# HALOWERK laufwerk — Temperature-Constrained Delivery Tour Readiness Check

> HALOWERK laufwerk — Temperature-Constrained Delivery Tour 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).

Validates whether vehicles with specific temperature ranges are compatible with temperature-sensitive delivery jobs before routing, returning a readiness assessment for cold-chain and temperature-controlled logistics.

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-temperature-constrained-delivery-tour-readiness-check-7ad6caa2 -d '<json body>'
```

Example prompt: Check if my 2 refrigerated trucks (each holding 0°C to 5°C, capacity 5000kg, shifts 8am–6pm) can handle today's 5 grocery delivery stops — each requiring 2°C to 4°C, with demands between 200–800kg and time windows spread across the day — using this travel duration matrix I have ready.

## When to prefer this

Use this endpoint before running full vehicle routing optimization when your fleet and delivery jobs involve temperature-sensitive cargo — it lets you quickly screen for temperature incompatibilities and save compute on infeasible routing problems. Prefer it over a full VRP solver when you only need to know if your vehicles can physically handle the jobs from a temperature standpoint, not yet the optimal routes.

## Known failure modes

- Invalid temperature range (min > max) in job or vehicle specification
- Job or vehicle array outside allowed size limits (jobs 1–20, vehicles 1–4)
- Duration matrix dimensions don't match number of jobs plus depot
- Time window values exceed 604800 seconds (one week)
- Missing required fields such as id, point, demand, window, service_s, or temperature_c
- Payment failure via x402 protocol (402 response if USDC payment not included)

## Output

A JSON response indicating temperature readiness status for the provided job-vehicle combinations — flagging which jobs are compatible or incompatible with the available vehicles' temperature profiles, shift windows, capacity constraints, and time windows before full route optimization is attempted.
