 * Data Points

 * Data points are available per symbol and return individual plain text values. Retrieving individual data points is useful for Excel and Google Sheet users, and applications where a single, lightweight value is needed. We also provide update times for some endpoints which allow you to call an endpoint only once it has new data.
