  proton exchange membrane (PEM) electrolyzer systems for cost-competitive green hydrogen
  production. Its Lotus PEM electrolyzer platform integrates power electronics, water treatment
  and controls into skid-mounted modules for industrial, energy and mobility customers, and is
  paired with EPC and remote monitoring and maintenance (RM&M) services. Ohmium is a hardware
  and clean-energy engineering company: it publishes no public developer program, no API
  reference and no machine-readable specification, and its customer-facing monitoring and
  service portals are third-party SaaS products hosted on Ohmium subdomains behind login.'

  detail: Ohmium manufactures PEM electrolyzer hardware and publishes no developer
    program at all; the only software on its domains is third-party SaaS on custom
    subdomains (Canary Labs Axiom at canary.ohmium.com, Freshworks at workspace.ohmium.com,
    Freshdesk at help.ohmium.com) plus an Azure Static Web App lead-time tool whose
    /api/* routes answer 401.
