HiAPI

HiAPI is a developer-first AI API platform that provides unified access to a curated selection of leading models for image, video, and audio generation. Rather than managing multiple API keys, disparate billing systems, and inconsistent request formats across different AI providers, developers can integrate a single endpoint to call models from OpenAI, ByteDance, Black Forest Labs, Google, and MiniMax. The platform is built around a task-based architecture where every generation request is submitted as a job, tracked through its lifecycle, and returned with persistent artifact links that eliminate the need for separate storage infrastructure. This design makes HiAPI particularly well-suited for production applications where reliability, cost predictability, and developer experience matter most. The platform supports OpenAI-compatible requests, unified billing with pay-as-you-go pricing, and offers multiple integration paths including direct API access, MCP tools for AI agents, reusable Skills for common workflows, and llms.txt for agent discovery. With support for text-to-image, image-to-image, video generation, music and audio creation, HiAPI targets developers building AI-powered applications, AI agent developers who need composable model access, and teams that want to evaluate and ship with multiple models without committing to a single provider upfront. The platform emphasizes quality over quantity in its model selection, featuring only production-grade models with transparent pricing listed before integration.

Unified Task API with Persistent Artifacts

Every generation request follows the same simple lifecycle: submit a job, check its status, receive a callback, and retrieve stored artifacts. The POST /v1/tasks endpoint accepts model, input, route, storage, and callback parameters, returning a task ID that can be used for deduplication via idempotency keys. Setting storage to persistent returns low-cost durable artifact links, so developers do not need to build or maintain separate storage systems for generated outputs. This single workflow applies consistently across image, video, and audio models.

One API Key for Multiple Leading Models

Developers access models like GPT Image 2, Seedream 5.0 Pro, FLUX 1.1 Pro, Seedance 2.0, and MiniMax Music 2.6 through a single API key and a unified endpoint. The platform validates model-specific parameters per request, so each call gets the correct schema for the chosen model while maintaining a consistent interface. This eliminates the overhead of managing separate credentials, documentation, and integration patterns for each provider.

AI Agent Ready Integration

HiAPI provides multiple integration paths designed for both human developers and autonomous AI agents. MCP tools expose HiAPI workflows as agent-accessible tools. Skills offer reusable agent instructions for common generation tasks. llms.txt provides a machine-readable documentation index that agents can parse to understand available models and APIs. This makes HiAPI directly usable from agent frameworks like Claude, Cursor, and Codex without custom integration code.

Production-Grade Reliability and Routing

The platform is built for real workloads with availability-first routing, automatic callbacks, and 24/7 support. Developers can specify optional routes such as beta or ext to access different model versions or deployment tiers. Callbacks notify applications on task completion instead of requiring polling, reducing latency and infrastructure costs. The idempotency key mechanism ensures safe retries without duplicate task creation.

Building AI-Powered Content Generation Applications

Developers building applications that generate images, videos, or audio can integrate HiAPI with a single endpoint and one API key. For example, a social media scheduling tool can generate GPT Image 2 images for posts, Seedance 2.0 videos for stories, and MiniMax Music 2.6 background tracks, all through the same task API. Persistent artifact links mean generated content is immediately accessible without building separate storage.

AI Agent Workflows for Creative Production

AI agents can use HiAPI through MCP, Skills, or llms.txt to compose multi-modal generation workflows. An agent tasked with creating a product launch campaign can generate product images with Seedream 5.0 Pro, produce a promotional video with Seedance 2.0, and compose background music with MiniMax Music 2.6, all by calling the same unified API. The agent can track task statuses and receive callbacks to coordinate the workflow.

Prototyping and Evaluating Multiple Models

Teams evaluating which AI model best suits their use case can quickly compare outputs from different providers through HiAPI. A design team testing image generation can submit the same prompt to GPT Image 2, FLUX 1.1 Pro, and Seedream 5.0 Pro, comparing results for text rendering quality, style fidelity, and generation speed. Transparent pricing allows cost comparison before committing to a model for production.

Production Media Pipelines with Cost Control

Media companies and marketing teams running high-volume generation workflows benefit from HiAPI's predictable pay-as-you-go pricing and persistent storage. A video production pipeline can generate Seedance 2.0 clips with native audio, submit callback URLs to trigger downstream editing processes, and rely on durable artifact links for asset management. The unified billing system provides a single invoice for all model usage.

How does the unified task API work?

The task API uses a single POST /v1/tasks endpoint for all models. You pass the model name, model-specific input parameters, and optional fields for route, storage, and callback. The API returns a task ID that you can use to check status or retrieve results. Setting storage to persistent provides durable artifact links. Using an idempotency key ensures that retries do not create duplicate tasks.

Which models are currently available on HiAPI?

HiAPI offers curated models for image, video, and audio generation. Image models include GPT Image 2 from OpenAI, Seedream 5.0 Pro and FLUX 1.1 Pro for high-fidelity generation, and Nano Banana 2 from Google for fast generation with strong character consistency. Video models include Seedance 2.0 from ByteDance for cinematic video with native audio. Audio models include MiniMax Music 2.6 for turning prompts into complete songs.

How do I get started with a free API key?

You can sign up on the HiAPI website to get a free API key and receive up to $1 in free credits to start testing. The platform offers a free tier that allows you to evaluate models, test the task API workflow, and verify persistent artifact links before committing to paid usage. Documentation provides curl, JavaScript, and Python examples for the first API call.

Is HiAPI compatible with OpenAI SDKs and libraries?

Yes, HiAPI supports OpenAI-compatible requests, which means you can use existing OpenAI client libraries and SDKs with minimal configuration changes. This compatibility extends to request formats, authentication patterns, and response structures, making migration straightforward for teams already using OpenAI APIs. The unified billing system applies regardless of which model you call.
