This is the setup guide for Muse API. A Muse account and a useapi.net subscription are required for the API to work.

Add a Muse account with its email and password. The API signs in once and keeps the account signed in from then on.

Before you start

  • 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.

Add the account

A new account answers 201, a re-added one 200, with health: "OK", sessionExpiresAt and quota. Each account runs 2 jobs at a time unless you set maxJobs (1 to 5) above. To change it later, post the email with a new maxJobs and no password to POST /accounts.

What to expect

  • The API renews the session itself: before the 30-day session expires, and whenever Muse asks for a new sign-in. You never re-add the account for that.
  • Muse emails the account a login code on each sign-in. Nothing needs to be done with it.
  • Re-adding the account with the same password reuses its live session, so it does not sign in again.

If the account needs attention

The API pauses an account it cannot use, emails you once, and answers 596 with the reason, also shown in health on GET /accounts:

  • Meta asks for a security check, usually after a sign-in from a new place. Sign in at muse.ai in a browser, complete the check, then add the account again with the same email and password.
  • Muse refused to sign in when the session was renewed, usually because the password changed. Add the account again with the current password.

Temporary problems never pause an account. They answer 503, and a retry works.

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

  • 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.
