How it works
A schedule is worth what its sources are worth, and how honest it is about what it doesn't know. This is the second part: where every piece of data comes from, how often it updates, what we leave out and who to write to if something is wrong.
Where the data comes from
- Boxing Data API
- Fight nights with real start times, broadcasters by country and full cards. Its free tier only reaches a few days ahead.
- Wikipedia
- The big fights with records and nicknames, and the table of current champions by division and sanctioning body.
- TheSportsDB
- A daily sweep of the calendar six months out: it reaches fight nights the other two miss, but with no time or broadcaster.
The schedule is downloaded, normalised and validated once a day. The most complete source always wins: whoever gets there first keeps the fight and the others only fill in what nobody had. If a source fails or returns odd data, nothing is written and the last good schedule is kept: yesterday's schedule beats a broken one. Past fight nights are archived in past fights.
What is completed by hand
The supporting sources publish neither time nor broadcaster, and the main source's free tier doesn't reach distant fights. For the big ones, the ones people actually search for, we fill in what is missing by hand: start time, broadcasters by country, title at stake. Every patch cites its source and review date, and as soon as the API reaches the fight, its data takes over.
What we don't publish
- A result that isn't on Wikipedia. None of the three schedule sources publishes who won; the result is taken from the fight's Wikipedia article when it exists and records it, and we say where it comes from. If it isn't there, the fight stays without a result rather than making one up.
- The promoter of each fight night, for the same reason.
- A start time that isn't confirmed. Where we don't know it, we say so; it isn't padded with midnight.
- Platform prices. They change every few months and a stale figure misleads more than none. The where-to-watch guides describe the model: subscription, pay-per-view or free-to-air.
- Promotional posters, which belong to the promoters and would need a licence we don't have.
Times
Everything is published in Spain time and the browser converts it to the visitor's zone. Each fight page also spells out the time for both US coasts, Mexico, Colombia and Argentina. The time is the start of the card, not the main event, which walks two or three hours later. And you can take the whole schedule to your calendar: agenda.ics.
