RWJL.NET API

This section of the site provides fellow researchers access to the data collected.
Along with the human readable website; the site provides machine readable data.

Specifically, the API provides access to the data in "Comma Seperated Value" (.CSV) format.
The API allows access to all the data or a subset of the data.

Data is accessed by HTTP request to the /api/export_fights/start/finish" path on this site.
A list of final fight numbers by event is accessed via "/api/fights".
