# Sell Items (Self-Trade)

> Merchant sells skins from a Steam account to AssetPay in exchange for USD wallet credit.

# POST /secure/sell

Merchant-facing equivalent of [`POST /client/trading/deposit`](/api-reference/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`

## Response

Returns a full [`Trade`](/reference/types#trade) object with `source: "self"`. Self-trades are always treated as fully trusted — `preCredit` equals `totalPrice` and there is no collateral.

```json theme={null}
{
  "requestId": "...",
  "success": true,
  "data": {
    "id": "trade-uuid",
    "type": "deposit",
    "source": "self",
    "status": "initiated",
    "game": "730",
    "externalId": "self_sell_001",
    "merchantId": "merchant-uuid",
    "clientSteamID": "76561198012345678",
    "clientTradeUrl": "https://steamcommunity.com/tradeoffer/new/?partner=12345&token=ABCDEFGH",
    "items": [ /* ... */ ],
    "totalPrice": 10.75,
    "preCredit": 10.75,
    "pendingCredit": 0,
    "isInstant": true,
    "collateral": { "merchant": 0, "provider": 0 },
    "createdAt": "2026-05-14T12:00:00.000Z",
    "updatedAt": "2026-05-14T12:00:00.000Z"
  }
}
```

## 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`](/api-reference/trading/deposit#errors) 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.
