  detail: JSW One is a B2B materials marketplace with no developer program of any kind - the api., developer., docs. and apis.
    subdomains of jswonemsme.com do not resolve in DNS, /openapi.json, /swagger.json, /graphql, /api-docs and every /.well-known/
    path return a hard 404 on www.jswonemsme.com and www.jswonehomes.com, the 830-URL sitemap contains no developer or reference
    section, and the company's own GitHub org (github.com/JSWOne, 10 public repos) ships CI actions and internal automation
    but no SDK, spec or client library.
