HiAPI

HiAPI is a developer-first AI API platform designed to eliminate the complexity of integrating multiple generative AI models for image, video, and audio generation. Instead of managing separate API keys, billing accounts, and authentication schemes for each model provider, you get one unified API key and endpoint that works across a curated selection of leading models from companies like OpenAI, ByteDance, Google, Black Forest Labs, and MiniMax. The core problem HiAPI solves is fragmentation: developers waste time learning different request schemas, handling inconsistent error responses, and building custom storage solutions for generated outputs. HiAPI delivers persistent artifact links automatically, so every image, video, or audio file you generate comes back as a durable URL with no extra infrastructure work. The platform is built for production workloads with availability-first routing, configurable callbacks, and 24/7 support. It also supports OpenAI-compatible requests for drop-in replacements in existing codebases. Beyond traditional API integration, HiAPI is designed for AI agents through MCP (Model Context Protocol) tools, reusable agent Skills, and llms.txt documentation that lets agents discover and call models autonomously. Whether you are building a content generation pipeline, a creative tool, or an agent-based workflow, HiAPI simplifies access to state-of-the-art generative models with transparent pay-as-you-go pricing and unified billing.

Unified API with One Schema

HiAPI provides a single endpoint and request schema for every image, video, and audio model on the platform. You pass the base model name and model-specific input parameters, and the API handles routing, validation, and execution. This eliminates the need to learn different request formats for each provider. The same lifecycle applies to all tasks: submit a job, check status, receive callbacks, and retrieve stored artifacts. This consistency reduces integration time from days to minutes and makes it trivial 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, maintain, or pay for separate storage infrastructure. When you set the storage parameter to persistent, the API stores the generated file and returns a URL that remains accessible. This is especially valuable for production applications where you need to serve generated content to users without worrying about file expiration or storage costs. The feature works across all model types, including images, videos, and audio files.

AI Agent Friendly Integration

HiAPI is built for the age of AI agents. It supports MCP (Model Context Protocol) tools that agents can discover and call directly, reusable Skills that provide step-by-step instructions for common workflows, and llms.txt documentation that gives agents complete context about available models and APIs. This means you can wire up HiAPI into agents like Claude, Cursor, or Codex with minimal configuration. Agents can autonomously select the right model, submit generation tasks, and retrieve results using natural language instructions.

Production-Grade Reliability

HiAPI is designed for real-world workloads with availability-first routing that automatically directs requests to healthy model endpoints. The platform supports idempotency keys to prevent duplicate task creation on retries, configurable callbacks that notify your application when a task completes, and 24/7 support for critical issues. This infrastructure ensures that your generative AI pipelines remain stable and predictable under load, whether you are running a few hundred or millions of requests per month.

Automated Content Generation Pipelines

Marketing teams and content platforms can use HiAPI to build automated pipelines that generate images, videos, and audio at scale. For example, an e-commerce site could automatically create product images with different backgrounds, generate promotional video clips, and produce voiceover audio, all through the same API. The persistent artifact links make it easy to serve generated content directly to end users without additional storage infrastructure. The callback system lets you trigger downstream actions like publishing or moderation as soon as generation completes.

Creative Tool Integration

Design applications and creative suites can integrate HiAPI to give users access to multiple generative AI models without managing multiple provider accounts. A design tool could offer text-to-image generation with Seedream 5.0 Pro, image editing with GPT Image 2, and background music generation with MiniMax Music 2.6, all behind a single API key. Users benefit from a consistent experience, and developers avoid the overhead of maintaining separate integrations for each model provider.

AI Agent Workflows

Developers building AI agents can use HiAPI's MCP tools and Skills to give agents the ability to generate visual and audio content autonomously. An agent could generate an image to illustrate a concept, create a short video to explain a process, or compose background music for a presentation. The llms.txt documentation allows agents to discover available models and parameters without human intervention, making it possible to build fully autonomous content creation systems.

Real-Time Content Moderation and Editing

Platforms that need to generate and then quickly review or edit content can leverage HiAPI's task-based architecture. A social media platform could generate user-requested images, receive callbacks when generation completes, and then pass the persistent artifact links through moderation pipelines. If content needs editing, the same API supports image-to-image generation for refinement. This workflow ensures that generated content is reviewed before publication while maintaining a smooth user experience.

How do I get started with HiAPI?

Sign up on the HiAPI website to get a free API key and up to $1 in free credits. You can start making requests immediately using the unified API endpoint. The platform supports curl, JavaScript, and Python with examples provided in the documentation. For a quick start, send a POST request to /v1/tasks with your model name and input parameters. The response includes a task ID that you can use to poll for results or receive callbacks when processing completes.

What models are available on HiAPI?

HiAPI offers a curated selection of leading generative models. For image generation and editing, you can use GPT Image 2, Seedream 5.0 Pro, FLUX 1.1 Pro, and Nano Banana 2. For video generation, Seedance 2.0 from ByteDance provides cinematic video with native audio. For audio, MiniMax Music 2.6 turns prompts and lyrics into complete songs with instrumental mode. The platform continues to add new models, and you can explore the full list on the models page.

How does pricing work on HiAPI?

HiAPI uses transparent pay-as-you-go pricing. Each model lists its price per request or per unit of output on the model details page, so you can estimate costs before integrating. There are no monthly subscription fees or minimum commitments. You only pay for what you use, and you can review your usage and billing in the dashboard. The free credits give you enough to test models and build prototypes before committing to production usage.

Can I use HiAPI with existing OpenAI-compatible code?

Yes, HiAPI supports OpenAI-compatible requests, making it easy to drop into existing codebases that already use OpenAI's API format. You can replace your OpenAI API key and endpoint with HiAPI's credentials and start accessing additional models without rewriting your integration code. This compatibility extends to request structure, authentication headers, and response formats, minimizing migration effort.

HiAPI operates on a transparent pay-as-you-go pricing model with no monthly subscription fees or minimum commitments. Each model has its own per-request or per-unit pricing listed on the model details page. New users receive up to $1 in free credits upon signup to test models and build prototypes. You can monitor your usage and estimated costs in the dashboard before production launch. Specific pricing for each model, including Seedream 5.0 Pro, GPT Image 2, and others, is available on the HiAPI website under each model's details page.
