A request selects a dataset (e.g. GLBX.MDP3, XNAS.ITCH, DBEQ.BASIC), one or more symbols, a schema (MBO full order book, MBP-1, MBP-10, trades, OHLCV bars, statistics, definition, and more), and a time range, and receives normalized records in Databento Binary Encoding (DBN), CSV, or JSON. Endpoints are grouped as metadata (catalog discovery and cost estimation), timeseries (streaming data retrieval), symbology (symbol resolution), batch (asynchronous flat-file jobs), and reference (security master, corporate actions, adjustment factors). Requests authenticate with HTTP Basic auth using your Databento API key as the username and an empty password. Live market data is delivered separately over a raw TCP binary DBN protocol (with CRAM authentication) and is NOT part of this REST document.\n\nContact Support:\n Name: Databento", "schema":
