Authentication

Create a key

1. Sign in to the Developer page.
2. An active paid subscription is required for key creation and video generation.
3. Create a key, copy it when shown and save it in your server’s secret storage.
4. Send it in the Authorization header.

Authorization: Bearer $JEMSU_API_KEY

Keys begin with jem_live_. The account can have up to 10 keys. A key reads only its owner’s jobs, saved styles and credit balance.

Check the connection

curl --fail-with-body https://app.jemsu.ai/api/v1/credits \
  -H "Authorization: Bearer $JEMSU_API_KEY"

Rotate or revoke

Create a replacement key, update the server environment, confirm a credit-balance request works, then revoke the old key on the Developer page. If a key is exposed, revoke it promptly.
