Authentication

Fizzly API uses Bearer Token authentication, fully compatible with OpenAI API.

Bearer Token Authentication

Add the Authorization header to your requests:

Authorization: Bearer your-api-key

Example Request

curl https://api.fizzly.com/v1/chat/completions \
  -H "Authorization: Bearer sk-xxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-4o",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

API Key Types

Type	Prefix	Permissions
Standard Key	`sk-`	Full API access
Restricted Key	`rk-`	Custom permission scope
