How this service works
Calculates volume, girth and chargeable weight from package dimensions. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.
Output
Returns computed volume (cm³), girth (cm), volumetric weight (kg), and chargeable weight (kg) along with the derivation method used for each derived value. Any field that cannot be calculated from the supplied inputs is returned as null and listed in the unavailable_fields array, ensuring transparent handling of missing data.
Example use cases
Air freight chargeable weight check
“I need to ship a box that's 60 cm long, 45 cm wide, and 35 cm high with an actual weight of 8 kg. The airline uses a divisor of 6000 — what's the chargeable weight?”
E-commerce courier cost estimation
“My parcel is 25 cm × 20 cm × 15 cm and weighs 1.1 kg. The courier uses a 5000 cm³/kg divisor. Can you calculate the volumetric weight and tell me which weight I'll be billed on?”
Pallet shipment girth and volume calculation
“Calculate the volume and girth for a crate that's 120 cm long, 80 cm wide, and 100 cm tall — I don't have the actual weight yet, just need the dimensional figures for my freight quote.”
Technical details
Endpoint
POSThttps://fracht.halowerk.com/v1/package-dimsWhen to prefer
Use this endpoint when you need a transparent, methodology-disclosed calculation of package chargeable weight and volume directly from raw centimeter dimensions and kilogram weight, especially in freight or logistics workflows where auditability of derived values matters. Prefer it over manual calculation or general-purpose tools when you need consistent handling of missing fields (null + unavailable_fields pattern) and a clear disclosure of whether values were derived or source-backed.
Side effects
- Missing required dimensions (width, height, or length) causes those outputs to be null and listed in unavailable_fields
- Values below minimum threshold (0.01 cm) or above maximum are rejected with a validation error
- Omitting actual_weight_kg means chargeable weight cannot be determined and is returned as null
- Invalid volumetric_divisor_cm3_per_kg (less than 1) causes a validation error
- Non-numeric input values cause a schema validation failure
