Public API Key for Client-Side License Activation and Validation

I want a public API key (separate from the secret x-api-key) that can be safely embedded in client-side Java applications to activate and validate licenses without requiring a backend server. This is important because I want to keep my project low-code/no-code without setting up backend servers or serverless functions. Currently, the x-api-key must be kept secret, which forces me to build a server-side proxy just for license operations. A public API key would: - Allow safe embedding in client applications (desktop Java apps, mobile apps, etc.) - Only have permission to activate and validate licenses (read-only operations) - Not expose sensitive account data or payment information - Enable developers to build simple applications without backend infrastructure This would make Creem's licensing system much more accessible for indie developers and small projects that don't need complex server architectures.
