# Run Pricing for Items to Cart

Return the pricing information for each line item by invoking pricing rules. If line items are specified, they are priced. If line items are not specified, all of the items in the cart are priced.

```nolang
POST /v2/cpq/carts/{cart_ID}/price
```

:::note
If the value for `pagesize` parameter is not provided, it defaults to 20. To fetch or price more than 20 items, specify `pagesize` explicitly.
