HiAPI

What is HiAPI?

HiAPI is a unified API gateway that provides access to leading generative AI models for image, video, and audio creation. It simplifies development by offering a single endpoint and schema to call multiple models, such as GPT Image 2, Nano Banana 2, Seedance 2.0, FLUX 1.1 Pro, and MiniMax Music 2.6. HiAPI focuses on production-grade reliability with features like persistent artifact storage, task tracking, callbacks, and availability-first routing. It is designed for developers and AI agents, offering tools like MCP, Skills, and llms.txt for easy integration. Users get a free API key with up to $1 in credits to start, and pay-as-you-go pricing with no expiration on purchased credits.

Main Features

- Unified API: One endpoint and schema for all image, video, and audio generation models.

- Persistent Storage: Outputs are returned as durable links, eliminating the need to build and maintain storage.

- AI Agent Friendly: Supports MCP, Skills, and llms.txt for seamless integration with agents like Claude, Cursor, and Codex.

- Production-Grade: Availability-first routing, callbacks, and 24/7 support ensure reliable performance.

- Transparent Pricing: Each model lists its price upfront, with volume discounts available for larger usage.

- Task-Based API: Submit jobs, check status, receive callbacks, and retrieve stored artifacts through a simple lifecycle.

- Cost-Aware Routing: Use the route field to select default, beta, or ext routes and compare costs clearly.

Use Cases

- AI Video Tools: Teams can test video models quickly and keep generated assets reachable without building storage for each provider.

- Creative Automation: Persistent artifact links enable easy passing of outputs between campaign tools, review, and downstream automation.

- Agent Workflows: A task API with callbacks gives agents a clean way to request, wait, retrieve, and reuse generated media.

- Product Photography: Generate high-quality product images for e-commerce with models like GPT Image 2 and FLUX 1.1 Pro.

- Music and Audio Generation: Create songs and audio from prompts and lyrics using MiniMax Music 2.6.

- Rapid Prototyping: Use the playground on each model page to explore parameters and example outputs before writing code.

Supported Languages

- English (primary interface and documentation)

- The API itself is language-agnostic; models support various input languages depending on the specific model (e.g., GPT Image 2 handles multilingual text rendering, including CJK characters).

Frequently Asked Questions

- Which models does HiAPI support?

HiAPI supports selected image, video, and audio generation models. Browse the full list on the models page.

- How do persistent artifact links work?

Set storage to persistent and generated outputs are stored for you and returned as durable links in the task result.

- Can I use callbacks instead of polling?

Yes. Provide a callback URL and HiAPI notifies you when the task reaches its final state, so you skip polling.

- Can I try models before integrating?

Yes. Use the Playground on each model page to explore parameters and example outputs before writing code.
