What is HiAPI?
HiAPI provides a unified API gateway for AI-powered image, video, and audio generation, consolidating access to leading generative models such as GPT Image 2, FLUX 1.1 Pro, Nano Banana 2, Seedance 2.0, and MiniMax Music 2.6 into a single endpoint. Developers submit a task via a POST request, track its status, receive completion callbacks, and retrieve persistent artifact links without needing to build or maintain separate storage infrastructure. The platform supports availability-first routing, idempotency keys to prevent duplicate task creation, and cost-aware route selection, making it well-suited for production-grade generation workloads.
HiAPI is designed to be AI agent-friendly, offering MCP (Model Context Protocol) tools, reusable Agent Skills, and an llms.txt prompt so that agents built on Claude, Cursor, Codex, and similar platforms can discover and compose HiAPI capabilities with minimal setup. Pricing is fully transparent on a pay-as-you-go basis with no expiration on top-up balances, and new accounts receive $1 in free credit to explore up to 50 generations across all supported models.
Features
- Unified API Endpoint: One task-based POST endpoint supports every image, video, and audio generation model with a consistent request schema.
- Persistent Artifact Storage: Generated outputs are returned as durable links with no additional storage infrastructure required.
- Callback Support: Get notified on task completion via a callback URL, eliminating the need for polling.
- AI Agent Integration: Native support for MCP tools, Agent Skills, and llms.txt for seamless integration with Claude, Cursor, Codex, and other agents.
- Cost-Aware Routing: Select routes such as default, beta, or ext to compare costs and balance availability against price.
- Idempotency Keys: Prevent duplicate task creation on retries using the Idempotency-Key request header.
- Transparent Pay-Per-Use Pricing: Every model lists its price upfront with no hidden surge or token billing.
- Playground Access: Explore model parameters and example outputs on each model's page before writing code.
- Volume Discounts: Contact sales for volume-based rates on larger usage workloads.
- Wide Model Coverage: Supports GPT Image 2, FLUX 1.1 Pro, Nano Banana 2, Seedance 2.0, MiniMax Music 2.6, Seedream 5.0 Pro, and more.
Use Cases
- Generating product images for e-commerce using GPT Image 2 or FLUX 1.1 Pro via a single API call.
- Creating AI-generated marketing videos with cinematic quality using Seedance 2.0.
- Automating music and audio generation from text prompts using MiniMax Music 2.6.
- Building AI agent workflows that request, wait for, retrieve, and reuse generated media assets.
- Integrating multiple generative AI models into a SaaS platform without managing separate provider accounts.
- Running creative automation pipelines that pass persistent artifact links between tools and downstream processes.
- Testing and comparing different image or video generation models through the Playground before production integration.
- Reducing infrastructure overhead by leveraging persistent artifact storage returned directly from the API.
How It Works
Get a Free API Key
Sign up on HiAPI to receive $1 in free credit and obtain your Bearer API key from the dashboard.
Submit a Generation Task
Send a POST request to /v1/tasks with your chosen model, input parameters, desired storage type, and optional callback URL.
Track Task Status or Receive a Callback
Poll the task status via GET /v1/tasks/:id or wait for HiAPI to notify your callback URL when the task reaches its final state.
Retrieve Persistent Artifact Links
Access the durable output links returned in the task result to use, display, or pass the generated media to downstream tools or agents.
FAQs
-
Which models does HiAPI support?
HiAPI supports selected image, video, and audio generation models including GPT Image 2, FLUX 1.1 Pro, Nano Banana 2, Seedance 2.0, MiniMax Music 2.6, and Seedream 5.0 Pro, among others. The full list is available on the models page. -
How do persistent artifact links work?
Set the storage field to 'persistent' in your API request and generated outputs will be stored automatically. Durable links are returned in the task result so you can access or share them without building your own storage. -
Can I use callbacks instead of polling for task completion?
Yes. Provide a callback URL in your request and HiAPI will notify you when the task reaches its final state, eliminating the need to poll the task status endpoint. -
Can I try models before integrating?
Yes. Each model page includes a Playground where you can explore parameters and view example outputs before writing any code. -
Does the top-up balance expire?
No. Top-up balances on HiAPI never expire and work with every supported model. New accounts also receive $1 in free credit to generate up to 50 images.
