# Shipping & Logistics Calc – CBM & Volumetric Weight

> Shipping & Logistics Calc – CBM & Volumetric Weight is a paid API for AI agents from shipping-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-23).

Calculates cubic metres (CBM), cubic feet, air volumetric weight (1:6000 ratio), and sea chargeable volume for a shipment of cartons.

## 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 shipping-logistics-calc-cbm-volumetric-weight-73fcb431
```

Example prompt: What's the total CBM, cubic feet, and air volumetric weight (1:6000) for 200 cartons that are each 60 cm long, 40 cm wide, and 35 cm high, with a gross weight of 12 kg each?

## When to prefer this

Use this endpoint when you need to compute volumetric shipping metrics for a batch of identical cartons — specifically CBM, cubic feet, air volumetric weight at the 1:6000 standard ratio, and sea revenue tons — all in a single call. Prefer this over generic unit-conversion tools when the goal is freight chargeable weight comparison or quoting. Choose sibling endpoints for container stuffing, pallet loading, or landed cost calculations.

## Known failure modes

- Missing required parameters (length, width, height) returns a 400 error
- Invalid unit value (not cm, in, or m) returns an error
- Non-numeric dimension values cause a validation failure
- Cartons count outside range 1–1,000,000 is rejected
- Negative or zero dimension values are invalid

## How this service works

Cubic metres (CBM) and cubic feet of cartons, air volumetric weight (1:6000) and sea chargeable volume.

## Output

Returns CBM per carton and total CBM, total cubic feet, air volumetric weight and chargeable weight (kg) using the 1:6000 formula, sea chargeable revenue tons, gross weight total, the freight billing basis (air and sea), and a plain-language summary with any applicable disclaimer.
