## Last trade

**Endpoint:** `GET /stocks/trade/last/:symbol`

Latest executed trade from the aggregated tape when present; when the live tape snapshot is empty, price and timestamp fall back to the consolidated quote mid.

### Path parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `symbol` | string | Yes | Market-qualified symbol (CC:SYMBOL, e.g. US:AAPL, DE:BMW, TR:THYAO). Plain tickers are rejected. Discover enabled rows via GET /stocks/symbols (optional ?market=CC filter). |

### Request

```bash
curl -sS "https://api.tickerlayer.com/stocks/trade/last/US:AAPL" \
  -H "x-api-key: <YOUR_API_KEY>"
```

```python
import requests

res = requests.get(
    "https://api.tickerlayer.com/stocks/trade/last/US:AAPL",
    headers={"x-api-key": "<YOUR_API_KEY>"},
)
print(res.json())
```

```javascript
const res = await fetch("https://api.tickerlayer.com/stocks/trade/last/US:AAPL", {
  headers: { "x-api-key": "<YOUR_API_KEY>" },
});
const data = await res.json();
console.log(data);
```

```go
req, _ := http.NewRequest("GET", "https://api.tickerlayer.com/stocks/trade/last/US:AAPL", nil)
req.Header.Set("x-api-key", "<YOUR_API_KEY>")
```

### Response

```json
{
  "symbol": "US:AAPL",
  "price": 214.23,
  "size": 400,
  "timestamp": 1743512400000
}
```

### Notes

`503 market data temporarily unavailable` when no trade can be served yet. `size` may occasionally be null: the print carried no size, or the value came from a quote-only fallback.
