HiAPI
One API for image, video, and audio generation with persistent artifact storage.
HiAPI is a solid choice for teams wanting one API to reach diverse image, video, and audio models, especially in agentic workflows. Persistent storage and callbacks are real time-savers. Just be ready to pay per task and accept a curated catalog. If you need on-prem deployment or exhaustive model coverage, consider fal.ai or Replicate directly, but for unified access with MCP and llms.txt support, HiAPI is worth the trade-off.

Skip HiAPI if you need a free tier beyond a small trial credit, require on-premises deployment, or expect access to every niche model on the market rather than a curated catalog.
After the initial 2,000 credits, you pay per model per generation—there's no free tier, so costs add up quickly with volume.
HiAPI's pay-as-you-go pricing fits startups and teams that need flexibility without long-term contracts. It's competitive with fal.ai and Replicate for per-generation costs, though you pay a premium for the convenience of a unified API and persistent storage. If you're a high-volume user, volume discounts can bring costs in line with direct provider APIs.
In short
HiAPI — One API for image, video, and audio generation with persistent artifact storage. Best for Developers building generative AI applications with multiple models, Teams needing multi-model access without managing separate provider keys, AI agent developers using MCP or llms.txt for autonomous media generation.

About HiAPI
HiAPI is a unified AI API gateway that lets developers call over 40 leading generative models for image, video, and audio through a single endpoint. You submit a task with one API key, and HiAPI handles the rest: durable output links, optional callbacks, and cost-aware routing. It's built for production workloads, not just experiments, with 24/7 support and transparent per-model pricing so you know what you'll pay before you integrate. Teams building AI video tools, creative automation, and agent workflows use it to skip the overhead of managing multiple provider SDKs and storage backends. The platform is especially agent-friendly. It ships with MCP server support, Agent Skills for common workflows, and an llms.txt index so AI agents can discover and call HiAPI autonomously. You can paste the llms.txt prompt into Claude, Cursor, or Codex, and the agent can figure out whether to use Skills, Remote MCP, or the direct API. This makes HiAPI a practical pick for developers automating media generation inside agentic systems. Under the hood, HiAPI's task lifecycle is simple: POST a request with a model name and input, get a task ID, then poll or receive a callback when it's done. Idempotency keys prevent duplicate tasks on retries, and persistent storage means generated artifacts stay reachable through the returned links—no extra storage infrastructure to build. The platform also offers a Playground for each model so you can test parameters before writing code. HiAPI also supports text models via an OpenAI-compatible API, including DeepSeek-V4-Pro with 1M context. It offers a free API key with up to 2,000 credits, and pricing is per-model with transparent rates. HiAPI is a good fit if you need multi-model access without juggling separate provider accounts. But it's not for everyone: there's no free tier beyond a trial credit, and the model set is curated rather than exhaustive. Compared to managing raw provider APIs, HiAPI wins on convenience and storage, but you're trading that for a dependency on their gateway and pricing.
Behind the Verdict
HiAPI positions itself as a production-ready gateway for generative media, and it largely delivers on that promise. The core value is simplicity: one endpoint for dozens of models, persistent artifact links, callbacks, and idempotency keys out of the box. This is a genuine time-saver for developers who would otherwise stitch together multiple provider SDKs and build their own storage layer. The agent-friendly angle is a standout. The MCP server, Agent Skills, and llms.txt index are not just marketing fluff—they're concrete integrations that let Claude, Cursor, or Codex autonomously discover and call HiAPI. This is a differentiator that resonates with the growing agentic AI trend. Pricing is transparent, with per-model rates listed clearly. You get up to 2,000 free credits on signup, but after that it's strictly pay-as-you-go. There's no free tier to speak of, and no on-prem option, which limits its appeal for hobbyists and security-sensitive enterprises. The model catalog is curated but extensive, covering major providers like OpenAI, Google, ByteDance, Black Forest Labs, and ElevenLabs. The recent addition of DeepSeek-V4-Pro with 1M context extends its text model support, making it a more complete gateway for multimodal workflows. Weaknesses: you're dependent on HiAPI's gateway, so any downtime or pricing changes affect you. Some models are only available on certain routes (e.g., Seedance 2.0 ext route removed 2k option). Audio models are still limited, and there's no free tier beyond trial credits. Where it fits: startups and product teams building AI features that need to iterate across multiple models quickly. Where it doesn't: enterprises needing on-prem deployment, or teams requiring every niche model under the sun. Overall, HiAPI is a pragmatic choice, not a revolutionary one. It's a well-executed convenience layer, and for many teams that convenience is worth the extra cost.

Real-world workflow fit
Concrete scenarios for the personas HiAPI actually fits — and what changes day-one when you adopt it.
You sign up, add credits, and use the Unified Async API to generate images with GPT Image 2. You set storage to persistent so links don't expire, and use callbacks to update your app when images are ready.
Outcome: Your app goes live with image generation without managing multiple provider accounts or storage infrastructure, and you can iterate on model choice by changing the model name in one place.
You paste the llms.txt prompt into Claude, and the agent installs the HiAPI Skills. It then generates a video with Seedance 2.5 based on your prompt, storing the result persistently.
Outcome: Your agent can autonomously produce and store media assets via a standardized integration, reducing development time for agentic workflows.
You use the Playground to test Veo 3.1, Kling 3.0, and Seedance 2.5 side-by-side, comparing quality and cost per second before integrating the best one into your product.
Outcome: You make an informed model choice based on real outputs and pricing, and you can switch models later without rewriting your integration.

Models Under the Hood
as of 2026-08-19
Limitations
- HiAPI is a cloud-based API with no offline mode.
- Pricing is pay-per-use, with only a $1 trial credit (2,000 credits) for free.
- The model catalog is curated, not exhaustive, and some models only support specific task types (e.g., Seedance 2.5 supports text-to-video, image-to-video, and reference-to-video, but not all routes).
- Audio models are still limited in scope.
- You are dependent on HiAPI's gateway, so any outage or pricing change affects you directly.

Where the pricing makes sense
The company stage and team size where HiAPI's pricing actually pencils out — and where peers do it cheaper.
HiAPI's pay-as-you-go pricing fits startups and teams that need flexibility without long-term contracts. It's competitive with fal.ai and Replicate for per-generation costs, though you pay a premium for the convenience of a unified API and persistent storage. If you're a high-volume user, volume discounts can bring costs in line with direct provider APIs.
Setup time & first value
How long it actually takes to get something useful out of HiAPI — broken out by persona, not the marketing-page minute.
Developers can get a free API key and make their first image generation request within 15 minutes by following the quickstart and using the provided curl example. Setting up agent integration (MCP or Skills) takes about 30 minutes, as you need to configure the MCP client or install skills into your agent environment. Text API integration is similar, with the OpenAI-compatible endpoint working
Switching to or from HiAPI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From fal.ai: replace your fal client calls with HiAPI's /v1/tasks endpoint and use persistent storage for outputs.
- →From Replicate: map your model names to HiAPI's model list and switch predictions to the async task lifecycle with callbacks.
- →From multiple provider SDKs (e.g., OpenAI, Google, ElevenLabs): consolidate into one API key and one schema, reducing code complexity.
- ↗To direct provider APIs: if you outgrow HiAPI's curated catalog, you can switch to OpenAI, Google, or ByteDance directly, but you'll need to handle storage and callbacks yourself.
- ↗To fal.ai or Replicate: if you need more niche models or lower per-generation costs, these platforms offer similar task-based APIs.
- ↗To an OpenAI-compatible proxy: if you only need text models, you can point your existing OpenAI SDK at HiAPI's base URL and migrate later without breaking changes.
