​
Finding your API key

Your API key is available in the Catalyst dashboard under project settings.

​
How authentication works

Use the same API key across:
  • Inference API — calling models (both off-the-shelf and custom deployments)
  • Catalyst platform — SDK and CLI operations
  • Observability — routing traffic through the gateway
Pass the key as a Bearer token in the Authorization header, or use the api_key parameter in the OpenAI SDK.

​
Best practices

  • Keep API keys out of source control
  • Rotate keys periodically
  • Use environment variables to store keys in your application
