Karte HaloWerk Emission Zone Lookup
x402
Karte HaloWerk Emission Zone Lookup is a paid API for AI agents from karte.halowerk.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Finds low-emission zones, congestion charge areas, and access-restricted areas near a given coordinate using OpenStreetMap tags, returning each zone's type, vehicle restrictions, operator, distance, and the matching OSM tag.

How this service works
Looks for low-emission zones, congestion charge areas and access-restricted areas around a coordinate and reports each with its type, the vehicle classes it restricts where tagged, the operator, and the distance from your point. Zones are matched by the tags actually used for this in OpenStreetMap, including boundary relations and landuse areas carrying emission tags, and the response lists which tag produced each hit so a questionable match can be judged.
Output
A list of nearby emission zones, congestion charge areas, and access-restricted areas, each including: zone type, distance from the input coordinate, vehicle classes restricted (where tagged), the operator managing the zone, and the specific OpenStreetMap tag that produced the match.
Example use cases
Diesel van delivery route check
“Before dispatching our diesel van to 48.8566° N, 2.3522° E in Paris, can you check within 500 meters whether there are any low-emission or access-restricted zones that would block it, and tell me what vehicle classes are affected?”
EV fleet compliance audit
“We're planning stops for our electric vehicle fleet around 51.5074° N, 0.1278° W in London — can you look for emission zones and congestion charge areas within 2 kilometers and list each zone type, its restrictions, and the managing operator?”
Logistics hub site assessment
“I'm evaluating a new warehouse site at 48.1351° N, 11.5820° E in Munich — can you find any low-emission zones, congestion areas, or vehicle access restrictions within 1 kilometer and tell me which OSM tags identified each one?”
Technical details
Endpoint
POSThttps://karte.halowerk.com/v1/emission-zoneWhen to prefer
Choose this endpoint when you need to determine whether a specific location is subject to emission-based driving restrictions, congestion charges, or vehicle access controls, especially when the source-of-truth tagging from OpenStreetMap is important and you need to understand which specific OSM tag justified each zone match. Preferable over generic geocoding or routing APIs that don't surface environmental zone metadata.
Side effects
- No zones found within the specified radius — empty result set returned
- Coordinate outside OSM coverage or sparsely mapped area — results may be incomplete
- Ambiguous OSM tags may produce questionable matches — each result includes the tag for manual review
- Invalid coordinate format or out-of-range values — request error
- Radius too large causing timeout or oversized response
