# HALOWERK laufwerk — Energy Readiness Tour Optimizer

> HALOWERK laufwerk — Energy 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 2026-10-10).

Checks whether electric vehicles have sufficient energy to complete a set of tours/jobs given travel durations, energy consumption estimates, and vehicle battery constraints

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-energy-readiness-tour-optimizer-08792c80 -d '<json body>'
```

Example prompt: Check if our 2 electric vans — Van A with 45,000 Wh available and 5,000 Wh reserve, Van B with 38,000 Wh available and 4,000 Wh reserve, each with a shift from 0 to 28800 seconds — have enough energy to complete these 5 delivery jobs given the travel durations and energy consumption matrix I'll provide.

## When to prefer this

Use this endpoint when you need to validate battery/energy feasibility for a fleet of electric vehicles before committing to a routing plan. It is specifically designed for the energy dimension of EV tour planning — not general route optimization. Prefer this over generic routing APIs when energy constraints (available charge, reserve thresholds) are a critical dispatch concern. Best suited for fleets of up to 4 vehicles and 20 jobs where you already have a duration matrix and energy consumption estimates.

## Known failure modes

- Invalid matrix dimensions — energy or duration matrix size must match number of jobs and vehicles
- Job or vehicle count exceeds allowed limits (max 20 jobs, max 4 vehicles)
- Time window or shift values out of range (must be 0–604800 seconds)
- Energy values exceed maximum allowed (10,000,000 Wh)
- Missing required fields (id, point, demand, service_s, window for jobs; id, capacity, shift, available_energy_wh, reserve_energy_wh for vehicles)
- Payment failure via x402 — insufficient USDC balance on Base Mainnet
- Null values in energy or duration matrix causing computation gaps

## Output

A JSON response indicating whether the vehicles have sufficient energy to complete the specified tours, likely including per-vehicle or per-job energy feasibility flags, energy balances, and any infeasibility details.
