Query Parameters

Parameter	Type	Default	Description
`game`	integer	`730`	`730` (CS2) or `252490` (Rust). Any value other than `252490` returns CS2
`search`	string	-	Search by item name (max 100 chars)
`sort`	string	-	`relevance`, `priceAsc`, `priceDesc`, `nameAsc`, or `nameDesc`
`minPrice`	number	-	Minimum price filter (USD, `0` or more)
`maxPrice`	number	-	Maximum price filter (USD, `0` or more)
`page`	number	`1`	Page number
`perPage`	number	`50`	Items per page (1–1000), or `-1` to return every matching item
`source`	string	-	CS2 only. Set to `internal` to restrict results to the AssetPay pool, or `external` to restrict them to third-party marketplace listings (refreshed every 5 minutes). Omit for both. Ignored when `development` is set.
`development`	boolean	`false`	Sandbox flag. When `true` (or `1`), every returned item is stamped with instant delivery, a random `assetId`, a placeholder `previewToken`, and a synthetic holding `botInfo` so you can build against the full item shape using cheap real listings. Third-party listings are limited to instant-delivery rows, and the `source` filter is ignored.

Response

{
  "requestId": "...",
  "success": true,
  "data": {
    "items": [ /* InventoryItem[] */ ],
    "count": 1523
  }
}

See GET /client/market for the full field list and the Item type. CS2 rows also carry itemId, the parent catalog id. Pass it to GET /secure/market/item to list that item’s individual listings. Items sourced from the AssetPay internal pool (self-owned, instant delivery) additionally carry botInfo (the holding bot). previewToken (Steam inspect/preview token) is present on pool items, and on third-party marketplace listings when the marketplace provides one. To keep results current without polling, subscribe to the WebSocket Market Updates event. It pushes internal-source item and price changes in the same item shape, priced for your account.
