# Multi Factor Compute Unit Cost

This CU pricing model applies to the following endpoints:

| API                       | Endpoint                           |
| :------------------------ | :--------------------------------- |
| Liquidity OHLC - Pair     | `/defi/v3/liquidity/ohlc/pair`     |
| Liquidity OHLC - Token    | `/defi/v3/liquidity/ohlc/token`    |
| Liquidity History - Token | `/defi/v3/liquidity/history/token` |

<br />The CU (compute unit) cost is calculated dynamically based on three request parameters:

* **Resolution** – the requested candle interval.
* **Depth** – the number of candles requested (`limit`).
* **Lookback** – the historical time range implied by the request.

The calculation is performed **from the request parameters**, **not** from the actual number of records returned.

**💡 CU Formula**

```text theme={null}
CU = Base CU (Resolution) × Depth Multiplier × Lookback Multiplier × Limit
```

where:

```text theme={null}
lookback_days ≈ limit × resolution_in_days
```

### 1. Resolution Base CU

| Resolution | Description     | Base CU |
| :--------- | :-------------- | ------: |
| \< 1H      | High resolution |      20 |
| \< 1D      | Intraday        |      50 |
| ≥ 1D       | Daily+          |    2000 |

### 2. Depth Multiplier

| Candles per Request | Multiplier |
| :------------------ | ---------: |
| ≤ 100               |         ×1 |
| 101 – 300           |         ×2 |
| 301 – 500           |         ×3 |

### 3. Lookback Multiplier

| Lookback Range | Description               | Multiplier |
| :------------- | :------------------------ | ---------: |
| \< 1 day       | Realtime / Intraday       |         ×1 |
| 1 – 100 days   | Standard Historical       |       ×1.5 |
| > 100 days     | Deep Historical / Archive |         ×3 |

ℹ️ **Examples**

### Example 1 — Realtime (no lookback multiplier)

Request:

* Resolution: **1m**
* Limit: **500**
* Lookback: **500 minutes (\~0.35 day)**

Calculation:

```text theme={null}
Base CU = 20
Depth Multiplier = ×3
Lookback Multiplier = ×1

CU = 20 × 3 × 1 = 60 CU
```

***

### Example 2 — Standard historical lookback

Request:

* Resolution: **1H**
* Limit: **240**
* Lookback: **240 hours (10 days)**

Calculation:

```text theme={null}
Base CU = 50
Depth Multiplier = ×2
Lookback Multiplier = ×1.5

CU = 50 × 2 × 1.5 = 150 CU
```

***

### Example 3 — Deep historical archive

Request:

* Resolution: **1D**
* Limit: **365**
* Lookback: **365 days**

Calculation:

```text theme={null}
Base CU = 200
Depth Multiplier = ×3
Lookback Multiplier = ×3

CU = 200 × 3 × 3 = 1,800 CU
```

***

### Example 4 — Large intraday historical query

Request:

* Resolution: **15m**
* Limit: **500**
* Lookback: **7,500 minutes (\~5.2 days)**

Calculation:

```text theme={null}
Base CU = 20
Depth Multiplier = ×3
Lookback Multiplier = ×1.5

CU = 20 × 3 × 1.5 = 90 CU
```
