How to Get Gamma Doppler Price History
Updated
API reference: POST /v1/prices/history
POST /v1/prices/historyreturns Gamma Doppler ask and available bid OHLC separately for Phase 1-4 and Emerald. General history starts December 24, 2025; CSFloat bids start July 18, 2026.
The parent Gamma Doppler series is not phase history. A valid phase comparison keeps each version and marketplace source separate across time.
Variant OHLC structure
The requested base item can return variants entries for p1, p2, p3, p4, and emerald. Every variant has a chronological data[] array of UTC buckets.
A source object can include open, high, low, and close values for asks and, where supported, bids. ask_volume and bid_volume are last-observed order counts when that source supports them. sample_count counts observations. open_time and close_time show the actual observation window inside the fixed bucket boundary.
Skinport is ask-only. CSFloat and C5Game have no bid_volume. Variant source objects appear only where data exists.
Request one or more phase histories
Send up to 100 base market_hash_name values to POST /v1/prices/history. Choose sources and an interval, then select the desired version under variants.
Use 5m for up to 14 days, 30m for 90 days, 1h for 365 days, or 1d for longer periods. Compare phase closes only across matching interval boundaries and source definitions.
For current phase quotes, use GET /v1/prices/latest. CSFloat also provides daily phase completed-sale aggregates from 2022 where archive coverage exists.

Historical interpretation
close_askis the last observed listing floor, not a completed-sale price.sample_countis observation coverage. It is not purchase volume.- Emerald can be much thinner than Phase 1-4. Missing buckets should remain gaps.
- Steam has no phase-specific Community Market rows, so its parent history cannot be assigned to variants.
- General OHLC begins December 24, 2025, while CSFloat bid fields begin July 18, 2026. No request interval can extend either boundary earlier.
