PRODUCT OVERVIEW
What is HiAPI?
HiAPI is a developer-focused API gateway that aggregates leading generative AI models from providers such as OpenAI, Google, Black Forest Labs, ByteDance, Alibaba, and ElevenLabs behind a single endpoint. Through one task-based API, developers submit jobs, poll status or receive callbacks, and retrieve outputs as durable links via persistent storage. It covers text-to-image and image-to-image, text-to-video and image-to-video, music, speech, and text models, with MCP, Skills, and llms.txt integration paths for AI agents. Usage is billed per task with no minimums, and new accounts receive 200 Credits plus a free API key to start.
How to use HiAPI

- 2
Submit a generation task
Send a POST request to /v1/tasks with the model name, model-specific input parameters, and an optional route.
- 3
Track status or use callbacks
Poll the task detail endpoint or provide a callback URL so HiAPI notifies you when the task reaches its final state.
