handel.halowerk.com
Loads a package list into one loading space and returns the plan, not an estimate. The floor starts as one free surface; packages are sorted by footprint, then height, then weight, then identifier, and each one is placed on the lowest, then frontmost, then smallest free surface it fits on, turned by 90 degrees around the vertical axis where that makes it fit.

Provider
The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

"description": "Loads a package list into one loading space and returns the plan, not an estimate. The floor starts as one free surface; packages are sorted by footprint, then height, then weight, then identifier, and each one is placed on the lowest, then frontmost, then smallest free surface it fits on, turned by 90 degrees around the vertical axis where that makes it fit. Every placement splits the surface it used into two remainders and, where the package may be stacked on, opens a new free surface on top of it at its own height, so the floor is filled before anything is stacked and a stack is only ever built where the floor has run out. Packages are never tipped, so the stated height stays the height. Every placement comes back with its x, y and z coordinate in millimetres, its orientation, its stack level and the package it rests on, which makes the plan checkable rather than merely plausible. Three limits are enforced and every rejection names the limit it hit: loading stops before max_payload_kg is exceeded, no surface is opened on a package marked stackable false, and max_stack_load_kg is checked against the whole chain of packages underneath before a placement is made, so it constrains the plan rather than warning about it afterwards; the same check is run again over the finished plan and its result is reported. The result gives volume and floor-area utilization, payload utilization, the highest stack level, the centre of gravity in all three axes and, when two axle groups are given, the static payload share on each of them by the lever rule, flagged when it exceeds max_load_kg or when the centre of gravity falls outside the axle span. Every ordering is decided by the input, so the same request always returns the same plan; it is a good load, not a proven optimum, because three-dimensional packing is NP-hard, and a guillotine split cannot reuse an L-shaped remainder, which is stated in the response rather than hidden. This is not load securing: lashing forces, friction coefficients and VDI 2700 are out of scope, and so is any dynamic axle load.",

Using Roundhouse, look up the x402 service handel.halowerk.com and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=handel.halowerk.com' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://handel.halowerk.com/v1/container-load, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
