Hi you can use following query Athena CUR query

SELECT
	bill_payer_account_id,
	line_item_usage_account_id,
	line_item_operation,
	line_item_resource_id,
	product_product_family,
	product_servicename,
	line_item_line_item_description,
	pricing_unit,
	resource_tags_user_name,
	year,
	month,
	line_item_unblended_rate,
	sum(line_item_usage_amount) as Usage,
	sum(line_item_unblended_cost) as Cost
FROM
	"customer_cur_data"."customer_all"
where
	line_item_operation = 'VpcEndpoint'
	AND bill_payer_account_id in ('')
	and year='2023' and month in ('04')
	AND line_item_line_item_type NOT IN ('Tax','Refund','Credit')
	AND product_servicename = 'Amazon Virtual Private Cloud'
	group by 1,2,3,4,5,6,7,8,9,10,11,12

replace with actual account numbers and months. Download results and then you will get account wise resource with bytes transferred and usage hours. "VpcEndpoint-Bytes" represents data processed
