  title: Nuclia RAG-as-a-Service Ask Resources API
  description: Specification of the Nuclia (Progress Agentic RAG) cloud API. Nuclia turns unstructured data - documents, files, audio, video, web pages and conversations - into searchable, queryable Knowledge Boxes. This document covers the regional NucliaDB REST API (Knowledge Boxes, resources and ingestion, search, find, ask/chat RAG answers) and the Nuclia Understanding API (NUA / Predict) endpoints. All endpoints are served from a regional zone host.
