Response
GET /client/market for the full field list and the Item type.
Items sourced from the AssetPay autoseller pool (self-owned, instant delivery) additionally carry previewToken (Steam inspect/preview token) and botInfo (the holding bot). Third-party marketplace listings expose an inspect link upstream and have no previewToken.
