Acelab Material Hub Platform API
The private production API behind the Acelab Material Hub web application and Revit add-in. It is not a published developer product: no OpenAPI, no API reference and no key-issuance flow is published anywhere on acelabusa.com, and "Custom API Integrations" are listed as an Enterprise-tier, sales-gated item on the pricing page. The base URL recorded here is the one Acelab's own Nuxt application at app.acelabusa.com calls at runtime; requests to it answer 401 with WWW-Authenticate: Bearer, and the ASP.NET Swagger surface at /swagger/v1/swagger.json answers 401 with WWW-Authenticate: Basic — the machine-readable contract exists but is behind an access control.
