        "ou_even": 5,
        "wl_accuracy": 62.79,
        "spread_accuracy": 49.61
    }

Date ranges for included games can be altered using the startDate and endDate query parameters such as:

A Player in an Event Comparisons#

This example retrieves the Player's Performance Prediction Comparison Report for a given event.

/{sport}/v2/reports/players/{player_uuid}/events/{event_uuid}/comparisons

The result contains a json object listing each predicted prop along with the actual result from the box score and in some cases the average market over/under when available. The actual comparison values will vary by player positions.

Here's an example of the comparisons in the response attributes for a Quarterback:
