Tools as reported by the server

• dim_weight
  Work out whether a parcel bills on its size or its weight. FREE. Carriers charge the greater of actual weight and dimensional weight, so a light bulky box costs more than the scale suggests. Typical input {"length": 18, "width": 12, "height": 10, "actual_weight": 6} returns {"cubic": 2160.0, "dim_we
• parcel_fit
  Pick the smallest box an item actually fits in, allowing for padding. FREE. Tries every rotation of the item against every box, so an item that only fits diagonally-oriented is still found. Typical input {"item_length": 10, "item_width": 6, "item_height": 4, "box_options": [[12, 9, 4], [14, 10, 6]]}
• landed_cost
  Total what a unit really costs once freight, duty and fees are in. FREE. Duty is applied to goods value, tax to goods plus duty plus freight — the common import treatment — and the order is spelled out in the response so you can check it against your own broker's method. Typical input {"unit_cost":
• freight_class
  Derive a US LTL freight class from density. FREE. Density in pounds per cubic foot maps to a class on the published NMFC density scale. Typical input {"length": 48, "width": 40, "height": 36, "weight": 400} returns {"cubic_feet": 40.0, "density_pcf": 10.0, "density_class": "100", "caveat": "..."}. U
• rate_card
  Turn a cost model into a customer-facing weight-banded price table. PREMIUM (license). Prices each band at its upper bound so you never under-charge inside a band, then rounds up to a tidy increment. Typical input {"base_cost": 4.2, "cost_per_lb": 0.65, "bands_lb": [1, 2, 5, 10], "margin_pct": 25} r
• free_shipping_threshold
  Find the order value at which free shipping stops costing you money. PREMIUM (license). Break-even is where the gross margin on the order covers the shipping you absorb. Typical input {"gross_margin_pct": 45, "ship_cost": 7.5, "current_aov": 38, "target_uplift_pct": 15} returns {"break_even": 16.67,
