This file was generated by the API Evangelist enrichment pipeline from Ohmium's public website. method: generated. ## No public API Ohmium publishes **no public developer program**. As of 2026-08-04 there is no developer portal, no API reference, no SDK, no webhook catalog and no machine-readable specification (OpenAPI, AsyncAPI, GraphQL SDL, Postman collection) on any Ohmium host. Contract discovery probed `www.ohmium.com`, `ohmium.com` and every certificate-transparency-discovered subdomain for `/openapi.json`, `/swagger.json`, `/api-docs`, `/graphql`, `/llms.txt` and the full `/.well-known/*` set; every path returned 404 or an HTML single-page-app shell. The software surfaces that do exist on Ohmium subdomains are third-party SaaS products or login-gated internal applications, not an Ohmium API: - `canary.ohmium.com` — Axiom, a third-party operational historian by Canary Labs (the RM&M monitoring view). Vendor product, not an Ohmium API. - `workspace.ohmium.com` — Freshworks, hosted on an Ohmium custom domain. - `help.ohmium.com` — Ohmium Service Desk (Freshdesk). - `leadtime.ohmium.com` — "Ohmium · Lead Time Guide", an Azure Static Web App whose `/api/*` routes return `401 Unauthorized` (Azure Static Web Apps auth).
