Setup & Configuration

Add FAL_KEY

# Interactive setup
bash /mnt/skills/user/fal-platform/scripts/setup.sh --add-fal-key

# Set key directly
bash /mnt/skills/user/fal-platform/scripts/setup.sh --add-fal-key "your_key_here"

# Show current config
bash /mnt/skills/user/fal-platform/scripts/setup.sh --show-config

This adds FAL_KEY to your .env file for persistent use.

Model Pricing

Get pricing for any model:

# Single model pricing
bash /mnt/skills/user/fal-platform/scripts/pricing.sh --model "fal-ai/flux/dev"

# Multiple models
bash /mnt/skills/user/fal-platform/scripts/pricing.sh --model "fal-ai/flux/dev,fal-ai/kling-video/v2.1/pro"

# All pricing for a category
bash /mnt/skills/user/fal-platform/scripts/pricing.sh --category "text-to-image"

Output:

# Current period usage
bash /mnt/skills/user/fal-platform/scripts/usage.sh

# Filter by model
bash /mnt/skills/user/fal-platform/scripts/usage.sh --model "fal-ai/flux/dev"

# Date range

# Estimate by API calls (historical pricing)
bash /mnt/skills/user/fal-platform/scripts/estimate-cost.sh \
  --model "fal-ai/flux/dev" \
  --calls 100

# Estimate by units
bash /mnt/skills/user/fal-platform/scripts/estimate-cost.sh \
  --model "fal-ai/kling-video/v2.1/pro" \
  --units 60 \
