Aggrometer — the gaming attention graph

Live cross-platform gaming market data for humans and AI agents. Aggrometer continuously measures ~2,000 games: Steam concurrent players (hourly) and Twitch live viewership (15-min, game-level aggregates), plus prices, discounts, top-seller ranks, clip velocity, review counts, and pre-release hype — joined per game.

Signature metric: aggro = live viewers ÷ concurrent players, same hour. Above 1.0, a game holds more audience than players — the signal that streamer marketing converts, that a spectacle moment is happening, or that attention is arriving ahead of sales.

REST API

Same key, plain JSON:

curl -H "Authorization: Bearer YOUR_KEY" "https://aggrometer.com/v1/boards/aggro?genre=RPG"

Who uses this

  • Game developers & publishers — genre whitespace, launch scouting, competitor attention
  • Marketing teams — watched-vs-played balance, per game and genre
  • Analysts & press — attention momentum, hype pipelines, discount effects
  • AI agents — all of the above, autonomously

Data notes

Game-level derived aggregates and estimates only. History accrues continuously since 2026-08-26; sparse series indicate a young warehouse, not missing coverage. Live viewership data provided by Twitch; the anticipation score is Aggrometer's own composite index (Steam wishlist rank + pre-release Twitch attention).
