  No first-party Pay1st / Carry1st client SDK was found on npm, PyPI, Maven Central, NuGet,
  pkg.go.dev, RubyGems, Packagist, or crates.io, nor referenced in the Pay1st documentation.
  The docs provide raw HMAC-SHA256 signature code samples (Bash/PHP/Java/C#/Python) for
  developers to integrate directly against the REST API rather than a packaged SDK. No SDKs
  pointer is wired because no official client library exists.
