Muse API v1

October 12, 2026

useapi.net is a third-party API, not affiliated with or endorsed by Meta.

The useapi.net Muse API is a REST API for the videos and images of Muse, Meta’s personal AI agent: one POST makes a 10-second video with sound and spoken dialogue from text, a photo or another video, or an image, on your own Muse account. Meta’s official Model API sells the Muse Image model at $0.01 per image, but as of October 2026 it has no video generation and no API for the Muse agent at muse.ai, where the videos are made. This experimental API drives the Muse agent instead. This first release covers image and video generation, and we will keep extending it to support more of what Muse can do.

What it makes

Output Endpoint Details
Image POST /jobs/image Text to image, or image to image from up to 9 reference images. WebP, about 2 to 2.5 megapixels.
Video POST /jobs/video Text to video, image to video or video to video, with sound and speech. MP4, about 10 seconds at 720p.
Uploads POST /assets Your images, videos and audio files as inputs, up to 50 MB each.
Downloads GET /assets/assetId Any uploaded or generated file.

Good to know

  • Aspect ratio is set in the prompt. Ask for any common ratio explicitly, for example in exactly 4:5 aspect ratio, and Muse follows it (we tested 1:1, 2:3, 3:4, 4:5, 9:16 and their landscape forms, and 21:9). Image to video keeps the start image’s shape unless the prompt asks for another ratio. There are no model, resolution or duration parameters.
  • Every video is about 10 seconds long. Lines of dialogue in quotes come out as speech.
  • Every generated file is an asset id that the next job takes as an input, so edits chain without downloads or re-uploads.

Usage limits

Muse meters each account weekly. GET /accounts/email returns the plan and usage in quota: tier, percentUsed, resetsAt and quotaStatus.

Plan Price Weekly allowance
Free $0 not published
Power $20/month 500 million Muse tokens
Maximum $100/month 3 billion Muse tokens

Source: Meta, About Muse subscriptions, October 2026. Availability can differ by region.

  • On the free plan, a video used 2 to 3 percent of the weekly allowance in our tests and an image 0 to 1 percent. Meta does not publish per-job token costs.
  • The allowance resets at resetsAt. Once it is used up, new jobs go to your other accounts, and a job pinned to the account answers 412.

Pricing

A flat $15/month covers every useapi.net API. Each subscription adds 3 Muse accounts, and generations run on their own Muse allowance, with no per-image or per-video charge from us.

Start using the API

A single $15/month subscription covers every API on useapi.net — one token, all services. You connect up to 3 of your own provider accounts per service, and useapi.net handles the REST API, load balancing, and polling.

Subscribe — $15/month

Pricing, crypto payment, and volume options — full refund within the first 14 days if you have fewer than 50 successful generations.

Questions

Does Meta Muse have an API?

Not for video. Meta’s official Model API sells the Muse Image model at $0.01 per image, but as of October 2026 it has no video generation and no API for the Muse agent at muse.ai, where the videos are made. The useapi.net Muse API runs the Muse agent on your own account: add the account with its email and password, then make videos with POST /jobs/video and images with POST /jobs/image.

Is there a Muse video API?

Not from Meta, as of October 2026. Through useapi.net, POST /jobs/video makes an MP4 of about 10 seconds at about 720p, with sound, from a prompt, a photo or another video. Write a line in quotes and it is spoken, so a single photo becomes a talking photo.

Is this Meta’s official API?

No. useapi.net is an independent, third-party API, not affiliated with or endorsed by Meta. It runs on a Muse account you own and add yourself.

Does the free Muse plan work?

Yes. In our tests on the free plan, a video used 2 to 3 percent of the weekly allowance and an image 0 to 1 percent, roughly 30 to 50 videos a week per account. See Usage limits for the paid Muse plans.

Where does Muse work?

  • Muse is available only in the US and Canada (Meta), so create the account there. Once it is added, you can call the API from anywhere.
  • Finish Muse’s onboarding at muse.ai, including Meta’s age check, and create one image there.
  • The account must have email + password sign-in, because the API signs in with the email and password. A Meta account that signs in only with an emailed code has no password yet: create one in Meta Accounts Center (Password and security), then add the account here. Without a password the add is refused with 400.
  • Use the account only for the API, with no other automation tools on it. Opening it at muse.ai in a browser is fine.

How much does it cost?

A flat $15/month to useapi.net, which covers 3 Muse accounts and every other useapi.net API. Generations use each account’s own Muse allowance, with no per-image or per-video charge from us.

Can my Muse account get banned?

It can happen, and we cannot promise that it won’t. Meta’s Muse terms count using the service in unauthorized, automated ways as a violation. Use a dedicated account for the API, with no other automation tools on it, as Setup Muse recommends. When Meta asks for a security check, the API pauses the account and emails you (see If the account needs attention). You use your account at your own risk, as our Terms of Service say.
