# The Steam API: game data, reviews, pricing, and player counts in one place

Jun 19, 2026 · 3 min read

Steam's official Web API is fragmented across at least a dozen separate interfaces, each with its own authentication model, underdocumented response format, and endpoint-specific API key requirement. Getting game metadata from one endpoint, user reviews from another, and pricing from a third means managing multiple auth flows and stitching together incompatible JSON shapes. SteamDB's enriched data — player counts, lowest-price history, patch logs, active sale alerts — isn't available from Valve at all. It lives behind a website.

The Anysite Steam API consolidates all of it. Ten endpoints across two namespaces (`/steam` for the Store, `/steamdb` for SteamDB) return structured JSON with a single `access-token` header. No Valve key, no session management, no DOM parsing.

## What the Steam API returns

The `POST /api/steam/apps` endpoint returns the full Store record for any game: name, genres, developer, publisher, metacritic score, pricing with discount percentage, DLC and package lists, achievement count, platform support, screenshots, and system requirements. Pass a numeric app ID or a Steam Store URL — the endpoint accepts both.

Reviews are a separate call. `POST /api/steam/apps/reviews` accepts `review_type` (`positive`, `negative`, or `all`) and a language filter. Each review object includes the author's playtime at review time, whether the copy was purchased on Steam (vs gifted or received for free), a `is_steam_purchase` flag, and a `weighted_vote_score` that Steam uses for ranking. These fields matter when you're doing sentiment analysis — a 200-hour player's negative review carries different weight than a 20-minute refund candidate.

## What does the SteamDB API add that Steam's API doesn't?

The Steam Store API doesn't expose current player counts, historical pricing, or sale intelligence. SteamDB does. The `POST /api/steamdb/apps` endpoint returns the same enriched record SteamDB shows on its app pages: `players_now`, `peak_24h`, `peak_all_time`, current price and lowest-ever price, review totals split by positive and negative, SteamDB tags, and Steam Deck compatibility tier.

The `POST /api/steamdb/charts` endpoint returns the live player-count leaderboard — rank, current players, 24h and all-time peaks for the top N games. Useful for tracking esports titles, measuring competitor game health, or building a live gaming dashboard. The `POST /api/steamdb/sales` endpoint returns currently discounted games with an `is_historical_low` boolean and a `min_discount` filter parameter. A 50%+ discount query against this endpoint powers a price-alert bot in about 30 lines of code.

## Pricing and what each endpoint costs

Prices differ by endpoint. Steam app details and Steam app search are the cheapest calls; reviews are charged per 100 results returned; SteamDB charts, patch notes, and promotions cost more per call. Each endpoint's price is listed on the [Steam](https://anysite.io/endpoints/steam/) and [SteamDB](https://anysite.io/endpoints/steamdb/) endpoint pages. The Anysite Starter plan covers 15,000 credits at $49/month; Growth covers 100,000 at $200.

## A minimal review-mining example

Search for a game, get its app ID, then pull negative reviews in English:

```
import requests

BASE = "https://api.anysite.io"
HEADERS = {"access-token": "YOUR_TOKEN", "Content-Type": "application/json"}

# Find the app ID
search = requests.post(f"{BASE}/api/steam/apps/search",
    headers=HEADERS, json={"term": "Cyberpunk 2077", "count": 1})
app_id = search.json()[0]["id"]

# Pull up to 200 negative English reviews
reviews = requests.post(f"{BASE}/api/steam/apps/reviews",
    headers=HEADERS,
    json={"appid": str(app_id), "count": 200,
          "review_type": "negative", "language": "english"})

for r in reviews.json():
    minutes = (r["author"] or {}).get("playtime_at_review") or 0
    print(minutes // 60, "hrs —", (r["text"] or "")[:80])
```

## What about the patch history and promotions endpoints?

`POST /api/steamdb/apps/patches` returns the build changelog indexed by SteamDB — each entry includes the patch title, a Unix timestamp, and a `has_patch_notes` flag (some builds ship silently without public notes). This is useful for competitive monitoring: correlate update frequency with player-count changes, or detect when a competitor ships a major content drop. The SteamDB platform itself is a well-known reference site for Steam data; their API documentation for the raw data points is sparse, which is why this endpoint exists.

`POST /api/steamdb/promotions` returns the current list of free-to-keep and limited-time giveaways on Steam. Each record includes `start_at` and `end_at` timestamps — enough to build a promotion-expiry alert without polling Steam directly.

## Authentication

All 10 endpoints use the same `access-token` header — no separate Valve key, no Steam session cookie, no additional setup. Get your token at [app.anysite.io](https://app.anysite.io/?ref=anysite.io).
