Live Steam concurrent-player counts and the most-played-games charts, with no key. This reads Valve's own public Steam charts and player-count endpoints and returns clean JSON: how many people are playing any game on Steam right now (by app id, with the game name resolved from the Steam store), the live leaderboard of the most-played games ranked by current concurrent players with today's peaks, and the most-played chart with week-over-week movement (current rank, last week's rank and the change). The live-engagement / player-activity layer for gaming dashboards, analytics, esports and games-market tools. Distinct from the Steam store reader, the SteamSpy ownership reader, the review-sentiment reader and the Steam Market price reader — this is the live "who is playing what right now" data. Live from Steam; short cache only.

Live prices from the Steam Community Market (steamcommunity.com/market), the largest virtual-item economy in gaming, read keyless from Steam's public market endpoints. Every day millions of dollars of CS2 skins, Dota 2 items, Team Fortress 2 hats and other in-game items change hands on Steam's marketplace at real, floating prices — a genuine commodity market for digital goods. The popular endpoint lists the most-listed items on the market for a game — the busiest part of the economy, each with its current lowest sell price (USD) and listing count. The search endpoint finds items by name within a game, sorted by price or popularity. The price endpoint returns the live price overview for one specific item: its lowest asking price, median sale price and 24-hour sold volume. This is the Steam Market cut — a distinct gaming-economy / virtual-item trading platform, separate from the Steam store, player-count and review feeds (steamspy, steamreviews) and from the other gaming and marketplace feeds in the catalogue; it is the trading-price layer for virtual items, comparable to a commodity exchange for digital goods. Games are addressed by friendly alias (cs2, dota2, tf2, rust, pubg) or numeric Steam appid. Prices are in US dollars and are the real, live numbers Steam shows; Steam rate-limits market calls, so a protective cache fronts the upstream and stale data is served if the limit is hit. Keyless.

Live Linux and Steam Deck compatibility plus popularity for Steam games, from the public ProtonDB and Steam feeds — no key, nothing stored. The "can I play it on Linux / Steam Deck, and is anyone playing it" view of a game: the crowd-sourced ProtonDB compatibility tier together with the live concurrent-player count, distinct from the other game and platform APIs in the catalogue. The game endpoint returns a full picture for a title — its Steam name, genres and release date, the ProtonDB compatibility tier (platinum, gold, silver, bronze or borked) with the community confidence, score and report count, the trending and best-reported tiers, and the live player count. The search endpoint resolves a game name to its Steam app id and other matches, so you can find the id to query. The players endpoint returns just the live concurrent-player count for a game. Build Steam Deck compatibility checkers, Linux gaming dashboards, "is it playable" widgets and game-popularity trackers on top of real ProtonDB and Steam data. Look up a game by Steam app id (appid=1245620) or by name (name=elden ring); ProtonDB tiers run from platinum (flawless) down to borked, and player counts are live.

Live Steam user-review sentiment as an API — what players really think of any game on Steam, served from Steam's public review data. For any game, looked up by its Steam app id or by name, it returns the aggregate review summary (total reviews, positive and negative counts, the positive percentage and Steam's own rating label such as "Very Positive" or "Mixed"), plus a sample of recent reviews with their text, whether the author recommends the game, helpful and funny votes, the author's playtime and the review language. Get the full reviews feed, the lightweight sentiment summary, or search Steam to resolve a game name to its app id. The community-sentiment layer for gaming, review and dashboard apps. Live, no key. Distinct from a Steam store-catalogue API — this returns the user reviews and rating sentiment, not the store listing.

Steam game ownership and player analytics as an API, powered by SteamSpy — clean JSON, no key. Look up any Steam game by app id for its estimated owners, current concurrent players, average and median playtime (all-time and last two weeks), price and discount, positive/negative review counts and review score, developer, publisher, genre, languages and top community tags. Pull the top-100 lists — games by current players, by all-time playtime and by estimated owners — and list the top games in any genre or with any tag. Live market data straight from SteamSpy. Distinct from the Steam store: this is the ownership and engagement layer — ideal for game-market research, indie-dev competitor analysis, trend dashboards and charts. 6 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.

Steam-boiler engineering maths as an API, computed locally and deterministically — the three numbers a boiler operator, plant engineer or steam-system designer actually works with. The boiler-hp endpoint converts a required heat output into boiler horsepower (heat ÷ 33,475 BTU/hr, the standard definition), the equivalent steam output in pounds per hour "from and at" 212 °F (34.5 lb/hr per BHP) and the output in kilowatts — a 1,000,000 BTU/hr load is about 29.9 BHP or 1,031 lb/hr of steam. The factor-of-evaporation endpoint gives the real capacity for your feedwater: the factor = (the total heat of the steam − the feedwater heat) ÷ 970.3, always greater than one because the boiler must add the sensible heat to bring water up to boiling, so a boiler rated "from and at" 212 °F actually makes less with 60 °F feedwater — which is exactly why preheating feedwater with an economiser raises capacity and saves fuel. The blowdown endpoint gives the continuous blowdown rate to hold the boiler water within its dissolved-solids limit: blowdown = steam × feedwater TDS ÷ (boiler limit − feedwater TDS), with the cycles of concentration and the blowdown as a percentage of feedwater — better feedwater means more cycles, less blowdown and less wasted hot water. Everything is computed locally and deterministically, so it is instant and private. Ideal for boiler operators, steam-plant and HVAC engineers, energy auditors, water-treatment specialists and process-engineering tools. Pure local computation — no key, no third-party service, instant. Engineering estimates — verify against the manufacturer data and local code. 3 compute endpoints. For moist-air properties use a psychrometric API; for compressed air use a compressor API.

The Steam store as an API. Search Steam for games and get each game's full details — short description, genres and categories, developers and publishers, release date, platforms (Windows/macOS/Linux), Metacritic score, price and discount, header image and screenshots — and its player-review summary, from the famous "Overwhelmingly Positive" / "Mixed" rating down to the exact positive percentage and total review count, plus a few recent reviews. Look up any game by its Steam app id (e.g. 620 for Portal 2, 1245620 for Elden Ring). Prices are country-specific. Ideal for game directories, review and rating dashboards, Discord bots, wishlists and gaming apps. Public Steam store data.

PC video-game prices and discounts across 30+ digital stores as an API — Steam, GOG, Epic Games, Humble, GreenManGaming, Fanatical and more, powered by CheapShark. Search games by title to get the cheapest current price; look up a game to see every store's deal side by side (price, retail price, % off and a buy link) plus its lowest-ever price; or browse the current best deals filtered by store or maximum price and sorted by deal rating, savings, price, recency or Metacritic score. Ideal for game-deal sites, price-tracker bots, gaming dashboards, browser extensions and Discord bots. Prices in USD. Open data from CheapShark.
