# HALOWERK laufwerk – Vehicle Routing Weight Readiness Check

> HALOWERK laufwerk – Vehicle Routing Weight Readiness Check is a paid API for AI agents from lauf.halowerk.com, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-10).

Checks whether delivery jobs can be feasibly assigned to vehicles given weight capacity and time-window constraints, returning a weight-readiness assessment for a fleet routing problem.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 halowerk-laufwerk-vehicle-routing-weight-readiness-check-22ca51bd -d '<json body>'
```

Example prompt: Check whether our 2 delivery vans — Van-A with a 500 kg weight limit and 8-hour shift (0 to 28800 s), and Van-B with 700 kg and same shift — can handle 5 delivery jobs with weights ranging from 50 to 300 kg, time windows between 0 and 14400 s, and a 2x6 travel-duration matrix I'll provide.

## When to prefer this

Use this endpoint when you need a fast pre-check on whether vehicle weight capacities and time windows are compatible with a set of delivery jobs before committing to full route optimization. It is particularly useful as a lightweight feasibility gate in multi-stage logistics pipelines. Choose this over a full VRP solver when you only need weight-readiness validation without full route assignment or sequencing.

## Known failure modes

- Missing required fields (id, point, demand, window, service_s, weight_kg) returns validation error
- Jobs array empty or exceeds 20-item limit returns schema error
- Vehicles array empty or exceeds 4-item limit returns schema error
- Duration matrix dimensions don't match number of points causes computation error
- Null values in duration matrix may indicate unreachable location pairs
- Weight or demand values exceeding maximums (10,000,000 kg / 100,000 demand) rejected
- Time window values exceeding 604800 s (one week) rejected
- Payment failure via x402 returns 402 status with no computation performed

## Output

Returns a JSON response indicating whether the set of delivery jobs is feasible given vehicle weight capacities, time windows, and the travel-duration matrix — typically includes readiness status, constraint violations, or per-vehicle/per-job feasibility signals.
