# Karte Last-Mile Access Barrier Check

> Karte Last-Mile Access Barrier Check is a paid API for AI agents from karte.halowerk.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-11).

Analyzes roads, paths, and physical barriers (gates, bollards, lift gates) around a destination to determine whether a specific vehicle can reach it, accounting for access restrictions and physical dimension limits.

## 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 karte-last-mile-access-barrier-check-49237ef0 -d '<json body>'
```

Example prompt: Can my delivery truck — 3.5m tall, 2.4m wide, 7.5 tonnes — actually get to the loading bay at coordinates 52.5163, 13.3777? Check for any barriers, locked gates, bollards, or road restrictions blocking the last mile.

## When to prefer this

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.

## Known failure modes

- 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- Missing or out-of-date OSM data for barriers in rural or newly mapped areas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

## 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.
