⚠️ Never embed your API key in client-side apps (mobile, browser JS). Call the API from your server.
The v2 SDK ships as IDAnalyzerV2 (the legacy IDAnalyzer package id remains the API v1 SDK):
dotnet add package IDAnalyzerV2Targets .NET Standard 2.1 (works with .NET Core 3.x, .NET 5/6/8+).
Pass your API key to each client, or set the IDANALYZER_KEY environment variable. The SDK targets the US endpoint (https://api2.idanalyzer.com) by default; set IDANALYZER_REGION=eu for the EU endpoint (https://api2-eu.idanalyzer.com). An unrecognized region throws InvalidArgumentException.
