Sell Items (Self-Trade)

Merchant-facing equivalent of POST /client/trading/deposit. Initiates a deposit trade where AssetPay receives the skins via Steam trade offer and credits the merchant’s USD wallet. There is no end-user — the trade URL is supplied per-request. Authentication: Merchant API Key (api-key header) Scope: CORE_ACCESS

Request

POST https://api.assetpay.gg/secure/sell
Content-Type: application/json
api-key: ap_...

  "items": [
    { "itemId": "a1b2c3d4-...", "price": 10.75 }
  ],
  "game": "730",
  "externalId": "self_sell_001",
  "isInstant": true
}

Body Parameters

Parameter	Type	Required	Description
`tradeUrl`	string	Yes	Steam trade URL of the account selling the items
`items`	array	Yes	Items to sell (min 1, max 250)
`items[].itemId`	string	Yes	Item ID from `/secure/inventory`
`items[].price`	number	Yes	Offer price in USD. Must match the current offer price.
`items[].amount`	number	No	Quantity for stackable Rust items (default `1`)
`game`	string	No	`"730"` or `"252490"`. Defaults to `"730"`.
`externalId`	string	No	Your unique tracking ID

Response

Returns a full Trade object with source: "self". Self-trades are always treated as fully trusted — preCredit equals totalPrice and there is no collateral.

Differences from `/client/trading/deposit`

Risk evaluation is skipped — merchant self-trades are fully trusted, so preCredit always equals totalPrice and pendingCredit is 0.
The per-client active/rolling deposit guard does not run on this route — only the per-merchant tier throttle limits self-trades.
The trade is persisted with source: "self", and the API response carries that field so you can distinguish self-trades from client trades.
Webhooks still fire on every state change.

Rate Limits

Merchant Status	Limit
Verified	5,000 requests / min
Unverified	50 requests / min

Errors

Same set as POST /client/trading/deposit minus TOO_MANY_ACTIVE_TRADES (per-client guard never runs). RATE_LIMITED (1005) can still fire if the merchant-tier limits above are exceeded. INVALID_TRADEURL (13) is common if the supplied tradeUrl is malformed.
