Authentication

API Key Authentication

All Nonce Private API requests require authentication using an API key passed in the request header.

You can authenticate using either of the following header formats: Option 1: x-api-key header

curl -X GET "https://api.nonce.app/private-api/v1/{workspace_id}/farms" \
  -H "x-api-key: your_api_key_here"

Option 2: Authorization Bearer header

curl -X GET "https://api.nonce.app/private-api/v1/{workspace_id}/farms" \
  -H "Authorization: Bearer your_api_key_here"

Both formats are supported and functionally equivalent. Choose the one that best fits your application’s architecture.

API keys are currently available by contacting the Nonce platform administrator. Please reach out to [email protected] to request access.
