## Overview
HiAPI is an AI API gateway that puts image, video, audio and text generation models from several providers behind one API key and one account balance. Its catalog includes GPT Image 2.5, Nano Banana 2, Seedream 5.0 Pro and FLUX for images; Veo 3.1, Seedance 2.5 and Kling 3.0 for video; ElevenLabs v3 and MiniMax Music for voice and music; and text models such as Claude Sonnet 4.6 and DeepSeek V4 through OpenAI-compatible Chat Completions and Responses endpoints.

It is built for developers and AI agents. Media jobs go through a single asynchronous task endpoint: you send a model name and its input, then poll the task or wait for a callback. Outputs can be stored as persistent links, so there is no storage to build yourself, and idempotency keys prevent duplicate billing when a request is retried. Official SDKs cover Python, Node.js, Go and Java, and agents can connect through MCP, Skills or llms.txt.

Pricing is pay-as-you-go with credits. Each model shows its price per image, per second of video or per song before you call it, and new accounts receive 200 free credits. One limitation: HiAPI is an aggregation layer, so the models themselves come from other providers, and media generation uses an async task flow rather than a single blocking call.
## Key Features
- Unified async task API for image, video and audio models
- OpenAI-compatible Chat Completions and Responses endpoints for text models
- Persistent storage of generated outputs as durable links
- Completion callbacks instead of polling
- Idempotency keys to avoid duplicate tasks on retry
- Route selection (default, beta, ext) to compare cost per model
- Official SDKs for Python, Node.js, Go and Java
- MCP server, Agent Skills and llms.txt for AI agents
- Web playground and per-model public pricing

## Use Cases
- Add image generation to an app without separate provider accounts
- Generate video clips with models like Veo 3.1 or Seedance from one API
- Create music and multi-speaker voice audio programmatically
- Give AI coding agents access to generative models via MCP
- Compare model costs before launching a production workload
