Help me integrate the official KmerHosting SDK. First identify my application's language and choose the official TypeScript, Python, PHP, or Java SDK. Keep KMERHOSTING_API_KEY server-side or in a secret manager, never hard-code or expose it in client code. Use idempotency for supported writes and follow the official resource model. Official documentation: https://kmerhosting.com/docs/developer/sdk . API-key guide: https://kmerhosting.com/docs/developer/api-keys . Official GitHub repository: https://github.com/KmerHosting/sdk . Give me the exact install command and minimal working code for my stack, then explain which scopes the API key needs.
