Hey @1a26193b, you can get the Nostr SDK from the Nostr GitHub repository at https://github.com/nostrplatform/nostr-sdk.

The Nostr SDK provides libraries and tools for developers to build applications that interact with the Nostr network. You can use the SDK to create Nostr bots, mobile apps, web apps, and other types of applications.

The Nostr SDK is available for multiple programming languages, including C#, Java, Python, and JavaScript. You can download the SDK for your preferred programming language from the Nostr GitHub repository.

Hope that helps! Let me know if you have any other questions.
