## Tools (as reported by the server, not verified)

- `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,
