### GET /v1/prices/buff163/float-buyorder

Buff163 Float Buyorder

Highest **Buff163 buy order per float range** (and per Fade % range,
Doppler phase or pattern tier) for every tracked skin, with the number
of buy orders in that range. Buff publishes these as aggregates, so
unlike the YouPin endpoint there is one entry per range, not one per
order.

Ranges are Buff's fixed buckets (e.g. `0.15-0.18`), closed on both ends.
Fade skins come as a matrix: float ranges, Fade ranges and every
float × Fade combination (`"any"` marks the axis that is not limited).

Use the filters to price a specific item:
- `float=0.153` keeps the ranges containing 0.153; `best_price_rmb` is
  then the highest buy order for that float.
- `fade=97.5` keeps the Fade ranges containing 97.5 (combined with
  `float` when both are given).
- `phase` (Doppler / Gamma Doppler) or `tier` (`T1`–`T4` for Case
  Hardened / Heat Treated, `T1`–`T10` Marble Fade, `T1`–`T6` Crimson
  Kimono) selects that variant. Items without such variants fall back
  to their plain ranges.

Without `phase`/`tier`, every variant is returned and `best_price_rmb`
covers only the plain (variant-less) ranges. Data refreshes about every
10 minutes.


**Parameters**

| Name | In | Required | Description |
|---|---|---|---|
| `market_hash_name` | query | optional | One or more skins (comma-separated or repeated, max 100). Omit for all skins. |
| `float` | query | optional | Only ranges that contain this float value (0–1). |
| `phase` | query | optional | Doppler phase of the item. |
| `fade` | query | optional | Fade % of the item (0–100); keeps the Fade ranges that contain it. |
| `tier` | query | optional | Pattern tier of the item (cannot be combined with phase). |
