### FLP/sFLPトークン価格取得

{% stepper %}
{% step %}
SDKの使用（高度な統合）

{% code overflow="wrap" %}

```typescript
const getLpTokenPrices = async () => {
    await flashClient.loadAddressLookupTable(POOL_CONFIG)
    const stakedLpPrice = await flashClient.getStakedLpTokenPrice(POOL_CONFIG.poolAddress, POOL_CONFIG); // sFLP price
    const compoundingLPTokenPrice = await flashClient.getCompoundingLPTokenPrice(POOL_CONFIG.poolAddress, POOL_CONFIG); // FLP price

    console.log('stakedLpPrice :>> ', stakedLpPrice);
    console.log('compoundingLPTokenPrice :>> ', compoundingLPTokenPrice);
}
```

{% endcode %}

{% endstep %}

{% step %}
APIの使用（迅速で簡単）

すべてのプールの価格データを取得するには、以下のエンドポイントをクエリしてください：

```
https://api.prod.flash.trade/earn-page/data
```

{% endstep %}
{% endstepper %}

\
\&#xNAN;**✅** レスポンス形式（例）

レスポンスは`pools`の配列を含むJSONオブジェクトであり、それぞれがユニークなFLPプールを表しています。各キーの意味は以下の通りです：

| フィールド                | 説明                                     |
| -------------------- | -------------------------------------- |
| `poolAddress`        | 流動性プールのユニークなオンチェーンアドレス                 |
| `aum`                | このプールの運用資産（USD建て）                      |
| `flpTokenSymbol`     | 複利運用FLPトークンのシンボル（例：`FLP.1`、`FLP.2`）    |
| `sFlpTokenSymbol`    | ステークドFLPトークンのシンボル（例：`sFLP.1`、`sFLP.2`） |
| `flpDailyApy`        | 複利運用FLPトークンの日次APY（自動再投資）               |
| `flpWeeklyApy`       | 複利運用FLPトークンの週次APY                      |
| `flpWeeklyApr`       | 複利運用FLPトークンの週次APR（非複利運用）               |
| `sFlpDailyApr`       | ステークドFLPトークンの日次APR（非複利運用）              |
| `sFlpPrice`          | ステークドFLPトークンの現在価格                      |
| `flpPrice`           | 複利運用FLPトークンの現在価格                       |
| `sFlpPriceWithYield` | 利回りが評価に含まれる場合のsFLPトークンの導出価格            |

### **🔎 使用方法**

#### トークン価格を取得するには：

* `flpTokenSymbol`（例：`"FLP.1"`）または`poolAddress`を照合して、希望するプールを特定します。
* 複利運用FLPトークンには`flpPrice`を、ステーク版には`sFlpPrice`を使用します。

これは、SDKのセットアップやブロックチェーンのクエリなしに、リアルタイムの価格設定と利回りデータを必要とするフロントエンドやダッシュボードにとって最も簡単な方法です。
