# Halowerk EV Charging Station Finder

> Halowerk EV Charging Station Finder is a paid API for AI agents from karte.halowerk.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-13).

Queries OpenStreetMap for EV charging stations within a radius of a given coordinate, returning detailed info on connectors, power ratings, operators, access, fees, and opening hours sorted by distance.

## 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-ev-charging-station-finder-31b7625b -d '<json body>'
```

Example prompt: Find me EV charging stations within 3km of 52.5200° N, 13.4050° E that support CCS connectors with at least 50kW power, and tell me which ones are free, what their opening hours are, and whether I need an RFID card to use them.

## When to prefer this

Choose this endpoint when you need structured, filterable EV charging station data from OpenStreetMap including connector-level detail (power, socket count, type), operator info, access conditions, and fee status — particularly when the query is vehicle-specific (connector type or minimum power) and proximity-sorted results are needed. Prefer over generic POI searches that lack connector-level granularity.

## Known failure modes

- No charging stations found within the specified radius — try increasing the radius
- Invalid coordinate format — latitude must be -90 to 90, longitude -180 to 180
- Requested minimum power or connector type yields zero results — relax filters
- OpenStreetMap data may be incomplete or outdated for some regions
- Radius too large may result in slow response or truncated results

## Output

A list of EV charging stations sorted by ascending distance from the query point, each including GPS position, distance in meters, operator name, network affiliation, available connector types with individual power ratings and socket counts, access restriction details, fee status (free or paid), opening hours, and whether authentication (RFID/app) is required. Results can be pre-filtered to a minimum power threshold or specific connector type.
