HALOWERK laufwerk — Carbon-Constrained VRP Readiness
x402
HALOWERK laufwerk — Carbon-Constrained VRP Readiness 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).
Checks whether a vehicle routing problem (VRP) can be solved within a specified CO2 emissions budget, returning carbon readiness status and route feasibility data.

How this service works
HALOWERK laufwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
A JSON response indicating whether the routing problem is feasible within the specified CO2 emissions budget, likely including the computed total CO2 emissions, whether the carbon constraint is satisfied (carbon readiness status), and potentially route assignments or infeasibility details if the constraint cannot be met.
Example use cases
Last-mile CO2 budget compliance check
“I need to verify that my 4 delivery vans can service all 15 drop-off points in the city today without exceeding our 80,000 gram CO2 budget. Each van has different emission rates and capacities, and all jobs have time windows. Can you check if the routing plan is carbon-ready using the distance matrix from our mapping system?”
Green logistics fleet sizing validation
“We're pitching a carbon-neutral delivery service to a client and need to confirm that 2 electric vehicles (5 g CO2/km each) and 1 diesel backup (220 g CO2/km) can cover 12 customer jobs within a 40,000 gram CO2 cap. Can you run a carbon readiness check with our time windows and route distances?”
Sustainability compliance pre-check before dispatch
“Before we dispatch our trucks this morning, check if our planned routes across 20 stops with 4 vehicles stay under the 60,000 gram CO2 threshold we've committed to in our ESG report — here are the job locations, service times, vehicle shift hours, and the distance and duration matrices.”
Technical details
Endpoint
POSThttps://lauf.halowerk.com/v1/tours/carbon-readiness?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate a vehicle routing plan against a hard CO2 emissions constraint before dispatching — particularly useful for sustainability-reporting logistics, green delivery services, or any fleet operation with carbon budget commitments. Prefer this over generic VRP solvers when the carbon readiness dimension is a primary constraint, not just an afterthought. Best suited for small-to-medium routing problems (up to 20 jobs, 4 vehicles) where you already have a distance/duration matrix from an external mapping provider.
Side effects
- Invalid or missing distance/duration matrix dimensions not matching the number of jobs and vehicles
- Job or vehicle count exceeding allowed maximums (20 jobs, 4 vehicles)
- Time window values outside 0–604800 second range
- Null values in distance/duration matrix causing route infeasibility
- max_co2e_grams set to zero or unrealistically low, always returning infeasible
- Demand values exceeding vehicle capacity for all vehicles, causing infeasibility
- Missing required fields (id, point, demand, window, service_s for jobs; id, capacity, shift, grams_co2e_per_km for vehicles)
- Payment failure via x402 protocol resulting in 402 status and no computation
