Aggrometer tools (8)

write = sends, deletes, buys or posts
  • aggro_boardFree

    Aggrometer's signature metric: aggro = live Twitch viewers / concurrent Steam players, same hour, per game (min 500 players). Above 1.0 means more people watch than play — spectacle games, watch-to-learn genres. A sudden aggro jump is an early attention signal.

  • game_detailFree

    Full profile of one game by Steam app id: hourly player history, Twitch viewer history, daily viewer-hours, price/discount history, top-seller rank appearances, clips-per-day virality, review counts and review-activity buckets back to launch, Wikipedia pageview history (monthly since 2018 + daily), developer news velocity, achievement-completion depth, and metadata (genres, developer, publisher). Use search_games first if you only know the name.

  • genre_rollupFree

    Every Steam genre aggregated: game count, combined players, combined live viewers, genre-level aggro ratio, and combined hype (anticipation) of the genre's unreleased games. The whitespace signal: high players + low hype = an underserved genre; low players + high hype = a wave arriving.

  • get_summaryFree

    Warehouse status: how many games are tracked, hours of history recorded, snapshot counts, and data freshness timestamps. Call this first to understand data coverage.

  • hype_boardFree

    Aggrometer Anticipation Index: top-wishlisted unreleased Steam games scored with pre-release Twitch attention and Wikipedia attention surges (score = wishlist-rank points + log-scaled live viewers + log-scaled pageview surge vs 30-day average). A relative index - compare games against each other; week-over-week change is the launch-anticipation signal.

  • search_gamesFree

    Find games in the tracked catalog by name (substring match). Returns app ids for use with game_detail, plus current player counts.

  • top_playedFree

    Top 100 games by current Steam concurrent players (updated hourly). Optionally scoped to one Steam genre.

  • top_watchedFree

    Top 100 games by current live Twitch viewership (15-min updates). Optionally scoped to one Steam genre.

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.

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).
