AI Tool Profile
HiAPI
HiAPI is a unified API for image, video, audio and text models, with one API key, async tasks with callbacks, persistent artifact links and pay-as-you-go credits.
Description of HiAPI
HiAPI is a unified API platform for generative AI. With one API key, developers can call image, video, audio and text models from many providers, including GPT Image 2.5, Nano Banana 2, Seedream 5.0, Seedance 2.5, Veo 3.1, Kling, FLUX, MiniMax Music and ElevenLabs, without building a separate integration for each one. The pricing page lists 123 models across image, video, audio and text.
Text models use OpenAI-compatible Responses and Chat Completions endpoints. Image, video and audio jobs run through one asynchronous task API: you create a task, then poll its status or receive a callback when it finishes, and outputs can be stored as persistent artifact links. Billing is pay-as-you-go credits, with image prices on the homepage starting from $0.025 per image, and new accounts get 200 credits on sign-up.
Features of HiAPI
- One API key and one schema for image, video, audio and text models, with a model marketplace, live per-model pricing and a browser Playground to try each model first.
- A unified async task API with status polling or completion callbacks, plus persistent storage that returns durable links for generated outputs.
- Agent-ready integration paths: an MCP server, Agent Skills, llms.txt and a Python SDK, alongside public API reference docs.
Frequently asked questions
How much does HiAPI cost?
HiAPI uses pay-as-you-go credits with a separate price for each model and output size, listed on the pricing page. For example, GPT Image 2.5 Flare starts at $0.025 per 1K image. New accounts get 200 credits on sign-up. The terms of service say purchased balance is non-refundable but never expires.
Can I use callbacks instead of polling?
Yes. Provide a callback URL when you create a task, and HiAPI notifies your endpoint when the task reaches its final state, so you do not need to poll.
How do persistent artifact links work?
Set the task storage option to persistent and the generated outputs are stored for you and returned as durable links in the task result, so you can pass them to other apps or agent workflows without building your own storage.

| Can a general AI assistant replace it? | Not a chat app; an API reseller. Alternatives are fal.ai, Replicate, OpenRouter or each model vendor's own API — compare per-generation prices, which load live on the pricing page. |
