Price Analysis for 64GB Volume:

Portal shows: €5.95 for 64GB = €0.092969 per GB per month

API shows: monthlyPrice = €1.7699999976

Testing different interpretations of API price:

Interpretation	Calculation	Result for 64GB	Match Portal?
Per GB per month	1.7699999976 × 64	€113.28	❌ Too high
Per TB per month	(1.7699999976 ÷ 1000) × 64	€0.11	❌ Too low
Per GB per hour	1.7699999976 × 64 × 720	€81,561.60	❌ Way too high
Flat monthly rate	1.7699999976	€1.77	❌
Find divisor	1.7699999976 ÷ 0.092969	Divisor: 19.04	-
Base allocation	1.7699999976 ÷ 0.092969	~19 GB base	-

Reverse Engineering:

If portal shows €5.95 for 64GB and API shows €1.7699999976, then:

API price ÷ Portal price = 0.30
This suggests API price might be for ~19 GB

Suggested Fix for Your Module:

Based on the analysis, the API's monthlyPrice field appears to be incorrectly interpreted. The actual calculation should be:

// In your getvolumeprice() function:
// The API price seems to be for a different unit or scale
// You need to determine the correct divisor or multiplier

// Option 1: If API price is for a base unit (e.g., 19-20 GB)
$pricePerGB = $valldata->price / 19.04; // Approximate divisor
$monthlyprice = $pricePerGB * $volume;

// Option 2: Use a fixed price mapping
$fixedPrices = [
    'storage_premium_perf0' => ['Single AZ' => 0.093, 'Metro' => 0.234],
    // ... other classes
];
