Sales History API 暴露 Steam 为每件市场物品追踪的每日价格历史。用它在投资组合仪表盘上驱动蜡烛图，或检测价格趋势。

What granularity is the history?

Daily snapshots. One row per day with the price observed at the snapshot time.

How far back does history go?

We keep at least 90 days of daily snapshots for every active item, often much more for popular items.

Can I bulk-fetch history?

Yes — POST to /steam/api/items/history with a list of market_hash_names for batch retrieval.

One key, every Steam endpoint.
