  label: DNV Class Status API
  description: DNV's Class Status API provides programmatic access to vessel classification data. Authentication uses OAuth
    2.0 with Azure AD B2C as the identity provider. Access tokens are obtained from the Microsoft identity platform and are
    valid for approximately 20 minutes. Access requires a separate API contract with DNV. The API supports retry logic using
    exponential backoff for resilience.
