How to Get Steam Community Market Sale Volume

Updated

API reference: POST /v1/archive/steam

POST /v1/archive/steam returns native Steam purchase volume paired with median sale price, daily from April 26, 2013 and hourly from May 9, 2026.

Purchase volume counts completed sales in each native Steam bucket. It is different from the current ask_volume and bid_volume, which count active orders.

Steam volume coverage#

At 1d, the archive covers daily purchase counts from April 26, 2013. At 1h, it covers hourly counts from May 9, 2026. Each bucket includes:

Field Meaning
bucket Native Steam interval start
price Median completed-sale price
volume Number of purchases

The archive refreshes every 8 hours for liquid items and daily for other items. Prices are USD Steam wallet value.

Query purchase counts#

Send up to 100 exact regular market_hash_name values to POST /v1/archive/steam with an inclusive start, exclusive end, and 1h or 1d interval. Sum volume across the desired buckets to calculate purchases over the range.

Keep the median price beside volume when comparing active and quiet periods. Multiplying the median by purchases does not recover exact traded value because the individual transaction prices are not returned.

For current order counts, use GET /v1/prices/latest. For per-level quantities, use the full Steam orderbook.

Volume caveats#

  • Daily and hourly start dates differ. Hourly requests before May 9, 2026 return no hourly sale buckets.
  • Archive volume is purchases; current ask_volume and bid_volume are active orders.
  • The archive supports regular items only. Variant requests return unsupported_variant.
  • Missing buckets should not be converted to zero unless the downstream method explicitly defines that transformation.
  • Steam sale prices are wallet value even when purchase volume is used as a direct activity signal.

The Steam archive docs provide the complete response and partial-success behavior.
