HiAPI is an API aggregation gateway for AI generation capabilities. Its core approach is to use a single key to access image, video, music, and text generation APIs. Users can browse models, compare prices, try a free image generator, and complete integration through one API. Signing up gives 200 Credits.
Main capabilities: You can call multiple image, video, and audio generation models with the same API, including image generation, image editing, music generation, and video workflows. Models listed on the platform include GPT Image 2.5 Flare (speed-focused everyday generation and reference image editing, from $0.050/image), GPT Image 2.5 Sunburst (complex designs and precise local edits, from $0.030/image), OpenAI image generation and editing (sharp text rendering, from $0.036/image), Google Gemini Flash image model (fast, strong character consistency), Seedream 5.0 Pro (ByteDance flagship image generation and editing), ByteDance video generation (clips up to 30 seconds, synchronized audio, multimodal reference), Black Forest Labs video generation (storyboarding, continuation, synchronized audio, up to 20 seconds), ByteDance cinematic video (native audio, multi-shot consistency), Google flagship video generation, Kuaishou cinematic video (motion control and physical consistency), Black Forest Labs high-fidelity image generation, MiniMax Music 2.6 (from $0.210/song, generates complete songs from prompts and lyrics, including instrumental-only mode), Qwen Image 2.0 Pro (from $0.107/image, Alibaba's professional image model, strong typography and prompt adherence), Alibaba video generation (flexible duration, 1080p output), Grok Imagine 1.5 (xAI image-to-video), and multi-speaker dialogue generation (covering more than 70 languages, from $0.125/1K chars).
How to use: All generation workflows share a single task API. Submit a task, check status, receive callbacks, and retrieve stored artifacts, with a consistent lifecycle. Request fields include: model (required; passing the base model name is enough to call any model through the same endpoint), input (required,Model-specific parameters, validated per request), route (optional, such as beta or ext; omit it or pass default for the default route), storage (optional; set to persistent to get low-cost persistent output links), callback (optional; notify on task completion instead of polling). Integration methods include API documentation, MCP, Skills, and llms.txt, making it easy for developers and agents to discover, call, and combine HiAPI. The platform provides llms.txt prompts that let agents understand HiAPI models and APIs, then choose Skills, Remote MCP, or direct API access. Each model page provides a Playground so you can explore parameters and example outputs before writing code.
Use cases: production-oriented generative workloads, providing reliable access, persistent outputs, task tracking, and support for long-running image, video, and audio tasks. Suitable for teams building AI video tools, creative automation, and agent workflows. The platform emphasizes availability-first routing, persistent output links, long-task optimization, and production integration and operations coverage.
Cost and limits: pricing is listed in advance for each model, making it easy to estimate usage before integration. You can use the route field to select available routes such as default, beta, and ext and compare costs. For larger usage, contact sales for usage-based rates. Related content mentions: HiAPI is an image and video generation API gateway, with FLUX 1.1 Pro, Nano-Banana, GPT-Image-2, Qwen-Image, Wan2.7, Seedance, and HappyHorse behind a single Bearer-authenticated endpoint; fixed per-task pricing, with gpt-image-2-beta at $0.02, Nano-Banana or flux-1.1-pro at $0.05, and 1080p Seedance clips up to $0.823; no token billing, no peak surcharges; all generation goes through the asynchronous POST /v1/tasks endpoint, with text-to-image, image-to-image, text-to-video, and image-to-video having the same shape; most image models accept input.prompt + input.aspect_ratio; qwen-image-2.0 uses a DashScope-style nested schema with literal pixel dimensions and requires a model-to-payload adaptation mapping.
Also noted: OpenAI's current direct API model ID is gpt-image-2, while gpt-image-1 and gpt-image-1.5 are previously deprecated image models; new HiAPI integrations should use gpt-image-2/text-to-image or gpt-image-2/image-to-image via POST /v1/tasks; retired HiAPI Pro IDs map to the current text-to-image and image-to-image IDs, and Pro should not be retained in new code. Related reviews mention: GPT Image 2 on HiAPI costs $0.03/$0.04/$0.06 for 1K/2K/4K respectively, the same for text-to-image and image-to-image; GPT Image 2's text rendering is a clear upgrade, its realism is strong for product photography and detailed interior scenes, portraits occasionally look overly symmetrical, each image takes about 107 seconds, slower than GPT Image 1.5's 18–36 seconds, and it does not support transparent backgrounds. Another test mentions that with a key, GPT Image 2 costs $0.007 per image on HiAPI.
