Why it exists

Steam trend data, without the plumbing

Steam's own Web API does not expose player-count history, and SteamDB is a website you are not supposed to scrape. Trends API gives you the same class of data as clean JSON: how many people play a game, month over month, with growth computed and a live most-played feed.

Player counts answer the question hype cannot: is anyone still playing? A game can dominate YouTube for a week and lose half its players in a month. Querying both sources here, on the same 0-100 scale, separates launch noise from durable traction.

FAQ

Common questions

What Steam data does Trends API provide?

Monthly concurrent player counts for any game as a normalized time series, growth percentages over 3M/6M/12M/5Y windows, and the live Steam Most Played feed.

Do I need a Steam Web API key?

No. One Trends API key covers Steam and every other source.

How is this different from SteamDB?

SteamDB is a website you scrape against its terms. Trends API gives you the same class of data as clean JSON with normalization and growth already computed, in the same response shape as 13 other sources.

Can I compare a game's Steam players with its YouTube buzz?

Query steam alongside youtube or google search for the game title and compare normalized scores. Player counts and content interest often diverge in interesting ways.

How far back does history go?

Up to 5 years of monthly data on every plan, Free included.
