## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability import-landed-cost-per-unit-retail-tier-calculator-04140855
```

Example prompt: Calculate my import landed cost and pricing tiers for a shipment of 1,000 units at $4.20 FOB each, with $850 total ocean freight, and a 7.5% combined duty rate — break it down per unit and show me wholesale and DTC price targets.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, formula-based landed cost calculation for US import shipments — especially when you want per-unit cost breakdown across FOB, freight, duty, MPF, HMF, and brokerage with automatic 2x–5x retail pricing tiers. Prefer this over general-purpose calculators when you specifically need US CBP fee components (MPF, HMF) and retail tier guidance in a single call. Not suitable for real-time tariff classification or country-of-origin determination.

## Known failure modes

- Missing required query parameters (fob_unit_usd, units, freight_total_usd, duty_pct) return a 400 error
- Non-numeric string values for numeric fields may cause parsing errors
- Extremely small unit counts (e.g. units=1) may produce unrealistic MPF/HMF allocations
- duty_pct values above 100 or negative values may not be validated and could produce nonsensical results
- Payment not processed (402) if x402 USDC payment header is missing or insufficient

## How this service works

Deterministic import landed cost per unit calculator. Pass ?fob_unit_usd=4.20&units=1000&freight_total_usd=850&duty_pct=7.5. Allocates FOB, ocean/air freight, customs duty, Merchandise Processing Fee (MPF), Harbor Maintenance Fee (HMF), and brokerage across the batch, returning per-unit landed cost and 2x-5x wholesale/DTC price tiers.

## Output

Returns a JSON object with: (1) echoed inputs, (2) batch_totals_usd breaking out total FOB, freight, duty, MPF, HMF, brokerage/local delivery, and total landed batch cost; (3) per_unit_breakdown_usd with each cost component allocated per unit and total per-unit landed cost; (4) target_pricing_tiers with wholesale 2x, DTC 3x, 4x, and 5x price points; plus a timestamp and disclaimer.
