# Batch Token Compute Unit Cost

### Batch CU Cost

**Formula:**

> Batch CU Cost = N^exp × Base CU Cost

Where:

* **N**: Batch number.
* **exp**: Batch multiplier exponent.
  * **0.5** for **Blockchain API** endpoints.
  * **0.8** for **all other API groups**.
* **Base CU Cost**: The CU cost of requesting a single token using the corresponding multiple-token endpoint (different from the CU cost of the single-token endpoint).
* The **Batch CU Cost** is rounded up to the nearest whole number (0 decimal places).

### Examples

| API Name                | Endpoint                                 | Base CU Cost | exp | Max Batch Size |
| ----------------------- | ---------------------------------------- | -----------: | --: | -------------: |
| Token Multi Price       | `/defi/multi_price`                      |            3 | 0.8 |            100 |
| Account Detail Multiple | `/blockchain/v1/account/detail/multiple` |            5 | 0.5 |            100 |

#### Example 1: DeFi API

Request **N = 10** tokens using `/defi/multi_price`:

> Batch CU Cost = 10^0.8 × 3 = 18.93 → **19 CU**

#### Example 2: Blockchain API

Request **N = 100** accounts using `/blockchain/v1/account/detail/multiple`:

> Batch CU Cost = 100^0.5 × 5 = 10 × 5 = **50 CU**

**Notes**

* Using a batch endpoint is always more cost-efficient than making the equivalent number of single-endpoint requests.
* Users should consider purchasing a Business plan to access batch endpoints.
* The larger the batch size (**N**), the greater the effective discount. However, each endpoint has a maximum supported batch size (`n_max`), which must not be exceeded.
