The OpenRouter Video Generation API puts Seedance, Veo, Wan and other video models behind one asynchronous endpoint: according to OpenRouter's code-first guide published on 25 August 2026, you submit a prompt to a single videos endpoint, get a job ID back immediately, poll until the status reaches completed, then download the finished MP4 — and switching between video models is a one-line change to the model field. If you have ever tried to support two video providers in one product, each with its own endpoint, job statuses, polling logic and output format, you already understand exactly why this exists.

AI video is where AI images were eighteen months ago — moving from party trick to production line — and I use generated video across my own content operation. The painful part has never been the models; it is the plumbing. OpenRouter already solved that plumbing problem for text models, and this guide extends the same trick to video. Here is what the official guide actually describes, why the API is asynchronous, and the production lessons in it that most people will learn the expensive way.
How the OpenRouter Video Generation API Works
Per the official guide, the workflow has four steps. You submit a generation request to the videos endpoint and receive a job ID immediately, rather than waiting on an open connection. You poll the job's status endpoint on an interval — the guide suggests roughly thirty seconds is reasonable — until it reaches a terminal state: completed, failed, cancelled or expired. You then retrieve and save the finished video. And when you want a different model, you change the model identifier and keep the same endpoint, auth, polling loop and download logic.
The guide is candid about the one wrinkle: model-specific settings such as duration and aspect ratio still need adjusting per model. Its answer is a models discovery endpoint — you can query the video models catalogue to see each model's supported durations, resolutions, aspect ratios, frame-image support, audio capabilities, pricing information and provider-specific parameters, which the guide notes is more reliable than assuming settings that one model accepts will work on another. Provider-specific parameters pass through in a dedicated options object, so the abstraction does not lock you out of each model's special features.
Why an Async API Is the Right Design for Video
The guide's reasoning here is worth internalising because it applies to every long-running AI job you will ever build. Video generation takes anywhere from several seconds to a few minutes — a model has to generate many frames, keep them visually consistent, and sometimes produce matching audio. Keeping one HTTP request open that whole time is fragile: browser sessions close, serverless functions hit execution limits, proxies time out. Separating submission from completion means your application keeps running while the model works, and — the underrated part — a job can be recovered after a restart because generation is attached to a persistent job ID rather than a long-lived connection.
Getting started requires almost nothing: per the guide, you need an OpenRouter API key and anything that can send HTTP requests, with worked examples in Python and TypeScript. The guide stores the key in an environment variable and authenticates with a bearer token — standard practice, spelled out properly for once.

The Production Notes Everyone Will Wish They Had Read
The strongest section of the guide is the pre-production checklist, and two lessons stand out. First, cost: video pricing varies by model and configuration — duration, resolution, audio and the provider's billing method all move the number — so the guide says not to hard-code one universal cost formula. Instead, query the models endpoint and read the selected model's pricing information before estimating or submitting a big batch, then compare estimates against the actual cost that completed jobs report back in their usage data. That feedback loop catches the silent budget-killers: a higher resolution here, generated audio there.
Second, duplicate jobs: the guide draws a sharp line between a failed polling request and a failed generation job. Your app can lose its connection while checking status even though the provider is still happily rendering — resubmit immediately and you may end up with two videos and two charges for one user request. The fix, per the guide, is persisting the job ID as soon as submission succeeds and tracking attempts against your own internal request record. It even sketches the fields a sensible job record carries. This is the difference between a demo and a system, and it is the part I would make any team member read before touching the API.
Where This Fits an AI Content Business
My interest here is not academic — video is the most expensive content format to produce traditionally and the fastest-compounding one to automate. One endpoint over Seedance, Veo and Wan means you can A-B test video models on the same brief without rebuilding integrations, route cheap drafts to one model and hero shots to another, and swap models when the leaderboard shifts — the same model-routing discipline I apply to everything in the Agent OS, the agent operating system I built and test daily in my own business. It also pairs naturally with agent workflows: I have covered AI video generation with Hermes Agent and the Hermes plus Higgsfield combination before, and an async job-ID API is exactly the shape of tool an agent can drive unattended — submit, persist the ID, check back, deliver.
On evaluation: models change fast enough that I re-run my own tests on Goldie Bench, my personal benchmark, whenever the stack shifts, and my advice for video is the same — run your own brief through the candidates before you standardise. If you are already deep in the OpenRouter ecosystem, this slots alongside what I wrote about the OpenRouter Fusion API — that page covers OpenRouter's model-routing layer for text, while this one covers the dedicated asynchronous video endpoint — and my guide to using OpenRouter with Hermes Agent covers wiring the account side into an agent. For the fully-automated end of the pipeline, my Hermes AI video generator build shows what the finished machine looks like.
OpenRouter Video Generation API: Quick Reference

OpenRouter Video Generation API FAQs
Does OpenRouter support video generation?
Yes. Per the official guide published on 25 August 2026, OpenRouter offers a dedicated asynchronous video API: submit a prompt to the videos endpoint, poll the job until it completes, and download the result — with Seedance, Veo, Wan and other models behind the same interface.
How do I generate a video from text with the OpenRouter Video Generation API?
Send a request with a model and a prompt to the videos endpoint. You get a job ID and a polling URL rather than the video itself; poll until the status is completed, then download the finished file.
Can I switch video models without rewriting code?
Yes — the request shape, authentication and polling loop are identical across models, so only the model field changes. Model-specific parameters still reach the provider through a pass-through options object.
Is it cheaper to generate AI video locally or through the API?
The guide frames it honestly: local generation has no per-clip fee but real upfront hardware and maintenance costs, while the hosted API keeps cost variable and tied to usage. Which wins depends on your volume and whether you already own the hardware.
Which video models does the OpenRouter Video Generation API support?
The catalogue includes Seedance, Veo, Wan and others, and it grows — the guide recommends querying the video models endpoint for the current list along with each model's supported settings rather than relying on a static list.
Verdict: The Plumbing Finally Caught Up
The OpenRouter Video Generation API is infrastructure news, and infrastructure is where automation profits actually come from. Nothing about it generates prettier video — what it does is make video generation swappable, recoverable and billable in a way you can build a business process on: one integration, every major model, job IDs that survive restarts, and pricing you can query instead of guess. If AI video is anywhere on your roadmap, read the official guide, wire up the four-step loop, and put the model choice where it belongs — in a config field, not in your architecture.
