Uncountable External API
The Uncountable External API is the authenticated REST surface of the Uncountable R&D platform. Its documented entry point is the list_entities endpoint, which returns rows from a Listing Configuration defined in the Uncountable UI rather than querying entities directly. It is protected by OAuth 2.0 (authorization code with PKCE) using the EXTERNAL_API_READ and EXTERNAL_API_WRITE scopes, or by basic authentication for legacy use, and enforces the same role-based permissions as the web application. Full endpoint and parameter reference is published behind the application sign-in at /docs.
