Shipping & Logistics Calc — Container Load Calculator
x402
Shipping & Logistics Calc — Container Load Calculator 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 how many cartons fit in a 20GP, 40GP, or 40HC shipping container using grid packing and payload limits, returning CBM used and the limiting factor.

How this service works
Cartons per 20GP, 40GP or 40HC container by grid packing and payload limit, with CBM used and what limits the load.
Output
Returns the number of cartons loaded, how many were limited by volume versus payload, CBM used and interior CBM, payload used and limit in kg, volume utilization percent, a plain-English summary and verdict, and an explanation of what factor (volume or weight) limited the load. Also includes the container type used and any caveats or not-checked items.
Example use cases
Checking if one container suffices
“I'm shipping 500 cartons that are 55 cm x 45 cm x 35 cm and weigh 15 kg each — will they all fit in a single 40HC container, and will I hit the payload limit or run out of space first?”
Comparing 20GP vs 40HC capacity
“How many of my cartons (50 cm long, 40 cm wide, 25 cm tall, 8 kg each) fit in a 20GP versus a 40HC container? I need to decide which container size to book.”
Freight planning with upright-only cartons
“My cartons must be kept upright — they're 48 cm x 32 cm x 60 cm and weigh 20 kg each. How many can I load into a 40GP container, and what percentage of the container volume will I use?”
Technical details
Endpoint
GEThttps://shipping-calc.x402tookit.com/container-load?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to calculate how many identical cartons fit inside a full shipping container (20GP, 40GP, or 40HC) using grid packing logic that also accounts for gross weight payload limits. It is distinct from box-in-box fitting calculators (which pack boxes inside other boxes) and pallet calculators (which stack cartons on pallets). Choose this when planning FCL (full container load) shipments and needing to know whether volume or payload is the bottleneck.
Side effects
- Missing required dimensions (length, width, height) returns a validation error
- Invalid container type string returns an error or uses default 40HC
- Non-positive or zero dimension values may cause computation errors
- Extremely small carton dimensions relative to container may produce unexpectedly high counts
- If cartonWeightKg is not provided, payload limit check is skipped and notChecked will include payload
- Unit mismatch (e.g. mixing inches and cm) if unit param is wrong will produce incorrect results
