How to Get Case Hardened Tier and Float Price History
Updated
API reference: GET /v1/market/buff/latest · POST /v1/market/buff/history
BUFF Case Hardened tier and float price history is available through
POST /v1/market/buff/historyfrom May 19, 2026. The endpoint records separate OHLC for the item, tier, and exact float-range market.
A Tier 1 low-float item has two nested price effects. The tier separates its pattern class from the parent Case Hardened market, and the float bucket separates its wear from the tier-wide market.
The three BUFF buckets
For one Case Hardened item, the load-bearing comparison uses:
| Bucket | Market represented |
|---|---|
Parent base |
All BUFF listings for the ordinary Case Hardened item |
Variant base |
All BUFF listings in one tier, such as variant:t1 |
Variant float |
One float range inside that tier, such as variant:t1|float:0.15:0.18 |
Each bucket has current ask, avg_ask, bid, ask_volume, and
bid_volume. Historical points have OHLC for the three price fields plus the
last-observed volumes, bucket, open_time, and close_time.
Range bounds include min and exclude max. A float of 0.18 cannot use the
0.15:0.18 bucket. Float ranges also vary by item and tier, so the exterior
name alone is insufficient.
Resolve and query the exact range
Use GET /v1/market/buff/latest to select the Case Hardened item, then locate
the tier under variants by stable version (t1 through t4, or
singleblue when returned). Match the exact float to one of that tier's
float buckets and retain all three bucket_id values.
Request the base market_hash_name on the history endpoint and select those
same identifiers. Compare closing asks only at timestamps present in all three
series:
- Float bucket divided by tier base isolates the low-float premium within the tier.
- Float bucket divided by parent base gives the combined tier and float premium.
The BUFF history reference covers the nested item, variant, bucket, and point objects.

Limits on the valuation
- All three asks are active listing floors. They do not show that a completed sale occurred at either premium.
- The tier still groups many paint seeds. Exact pattern placement, play-side blue, stickers, and one item's precise float can move its value within the same tier-and-range bucket.
- Missing timestamps should be omitted from the matched comparison. Filling a gap from another tier or float range changes the market identity.
- Dedicated BUFF range history begins May 19, 2026 and supports
30m,1h, and1d; it does not provide earlier tier-and-float buckets.
