Estimate cost

Computes cost estimates using one of two methods:

1. Historical API Price (historical_api_price):

• Based on historical pricing per API call from past usage patterns
• Takes call_quantity (number of API calls) per endpoint
• Useful for estimating based on actual historical usage patterns
• Example: "How much will 100 calls to flux/dev cost?"

2. Unit Price (unit_price):

• Based on unit price × expected billing units from pricing service
• Takes unit_quantity (number of billing units like images/videos) per endpoint
• Useful when you know the expected output quantity
• Example: "How much will 50 images from flux/dev cost?"

Authentication: Required. Users must provide a valid API key. Custom pricing or discounts may be applied based on account status.

Common Use Cases:

• Pre-calculate costs for batch operations
• Display cost estimates in user interfaces
• Budget planning and cost optimization
