Steam Store Game Reviews Full History Scraper

Scrape the complete review history for any Steam game using Steam's official cursor-paginated JSON API. Unlike competitors that return a single page, this actor exhausts the full cursor chain — retrieving every review for titles with hundreds of thousands of entries.

What you get

Each output record includes the full review body plus reviewer-quality signals ideal for brigade detection:

• Review content — full text, recommended/not, language, timestamps
• Reviewer signals — total games owned, prior review count, playtime at time of review (key for detecting low-effort reviews from new accounts)
• Engagement metrics — helpful votes, funny votes, comment count, Steam-weighted helpfulness score
• Purchase context — Steam purchase vs. external key, received for free, Early Access flag
• Per-game aggregate — review score, score description (e.g. "Overwhelmingly Positive"), total positive, negative, and total reviews (joined onto every row for easy analysis)

Input

Field	Type	Default	Description
appIds	string[]	["440"]	Steam app IDs. Find the ID in the store URL: store.steampowered.com/app/440/ → 440
maxItems	integer	10	Max reviews per game. Set to 0 to exhaust all reviews (may be slow for popular titles with 1M+ reviews)
language	string	all	Language filter: all, english, schinese, russian, etc.
reviewType	string	all	all, positive, or negative
purchaseType	string	all	all, steam, or non_steam_purchase
dateRangeStart	string	—	Optional ISO date YYYY-MM-DD — only include reviews created on or after

Use cases

• Review-bomb detection — filter by date range + author_num_games_owned / author_playtime_at_review_min to identify coordinated low-quality reviews
• Sentiment tracking over time — combine date range filters with full history to build time-series sentiment charts
• Competitive research — compare game_review_score_desc and positive/negative ratios across competing titles
• QA & community signals — extract the most-voted reviews by votes_up for customer feedback analysis

Rate limits & performance

Steam's review API is unauthenticated and generous. The actor uses a 350ms inter-request delay and fetches 100 reviews per page. For a title with 100,000 reviews expect approximately 1,000 API calls; with maxItems set the run completes in seconds.

Multiple games

Pass multiple app IDs to process them in a single run:

{
  "appIds": ["440", "570", "730"],
  "maxItems": 500,
  "language": "english"
}

Each app is processed sequentially; maxItems is applied per game.
