## Snapshot

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

Combined bid/ask, last trade price, previous daily close, and derived change metrics in a single call.

### 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/snapshot/US:AAPL" \
  -H "x-api-key: <YOUR_API_KEY>"
```

```python
import requests

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

```javascript
const res = await fetch("https://api.tickerlayer.com/stocks/snapshot/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/snapshot/US:AAPL", nil)
req.Header.Set("x-api-key", "<YOUR_API_KEY>")
```

### Response

```json
{
  "symbol": "US:AAPL",
  "bid": 214.22,
  "ask": 214.25,
  "bid_size": 1200,
  "ask_size": 800,
  "last_price": 214.23,
  "last_size": 400,
  "last_timestamp": 1743512400000,
  "prev_close": 212.10,
  "change": 2.13,
  "change_percent": 1.004
}
```

### Notes

`last_size` is present only when a native trade size is available. `change_percent` is `null` when `prev_close` is zero or unavailable. An all-null snapshot returns `503`.
