based on usage credits rather than a required monthly subscription.
