How is the Muapi Sandbox API priced?

Per-second usage billed from your Muapi credit balance while a sandbox is running: $0.036/hour for small (2 vCPU, 4 GB), $0.072/hour for default (4 vCPU, 8 GB) and $0.144/hour for large (8 vCPU, 16 GB). Stopped sandboxes are free. There is no subscription and no minimum beyond a $1 balance to start.

Does it use the same API key as image and video generation?

Yes. One Muapi API key and one credit balance cover sandboxes and 500+ image, video and audio models, so an agent can run code and generate media without a second vendor.

FAQ

What is a sandbox API?

A sandbox API lets your code or AI agent create an isolated cloud Linux machine on demand, run shell commands, read and write files, then stop or delete it, all over REST.

How is it priced?

Billed per second from your Muapi credits while running: $0.036/hour (small), $0.072/hour (default) or $0.144/hour (large). Stopped sandboxes are free. You need a $1 balance to start.

Same key as image and video generation?

Yes. One key and one credit balance cover sandboxes and 500+ image, video and audio models.

What happens when credits run out or the sandbox is idle?

It is stopped automatically when your balance cannot cover usage or after 15 minutes without activity. A stopped sandbox's files are kept for 14 days.
