# HALOWERK laufwerk — Shift Reserve Readiness Check

> HALOWERK laufwerk — Shift Reserve 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).

Computes shift-reserve readiness for vehicle routing: checks whether vehicles can complete assigned jobs within their shift windows while maintaining a minimum reserve buffer.

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-shift-reserve-readiness-check-e55194ac -d '<json body>'
```

Example prompt: Check shift-reserve readiness for 2 vehicles (cap 500 each, shifts 0–28800s) covering 3 jobs at points 1, 2, 3 with demands 10, 20, 15 and time windows [0,14400], [3600,18000], [7200,21600], service times 300s each, using the provided 4×4 duration matrix, and a minimum return reserve of 1800 seconds.

## When to prefer this

Use this endpoint when you need to pre-validate whether a set of vehicle shifts can accommodate all assigned jobs — specifically when shift reserve buffers (return time margins) are a hard operational constraint. Prefer this over full VRP solvers when you already have a candidate route assignment and simply need a feasibility/readiness check, or when you want to audit existing schedules before dispatch rather than generate new optimal routes.

## Known failure modes

- Invalid duration matrix dimensions (must match number of jobs + depot points)
- Job time windows that are infeasible given travel durations
- Vehicle capacity exceeded by assigned job demands
- Shift window too short to service any jobs
- Missing required fields (id, point, demand, service_s, window) on jobs or vehicles
- Duration matrix contains nulls on critical path legs
- minimum_return_reserve_s exceeds available shift time

## Output

A JSON response indicating whether the given vehicle-job configuration satisfies shift-reserve readiness constraints — likely including per-vehicle feasibility flags, reserve times remaining, and whether the minimum return reserve threshold is met for each shift.
