Get Inventory (Self-Trade) - AssetPay

Returns the Steam inventory for the account identified by the supplied tradeUrl. There is no client-authentication step on this path — the merchant API key authenticates the call, and the Steam account is derived per-request from the trade URL. Authentication: Merchant API Key (api-key header) Scope: CORE_ACCESS

collateral is always 0 for self-trade callers — instant credit isn’t applicable when the merchant is trading with itself. See the Instant Credit guide for the client-flow behavior.
