# API Update - List Endpoint Integration

## ✅ Changes Implemented

### API Endpoint Changed

**Before:**
```
https://ccapi.rerrkvifj.com/finance-earn-center/current/financing/info?currentFinancingId=267
```

**After:**
```
https://ccapi.rerrkvifj.com/finance-earn-center/current/financing/list?status=&assetCode=&pageNo=1&pageSize=10&total=1
```

### Data Extraction Logic

**Before:**
- Directly accessed `$apiData['data']` fields
- Assumed single product response

**After:**
- Fetches list of products
- Searches for BTC product by `assetCode === 'btc'`
- Extracts data from matched product

### PHP Code Flow

```php
1. Fetch list API
   ↓
2. Parse JSON response
   ↓
3. Loop through resultList
   ↓
4. Find product where assetCode === 'btc'
   ↓
5. Extract BTC product data
   ↓
6. Use in dashboard display
```

## Data Mapping

### APY (Compound)
- **API Field**: `compoundInterestAnnualYield`
- **Example Value**: `"0.012069"`
- **Display**: `1.2069%` (multiplied by 100)
- **Location**: Top right of BTC section

### 10K Share/Day
- **API Field**: `revenuePerTenThousand`
- **Example Value**: `0.3`
- **Display**: `0.3000 BTC`
- **Location**: Left column under product name

### Participated
- **API Field**: `progressBar`
- **Example Value**: `0.4178`
- **Display**: `41.78%` (multiplied by 100)
- **Location**: Right column under product name

## API Response Structure

```json
{
  "data": {
    "resultList": [
      {
        "id": 267,
        "name": "BTC Deposite to Mining DeFi",
        "assetCode": "btc",
        "compoundInterestAnnualYield": "0.012069",
        "revenuePerTenThousand": 0.3,
        "progressBar": 0.4178,
        "totalCurrentScale": "584.9304",
        "totalRealizeProfit": "16.4454",
        "leastTake": 0.01,
        "interestPattern": 1,
        ...
      }
    ]
  }
}
```

## Display Locations

### BTC Deposite to Mining DeFi Section

```
┌─────────────────────────────────────────┐
│ BTC Deposite to Mining DeFi    APY: 1.2069% │ ← compoundInterestAnnualYield
│ [Started]                                │
├─────────────────────────────────────────┤
│ 10K Share/Day    │  Participated        │
│ 0.3000 BTC       │  41.78%              │ ← progressBar
│ ↑                   ↑                    │
│ revenuePerTenThousand                   │
└─────────────────────────────────────────┘
```

## Percentage Conversion

### Progress Bar
```php
$progressBar = 0.4178;  // From API
$displayValue = $progressBar * 100;  // 41.78
echo number_format($displayValue, 2) . '%';  // "41.78%"
```

### APY (Compound)
```php
$compoundInterestAnnualYield = "0.012069";  // From API
$displayValue = $compoundInterestAnnualYield * 100;  // 1.2069
echo number_format($displayValue, 4) . '%';  // "1.2069%"
```

## Product Details Section

All data in the "Product Details" section also comes from the same BTC product:

| Field | API Source | Display |
|-------|------------|---------|
| Current Scale | `totalCurrentScale` | 584.9304 BTC |
| Realized P&L | `totalRealizeProfit` | 16.4454 BTC |
| Min investment | `leastTake` | 0.01 BTC |
| Interest-bearing model | `interestPattern` | T + 1 |

## Fallback Handling

If API fails or BTC product not found:
```php
$btcProduct = null;

// Uses default values
$compoundInterestAnnualYield = $btcProduct['compoundInterestAnnualYield'] ?? '0.012069';
$revenuePerTenThousand = $btcProduct['revenuePerTenThousand'] ?? 0.3;
$progressBar = $btcProduct['progressBar'] ?? 0.4178;
```

## Testing

### To Verify:
1. Open dashboard: `http://localhost/frontend/dashboard.php`
2. Check BTC section displays:
   - **APY (Compound)**: Should show percentage (e.g., 1.2069%)
   - **10K Share/Day**: Should show BTC amount (e.g., 0.3000 BTC)
   - **Participated**: Should show percentage (e.g., 41.78%)

### Console Debugging:
```php
// Add to dashboard.php for debugging
error_log("BTC Product: " . print_r($btcProduct, true));
error_log("Progress Bar: " . $progressBar);
error_log("APY: " . $compoundInterestAnnualYield);
```

## Summary

✅ **API Updated** - Now uses list endpoint
✅ **BTC Product** - Automatically found by assetCode
✅ **Progress Bar** - Converted to percentage (0.4178 → 41.78%)
✅ **APY Display** - Shows compound interest rate
✅ **10K Share** - Shows revenue per 10,000
✅ **Fallback** - Default values if API fails

All data is now dynamically fetched from the list API and properly displayed in the dashboard! 🎉
