Pricing

Returns unit pricing for requested endpoint IDs. Most models use output-based pricing (e.g., per image/video with proportional adjustments for resolution/length). Some models use GPU-based pricing depending on architecture. Values are expressed per model’s billing unit in a given currency.

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

Common Use Cases:

Display pricing in user interfaces
Compare pricing across different models
Build cost estimation tools
Check current billing rates

See fal.ai pricing for more details.

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 See [fal.ai pricing](https://fal.ai/pricing) for more details.
