How this service works
HALOWERK kartenwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns a list of barrier objects (gates, bollards, lift gates, cycle barriers) with each barrier's type, geographic position, distance from the destination, and whether it is locked. Also returns ways (road segments) with their access restriction tags and the group they apply to, and flags any physical limits (max height, weight, width, length) that conflict with the vehicle dimensions supplied.
Example use cases
Delivery van last-mile clearance check
“I need to deliver to a warehouse at 51.4923, -0.1927 with a van that's 2.8m tall, 2.1m wide, and 3.5 tonnes — can you check whether there are any bollards, locked gates, height bars, or weight-restricted roads blocking access to it?”
Camping trip vehicle access check
“We're driving a 4m tall motorhome to a campsite at 47.6741, 11.8601 — before we set off, can you check if there are any lift gates, barrier arms, or height or weight restrictions on the roads leading to it?”
Emergency services route barrier audit
“I need to know if an ambulance — 2.4m wide, 3.0m tall, 5 tonnes — can reach the entrance at 48.8566, 2.3522 without hitting any locked barriers or access-restricted roads. Flag anything that would stop it.”
Technical details
Endpoint
POSThttps://karte.halowerk.com/v1/last-mile-access?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to know whether a specific vehicle with known dimensions can physically reach a destination — especially for last-mile logistics, delivery route planning, or accessibility audits. It is distinct from general routing APIs because it focuses on physical and access barriers in the immediate vicinity of a destination rather than turn-by-turn directions, and it returns dimension-specific verdicts rather than generic warnings.
Side effects
- Coordinate outside OpenStreetMap coverage returns empty or sparse results
- Missing or out-of-date OSM data for barriers in rural or newly mapped areas
- Vehicle dimensions not supplied may result in generic rather than vehicle-specific responses
- Unlocked or removable barriers may not be flagged as blocking depending on OSM tagging quality
- Network timeout or service unavailability returns an error response
