Authentication

OpenGateway inference APIs use API keys for authentication. The public /v1/models catalog is the exception and requires no API key.

Get your API key

Go to Dashboard

Add to request header

Include your API key in the Authorization header of every inference request.

Authorization: Bearer YOUR_API_KEY

Keep it secure

•Never expose your API key in client-side code
•Use environment variables to store your API key
•Rotate your API keys periodically
•If compromised, disable the key immediately from Dashboard

Example Request

curl https://apis.opengateway.ai/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "openai/gpt-4o-mini",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'
