Hello @shalva97 ! Thank you for raising the issue, I'm investigating and I'll keep you posted ⌛

After investigating with your player profile, the difference comes from two things.

1. The API includes all gamemodes by default

The Blizzard website shows Quick Play stats by default in the GAME section (3 659 games). The OverFast API, when called without a ?gamemode= filter, aggregates both Quick Play and Competitive — in your case, 11 additional competitive games are included, which accounts for most of the gap.

To match what the website shows, use ?gamemode=quickplay.

2. Blizzard's "ALL HEROES" total doesn't always match the sum of individual heroes

Even within Quick Play, Blizzard's own "ALL HEROES" aggregate (3 659) is 2 games higher than the sum of all individual hero stats (3 657). Those 2 games have no matching hero entry — likely games played on a beta/unreleased hero or another edge case on Blizzard's side. Since the API builds general stats by aggregating hero by hero, those 2 games are lost in the process. This is a Blizzard data quirk we can't easily work around.

The games_won drift follows the same logic, with an extra small rounding effect from how wins are derived when Blizzard's own win/loss numbers are internally inconsistent for some heroes.

@shalva97 Do you need help on anything else ?

?gamemode=quickplay seemed to fix. Anyway for my small project that small diff will be okay.
