Pre-Game Event Predictions#

In the following example you will retrieve the upcoming event predictions for the next NFL game.

Related Sports Data APIS

Method	Description	Availability
`GET`	`/{sport}/v2/events`	All Leagues
`GET`	`/{sport}/v2/win_losses`	All Leagues

Start By querying the /{sport}/v2/events endpoint for the next available game in the NFL. Filter by league.uuid, startDate and order:

GET https://api.quarter4.io/american-football/v2/events?startDate[after]=now&order[startDate]=asc&league.uuid=38344248-9889-11eb-a8ab-0647cdb505d0&page=1&count=1

This result contains a list of upcoming events (here limited to 1 due to the count query parameter). For example:
