Keys Usage Billing

API keys

Connect ComfyUI or your application to mvntSTUDIO without exposing your app session.

How do I use my API key? Quickstart

Set your API key as an environment variable before starting ComfyUI:

export MVNT_API_KEY=mvnt_live_xxxxxxxxxxxx

Or paste it directly into the api_key field on any MVNT node. /v1 requests use Authorization: Bearer <mvnt_live_...>, not your app JWT.

How do credits and revoked keys work?

Keys prefixed mvnt_live_ hit production. Local and test environments may issue mvnt_test_ keys. Credits are charged to the MVNT user wallet that issued the key, not to the key itself. If credits are insufficient, ComfyUI requests can fail. After revoke, ComfyUI requests using that key can fail immediately.
