## Snapshot

**Endpoint:** `GET /commodities/snapshot/:symbol`

Combined bid/ask, last price, previous daily close, and derived change metrics in one normalized commodity snapshot.

### Path parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `symbol` | string | Yes | Enabled commodity symbol (e.g. XAUUSD, WTIUSD). Trimmed and uppercased before lookup. Discover tickers with GET /commodities/symbols. |

### Request

```bash
curl -sS "https://api.tickerlayer.com/commodities/snapshot/WTIUSD" \
  -H "x-api-key: <YOUR_API_KEY>"
```

```python
import requests

res = requests.get(
    "https://api.tickerlayer.com/commodities/snapshot/WTIUSD",
    headers={"x-api-key": "<YOUR_API_KEY>"},
)
print(res.json())
```

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

```go
req, _ := http.NewRequest("GET", "https://api.tickerlayer.com/commodities/snapshot/WTIUSD", nil)
req.Header.Set("x-api-key", "<YOUR_API_KEY>")
```

### Response

```json
{
  "symbol": "WTIUSD",
  "bid": 71.22,
  "ask": 71.25,
  "bid_size": 58,
  "ask_size": 55,
  "last_price": 71.235,
  "last_timestamp": 1743512400000,
  "prev_close": 70.90,
  "change": 0.335,
  "change_percent": 0.472
}
```

### Notes

`last_size` appears when a trade size is available in the consolidated snapshot; otherwise it is omitted from the payload. `change_percent` is `null` when `prev_close` is zero or unavailable. An unknown symbol or an all-null snapshot returns `404`.
