Files

File	Contents	Endpoint
`cs2_listing_prices_hourly.*`	Per-marketplace OHLC ask and bid prices	`/v1/prices/history`
`cs2_market_aggregate_hourly.*`	Cross-marketplace aggregate with `hourly_volume` and `total_supply`	`/v1/archive/history`

All timestamps are UTC. Monetary values are in USD.

Schema

`cs2_listing_prices_hourly.*`

One row per (item × variant × source × hour). Per-marketplace hourly OHLC listing prices.

Column	Type	Nullable	Description
`market_hash_name`	string	no	Steam market hash name.
`variant_version`	string	yes	Variant code (`p1`-`p4`, `ruby`, `sapphire`, `blackpearl`, `emerald`, `t1`-`t4`, `singleblue`); null for base items.
`variant_display_name`	string	yes	Human-readable variant name; null for base items.
`source`	string	no	`buff`, `youpin`, or `csfloat`.
`bucket`	timestamp	no	Start of the 1-hour bucket (UTC).
`open_ask`, `high_ask`, `low_ask`, `close_ask`	float	yes	OHLC ask prices (USD).
`ask_volume`	integer	yes	Listings at end of hour.
`open_bid`, `high_bid`, `low_bid`, `close_bid`	float	yes	OHLC bid prices (USD). Null for CSFloat.
`bid_volume`	integer	yes	Buy orders at end of hour. Null for CSFloat.
`sample_count`	integer	yes	Underlying 5-minute observations aggregated.
`open_time`, `close_time`	timestamp	yes	First/last observation timestamps in the bucket.

`cs2_market_aggregate_hourly.*`

One row per (item × variant × hour). Cross-marketplace aggregate. Shares market_hash_name, variant_version, variant_display_name, and bucket with the listing file.

Column	Type	Nullable	Description
`time`	timestamp	yes	Last observation timestamp.
`ask`, `bid`	float	yes	Aggregate ask/bid prices (USD).
`ask_volume`, `bid_volume`	integer	yes	Aggregate listing/order counts.
`hourly_volume`	float	yes	Completed sales in the hour (unique to this file).
`total_supply`	float	yes	Total known items in existence at end of hour (unique to this file).
`sample_count`	integer	yes	Underlying observations aggregated.

Variants

Variants appear as rows with the same market_hash_name as their base item but with variant_version and variant_display_name populated.

Family	Values
Doppler phases	`p1`, `p2`, `p3`, `p4`
Doppler finishes	`ruby`, `sapphire`, `blackpearl`, `emerald`
Case Hardened tiers	`t1`, `t2`, `t3`, `t4`
Case Hardened special	`singleblue` (Blue Gem)

Null semantics

—Missing rows: a row is not emitted if a source had no data for that item at that hour. For cross-marketplace comparisons, use an explicit join rather than assuming aligned rows.
—Null columns: CSFloat has no bid data, so open_bid, close_bid, bid_volume etc. are always null when source = 'csfloat'.

Quick start

python

import pandas as pd
import duckdb

prices = pd.read_parquet("cs2_listing_prices_hourly.parquet")
aggregate = pd.read_parquet("cs2_market_aggregate_hourly.parquet")

# DuckDB runs directly on the files
duckdb.sql("SELECT * FROM 'cs2_listing_prices_hourly.parquet' LIMIT 10")
