Steam Games API — search, details, players & reviews (no key)

Steam store data as a clean HTTP API (and MCP tool): search games, get full details (price, genres, platforms, Metacritic, release date, description, screenshots), the current live player count, and the review summary (score + positive/negative counts). Perfect for game trackers, price/deal tools, dashboards and agents. No API key. Pay per query.

• 🔎 Search — find games by name with price and Metascore.
• 🎮 Details — price (per storefront), genres, platforms, developers/publishers, Metacritic, release date, screenshots, description.
• 👥 Players — the current number of people playing a game right now.
• ⭐ Reviews — overall review score, description ("Overwhelmingly Positive"), and positive/negative totals.
• 💵 Pay per query · no key.

The use case it was built for

Build a "what's popular on Steam" panel, track a game's live player count, compare prices across storefronts, or let an agent answer "how are the reviews for Portal?". Clean, typed data with images.
