The established service provides free, unrestricted access to raw data for customers for its financial market information. The same publish/subscribe and request/response interactions available via its proprietary interface can be accessed via API. This functionality gives access to data on current market trades, either real-time or delayed, along with reference data on reference data, historical information, and records of intraday trading.
API methods support selection by security using standard ticker symbols and the provider's own "Open Symbology" across classes of securities. Effective dates and date ranges may also be specified to retrieve historical results. Sources of pricing data are designated.
