Youpin only provides sale prices, but you can estimate a minimum volume by counting the occurrence of sales within a given period.

Approximately 16,000 items are supported (anything at or above `liquid` on [GET /v1/liquidity/items](/docs/liquidity-items)), including Doppler & Case Hardened variant items.

This endpoint is available on the `scale` plan.
