Authentication

Pricing Dashboard Image studio

Authentication model

Image and video API endpoints support API-key authentication. For external integrations, use an API key with the Authorization header.

Important: /api/register/ and /api/login/ are currently disabled and return 403. Use the web login flow and API key management instead.

Recommended setup

  1. Sign in at /accounts/login/.
  2. Create an API key in your dashboard, or via POST /api/api-keys/ while authenticated.
  3. Send requests to /api/v1/... with your key in Authorization.
  4. For model discovery, call /api/v1/models/image/ and /api/v1/models/video/.

Authorization header formats

The backend accepts multiple auth header formats. 

Authorization: Bearer YOUR_API_KEY
Authorization: Token YOUR_API_KEY
Authorization: YOUR_API_KEY

Create an API key (session-authenticated)

If you are logged in with a browser session, you can create keys programmatically. 

curl -X POST https://ulazai.com/api/api-keys/ \
  -H "Content-Type: application/json" \
  -H "X-CSRFToken: YOUR_CSRF_TOKEN" \
  -H "Cookie: sessionid=YOUR_SESSION" \
  -d '{
    "name": "Production key"
  }'

Response includes the full key once. Store it immediately.

Auth troubleshooting

  • 401 means the key is missing, invalid, or revoked.
  • 402 can indicate no purchased credits for API usage.
  • Welcome credits are website-only and cannot be used via API.
