Databento Metadata API

Discovery and cost-estimation endpoints for the historical catalog. List publishers, datasets, schemas, and fields; look up per-dataset date ranges and data-quality conditions; and pre-compute the record count, billable size, and dollar cost of a query before you run it. Essential for planning research and controlling spend on financial and reference data.
