Ask natural language questions about blockchain data using Hubble's RAG (Retrieval-Augmented Generation) knowledge base. The endpoint processes queries against a V2 knowledge base with configurable confidence thresholds and data sources, returning structured results with verification status. Powered by Hubble RPC's Lego API. | Input: Accepts a natural language question about blockchain data, optional data source selection (FILE or SINGLE), and confidence threshold for filtering results. | Output: Returns an array of query results, success status, ISO 8601 timestamp, and gateway metadata including payment verification and router information. | Use cases: I want to ask questions about blockchain data in natural language; Query the Hubble knowledge base for blockchain information; Get verified blockchain data answers with confidence scoring; I need to retrieve blockchain information using semantic search
