Metered pricing
Databento only charges for the data that you use. You can find rates (per GB) for the various datasets and estimate pricing on our Data catalog. We meter the data by its uncompressed size in binary encoding.
When you stream the data, you are billed incrementally for each outbound byte of data sent from our historical gateway. If your connection is interrupted while streaming our data and our historical gateway detects connection timeout over 5 seconds, it will immediately stop sending data and you will not be billed for the remainder of your request.
Duplicate streaming requests will incur repeated charges. If you intend to access the same data multiple times, we recommend using our batch download feature. When you make a batch download request, you are only billed once for the request and, subsequently, you can download the data from the Download center multiple times over 30 days for no additional charge.
You will only be billed for usage of time series data. Access to metadata, symbology, and account management is free. The Historical.metadata.get_cost method can be used to determine cost before you request any data.
