FAQ

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.
