Rankings data is available through an open API, and we partnered early on with ESPN Rise to feature football rankings on their site. Check out the bottom right-hand corner of http://espn.go.com/high-school-sports/rise/football/ where they build a widget consuming the Rankings API. The API is now available for all developers to leverage in their applications or websites.
Determine the geographic context for ranking data by querying the Playoff Group, Playoff Subgroups or Sportspower School Size Classification API for the relevant group ID (i.e. "60" for all very large highschools in the United States).
Use the geographic context (group ID) to get a list of rankings for a given sport.
During the initial rollout, only highschool football (api.sportspower.com/football/) and basketball (api.sportspower.com/basketball/) is supported with lacrosse data from laxpower.com soon to follow.
