  description: semantha's standardized RESTful web service for semantic processing of text documents and structured data extraction.
    Resources are organized under /api (info, domains/{domain}/referencedocuments, settings, roles, currentuser) and are consumed
    out-of-the-box or via the first-party Python SDK. The service is stateless per request (processed documents are not persisted)
    and enforces HTTPS. The production API base is a per-tenant semantha server URL of the form https://<tenant>/tt-platform-server/api.
