HiAPI
One API key for image, video, audio, and text generation — with durable artifact links on every task.
HiAPI is worth a look when your problem is integration sprawl, not model choice. The task lifecycle — one POST, optional callback, persistent artifact links — is the actual product, and the agent surface (Remote MCP, Skills, llms.txt) is more developed than most API gateways bother with. The catch is a curated catalog: if the model you want isn't listed, no amount of clean plumbing helps. Price it per task before you commit, because the cheap headline rates only hold if you route carefully.

About HiAPI
HiAPI is a unified generative-media API gateway. You call leading image, video, audio, and text models through one async endpoint — POST to https://api.hiapi.ai/v1/tasks with a base model name and model-specific input, get a task ID, then poll or wait for a callback. Set storage to persistent and the response comes back with durable artifact links, so you skip building a storage layer per provider. Idempotency keys keep retries from creating duplicate jobs. The catalog is curated rather than exhaustive. Image models include GPT Image 2.5 Flare and Sunburst (from $0.050/image), GPT Image 2 ($0.030), Nano Banana 2 ($0.036), Seedream 5.0 Pro, Qwen Image 2.0 Pro, and FLUX 1.1 Pro. Video covers Seedance 2.5 (from $0.231/s, clips up to 30 seconds with synchronized audio), FLUX.3 Video ($0.090/s, storyboards and continuation), Seedance 2.0, Veo 3.1 ($0.290/s), Kling 3.0, Wan 2.7, and Grok Imagine 1.5 ($0.015/s). Audio includes MiniMax Music 2.6 (from $0.210/song) and ElevenLabs v3 ($0.125/1K chars, multi-speaker dialogue across 70+ languages). A lyria-3.5 song-generation endpoint was documented in September 2026. Text runs through an OpenAI-compatible surface via Chat Completions and /v1/responses. Agents get first-class treatment: a Remote MCP server, Agent Skills for Claude, Cursor, and Codex, and an llms.txt index you can paste into a coding agent so it can pick between Skills, MCP, or the raw API. It fits developers and platform teams shipping generative media into production who would rather buy one integration than maintain five provider SDKs. It does not fit people who want a GUI generator, teams that need self-hosted models, or anyone expecting a permanent free tier — a free key grants 200 credits.
Behind the Verdict
Pick HiAPI when you are already shipping image, video, or audio generation and the maintenance cost of five provider SDKs has become the bottleneck. The async task API is the reason to be here: submit a job, get a task ID, take a callback when it finalizes, and receive a durable link instead of running your own S3 pipeline. Idempotency keys matter more than they sound — retries on flaky networks are the most common way teams accidentally double-bill themselves. In practice, the cost math rewards attention. Grok Imagine 1.5 at $0.015/s and GPT Image 2 at $0.030/image sit far below Veo 3.1 at $0.290/s, so the route field and per-model pricing page are worth reading before you wire anything into production traffic. HiAPI's pricing page lists live rates per model with an image cost calculator; use it to size a launch rather than discovering the number on your first invoice. Where it bites: the catalog is deliberately narrow. If your roadmap depends on a model outside the listed set, HiAPI is the wrong middle layer — you will end up keeping the direct integration anyway, which defeats the point. Non-developers will find nothing to click; this is API-first with a Playground for parameter testing, not a creative tool. Against alternatives: fal.ai and Replicate go broader on model count and let you push more of the stack in-house, while a single-provider direct integration stays cheaper if you only ever need one model family. HiAPI's angle is the breadth-to-effort ratio plus the agent plumbing — Remote MCP, Agent Skills, and an llms.txt index that lets Claude, Cursor, or Codex discover and call models without a human writing glue code. We'd reach for it on a team where one or two engineers own generative media as an internal platform for other product teams. Callbacks plus

Real-world workflow fit
Concrete scenarios for the personas HiAPI actually fits — and what changes day-one when you adopt it.
You POST to /v1/tasks with model gpt-image-2.5-flare/text-to-image, storage set to persistent, and a callback URL, then render the returned durable link straight into your app's UI.
Outcome: A working image-generation feature with no S3 bucket, no signed-URL service, and no polling loop to maintain.
You paste the HiAPI llms.txt prompt into Claude or Cursor, connect the Remote MCP server, and let the agent call generate_text and get_task_status instead of you writing provider adapters.
Outcome: The agent discovers available models on its own and generates plus stores media inside a conversation, cutting integration work to a prompt.
You submit a Seedance 2.5 job with reference images and synchronized audio, register a callback, and store outputs persistently while users wait.
Outcome: Clips up to 30 seconds come back with durable links you can serve immediately, and the callback removes status polling from your backend.

Models Under the Hood
as of 2026-09-26
Limitations
- HiAPI is a cloud gateway: you call their hosted REST API only, so you depend on their uptime and on upstream providers staying reachable.
- Pricing is strictly pay-per-use credits with a free sign-up grant and no self-hosted option.
- The catalog is curated — models not listed in the docs (or not routed for your task type) are unreachable, and coverage differs by modality, with audio options narrower than image and video.
- Because HiAPI sits between you and the model providers, its per-model rates and route availability are what you buy.

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.
For a developer, first value lands in roughly 15 to 30 minutes: sign up, grab a free API key, test parameters in a model Playground, then POST your first task to /v1/tasks and read the returned link. Wiring callbacks and persistent storage is an afternoon. For an agent-driven setup, pasting the llms.txt prompt into Claude, Cursor, or Codex takes minutes, and Remote MCP handles model selection and
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 direct OpenAI API: move text calls to the OpenAI-compatible Chat Completions or /v1/responses endpoint and reuse your existing request shapes
- →From direct Replicate or fal.ai: replace per-provider prediction polling with POST /v1/tasks plus callbacks, and set storage to persistent to drop your own bucket
- →From a self-managed multi-provider adapter: collapse per-vendor SDKs into one model-and-input schema with shared idempotency keys
- →From ElevenLabs direct: route text-to-dialogue through the elevenlabs/text-to-dialogue model while keeping the same per-character billing basis
- ↗To direct provider APIs: if you settle on a single model, call that vendor directly to skip the gateway markup
- ↗To Replicate or fal.ai: move to a platform with more permissive custom model hosting if the curated catalog becomes limiting
- ↗To self-hosted inference: if on-prem becomes a hard requirement, replatform onto your own GPU serving stack and rebuild storage and callbacks
