To use the Zinc API, you must authenticate every request with your API key.
You can find your API key in your Zinc dashboard after creating an account.

​
Example Authentication Request

Authentication is performed using Bearer token authentication.
  • Include your API key in the Authorization header
  • Format: Authorization: Bearer <your_api_key>
Never share your API key or expose it in public repositories, client-side code, or other insecure locations. Your API key is tied to your account, and you are responsible for all requests made with it.
If you believe your API key has been compromised, please contact support@zinc.com immediately.
