Almost all Unprice API endpoints require authentication using an Api key. Api keys provide access to your Unprice resources.

​
Bearer Authentication

Authentication is performed using HTTP Bearer authentication in the Authorization header: 
Authorization: Bearer unprice_live_1234567890
Example request: 
curl -X GET "https://api.unprice.dev/v1/plans/getPlanVersion/{planVersionId}" \
  -H "Authorization: Bearer unprice_live_1234567890" \
  -H "Content-Type: application/json"

​
Security Best Practices

Never expose your api key in client-side code or include it in public repositories. For frontend applications, always use a backend server to proxy requests to the Unprice API.

​
Authentication Errors

If your authentication fails, you’ll receive a 401 Unauthorized or 403 Forbidden response with an error message: 
{
  "meta": {
    "requestId": "req_abc123xyz789"
  },
  "error": {
    "title": "Unauthorized",
    "detail": "The provided api key is invalid or has been revoked",
    "status": 401,
    "type": "https://unprice.dev/docs/errors/unauthorized"
  }
}
Common authentication issues include:
  • Missing the Authorization header
  • Invalid key format
  • Revoked or expired api key
