Why we're up-front about a 5-minute live-data lag

Every other paid sports API in our price range hedges or fudges its live-data SLA. We chose not to. Here's the reasoning, and what we actually do.

The hierarchy of sports data

Football data is a tiered market:

We're tier 3 during live matches and tier 4 once they're over. That's a real position in the market — there are uses cases where it's a great fit and uses cases where it's not.

What we actually do during a live match

Three concurrent sources:

  1. Wikipedia match-page scraper, polled every 60s from our cron. Wikipedia editors update WC matches within a minute or two — surprisingly reliable during the actual tournament.
  2. FIFA match center scraper, polled every 60s as a cross-check.
  3. Manual operator override — an admin UI where we can fix a score / goalscorer / red card if our scrapers disagree with what we're seeing on the broadcast.

Result: typical lag during a live match is 2–5 minutes. We say "5 minutes" on the marketing page so customers plan around the worst case.

Why not just buy a feed?

API-Football's $99/mo tier would give us sub-minute updates. Why not pay them and pass the cost through?

Math: $99/mo of cost across our planned ~80-customer peak = $1.25/customer of margin lost. That's tight at our $9 / $29 / $99 tiers. We'd have to push to higher prices or much higher volume to break even, and at that point we're competing with API-Football directly.

Better play: serve the customers who don't need real-time, are happy with 5-min lag, and would otherwise pay nothing because Sportradar pricing locks them out of the market entirely.

The honesty calculation

We could write "real-time live data" on the homepage and most customers wouldn't notice the lag for the first few weeks. By tournament end we'd have:

Versus being honest up front:

The math is obvious if you're optimizing for "run this for 5 years." The only people honesty hurts are the ones optimizing for "exit in 18 months."

What we'll improve

Phase 2 plans:

None of those make us tier 1. They make us a really good tier 3.
