Output schema

One dataset item per review, these 14 keys: appId (int), reviewId (str), url, text, language, date (ISO 8601 UTC), votedUp (bool), votesUp, votesFunny, playtimeForeverMin, playtimeAtReviewMin (int minutes), lexiconScore, sentimentScore (float), sentiment (str).

{"appId": 570, "reviewId": "123456", "url": "https://steamcommunity.com/profiles/7656119800000000/recommended/570/", "text": "great fun game", "language": "english", "date": "2026-03-01T12:00:00Z", "votedUp": true, "votesUp": 3, "votesFunny": 0, "playtimeForeverMin": 5400, "playtimeAtReviewMin": 1200, "lexiconScore": 1.0, "sentimentScore": 1.0, "sentiment": "positive"}

Sentiment method

Pure stdlib, no external API. Text is lowercased into word tokens and matched against embedded lists of 40+ positive and 40+ negative gaming words (fun, masterpiece, addictive / boring, buggy, crash, refund, ...). A negator (not, no, never, don't, isn't, wasn't, can't) within the 2 previous tokens flips that word.

• lexiconScore = (pos - neg) / max(1, pos + neg), range [-1, 1], 0 when no hits
• sentimentScore = round(0.5 * (1 if votedUp else -1) + 0.5 * lexiconScore, 3)
• sentiment: positive if score > 0.2, negative if < -0.2, else mixed

Pricing

Pay per event: review = $0.001 per review pushed. The run stops cleanly when your max-charge limit is reached.

Limits

• Public reviews only.
• Steam rate limits apply: 429/5xx retried up to 3 times with backoff, 0.5-1 s pause between pages.
• filter=recent walks back in time, so old date windows cost many requests.
• The lexicon is English-only; other languages rely mostly on votedUp.
• Max per run = maxReviews, total across games.
