  detail: Every developer host is NXDOMAIN on both willowwealth.com and the legacy yieldstreet.com (api., developer., docs.,
    dev.), the yieldstreet GitHub org's 14 public repos are internal Scala/Akka and React Native forks with no client library,
    and no package exists on npm, PyPI or RubyGems - the private-markets platform is sold as an end-user web and mobile product
    only.
