HiAPI
Generate high-quality AI images, videos, and music through a single unified API with persistent storage and callback support built for modern developers.
About HiAPI
HiAPI acts as a unified generative AI gateway, consolidating leading text, image, video, and audio models from top-tier providers like OpenAI, Google, ByteDance, Alibaba, and Black Forest Labs. Instead of managing dozens of separate SDKs, API keys, and billing accounts, developers gain instant access to flagship models including GPT Image 2, FLUX 1.1 Pro, Seedance 2.0, and MiniMax Music through a single standard endpoint. This streamlined approach eliminates the typical overhead associated with infrastructure setups, enabling rapid prototyping and production deployment of AI-driven media generation workflows. At the technical level, the platform utilizes an asynchronous task execution lifecycle where requests are sent via a standardized POST endpoint. To prevent double-billing and handle network retries gracefully, the API integrates optional idempotency keys. Once a job is submitted, developers can opt for cost-effective persistent storage, allowing generated media artifacts to remain accessible via durable links directly from the task result without any extra storage setup. To optimize system resources and remove the need for continuous polling, HiAPI supports webhooks and callbacks that notify client servers the moment a task reaches its final state. HiAPI is specifically designed for software engineers, product teams, and AI agent developers who require reliable media generation infrastructure. Creative automation agencies can programmatically render dynamic marketing assets, while AI video SaaS startups can quickly benchmark and swap different underlying video models like Seedance or Wan without rewriting their integration layer. The API is also uniquely built for autonomous AI agents, offering pre-configured Model Context Protocol (MCP) integrations, reusable Agent Skills, and structured llms.txt index files to allow LLMs to directly discover and trigger media tasks. What sets the service apart from traditional serverless GPU hosting is its combination of persistent media hosting, transparent output-based pricing, and availability-first routing. Rather than charging per token or billing for active GPU runtime, the platform offers absolute pricing per task or per second, allowing companies to predict costs accurately. Additionally, its routing mechanism prioritizes stable and reliable access over simply choosing the cheapest alternative route, ensuring enterprise-grade uptime. With 24/7 technical support and ready-made developer tools, it lowers the barrier to deploying media workflows at scale.
Pros & cons
Pros
- Offers a $1 signup bonus providing up to 50 free image generations without upfront payment.
- Persistent storage option returns durable asset links, eliminating the need to build custom hosting paths.
- Idempotency keys prevent duplicate tasks and double-billing on network retries.
- Built-in agent support with MCP tools, Skills, and an llms.txt index file.
- Provides availability-first routing to ensure reliable uptime for long-running production tasks.
Cons
- GPT Image 2 speed is a step backward compared to older versions, requiring about 107 seconds per generation.
- GPT Image 2 lacks support for transparent backgrounds, meaning custom cutouts require external tools.
- A completely key-less, free-tier production API is not offered due to GPU hosting costs.
Use cases
- AI Video SaaS teams can rapidly integrate and compare different video models like Seedance or Wan without changing their base API schemas.
- Creative automation engineers can utilize persistent artifact links to seamlessly transfer generated assets between campaign tools and review pipelines.
- AI Agent developers can configure autonomous agents using the llms.txt prompt to request, wait for, and retrieve media assets via callbacks.
- Indie developers can build prototypes cheaply using the pay-as-you-go top-up model with balance credits that never expire.

FAQs
Which models does HiAPI support?
HiAPI supports selected image, video, and audio generation models from top-tier providers. Featured models include GPT Image 2, Nano Banana 2, FLUX 1.1 Pro, Seedance 2.0, and MiniMax Music 2.6.
How do persistent artifact links work?
When you set the storage parameter to persistent in your API call, generated outputs are safely hosted by HiAPI. The API then returns durable links in your task result so you do not have to build your own storage.
Can I use callbacks instead of polling?
Yes, you can avoid continuous API polling. By providing a callback URL in your request payload, HiAPI will automatically notify your system once the generation task reaches its final state.
Can I try the models before integrating them into my code?
Yes, you can test models before writing code. HiAPI provides an interactive Playground on each individual model page where you can explore parameters and view sample outputs.
Does the top-up balance expire?
No, your purchased top-up balance has no expiration date. You can purchase starter, popular, or volume packages and use the funds whenever you need them across any of the available models.
Is there any volume-based discount for larger workloads?
Yes, larger production workloads can qualify for custom volume-based rates. Developers and enterprises can contact the sales team directly at hi@hiapi.ai to discuss specialized pricing.
How does the idempotency feature work?
By sending an Idempotency-Key in the request header, you can safely retry API requests. If a request is retried with the same account and key, only one task is created, returning the original taskId.
