# HALOWERK laufwerk — Quiet Hours Readiness Tour Optimizer

> HALOWERK laufwerk — Quiet Hours Readiness Tour Optimizer is a paid API for AI agents from lauf.halowerk.com, paid per call via x402, $0.007/call, status unknown (last checked 2026-10-22).

Solves a vehicle routing problem with quiet-hours constraints, scheduling jobs to vehicles while respecting noise restriction windows and time windows.

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-quiet-hours-readiness-tour-optimizer-18971bff -d '<json body>'
```

Example prompt: Plan delivery routes for 3 vehicles (each with 500kg capacity, working 8am–6pm Monday) across 10 job stops — each job has a demand, a service time, a time window, and noise restriction periods like no visits between midnight–6am and 10pm–midnight. Use the provided travel duration matrix.

## When to prefer this

Choose this endpoint when you need to solve a vehicle routing problem that explicitly incorporates quiet-hour constraints (e.g. noise ordinances, residential restrictions) in addition to standard time windows and capacity limits. It is ideal for urban last-mile logistics, field service scheduling, or waste collection where regulatory or contractual noise bans must be respected. Prefer it over generic VRP solvers when quiet-hours compliance is a hard constraint, not just a soft preference.

## Known failure modes

- No feasible solution found if quiet hours and time windows make all assignments infeasible
- Validation error if required fields (id, point, demand, service_s, window, quiet_hours) are missing from any job
- Validation error if vehicles array is empty or missing required fields
- Matrix dimension mismatch if durations_s does not match the number of jobs plus depot
- Exceeding item limits (more than 20 jobs or 4 vehicles) triggers a schema validation error
- Null entries in durations_s may cause routing failures if critical arcs are missing
- Payment failure if x402 USDC payment on Base Mainnet is not completed

## Output

A JSON response containing the optimized assignment of jobs to vehicles, including the sequence of stops per vehicle, scheduled arrival/departure times, and overall routing metrics — all respecting the specified quiet-hour windows, time windows, and vehicle capacity constraints.
