Creating API Keys

To create an API key:
  1. Navigate to krea.ai/settings/api-tokens
  2. Make sure you’re in the correct workspace (using the workspace toggle on the top left)
  3. Click “New Token”
  4. Give your token a descriptive name
  5. Save the token securely—you’ll only see it once!
Security Guidelines
  • Store tokens in environment variables, never in code
  • Use different tokens for development and production
  • Revoke tokens immediately if compromised
  • Never commit tokens to version control
  • Never share tokens publicly

​
Using API Keys

Include your token in the Authorization header of all requests: 
curl -X POST https://api.krea.ai/generate/image/bfl/flux-1-dev \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "a serene mountain landscape at sunset",
    "width": 1024,
    "height": 576
  }'

​
Billing

API usage consumes your workspace’s compute units—the same pool used by the Krea web app.
Failed and cancelled jobs do not consume compute units. You’re only billed for completed jobs.

​
Compute Costs

Different models consume different amounts of compute units: Image Models:
ModelCompute UnitsEstimated Time
Flux~5~4 seconds
Seedream 4~24~20 seconds
ChatGPT Image~183~60 seconds
Video Models:
