## 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-halowerk-com-public-toilets-finder-4ad57b67 -d '<json body>'
```

Example prompt: Find public toilets within 400 meters of 52.5200° N, 13.4050° E and tell me which ones are free, wheelchair accessible, and have baby changing tables.

## When to prefer this

Use this endpoint when you need structured, filterable public toilet data near a specific coordinate — especially when accessibility, baby facilities, cost, or opening hours are decision factors. Prefer this over general POI search APIs when the specific metadata fields (wheelchair, fee, baby changing, drinking water, operator) are needed for routing or filtering logic.

## Known failure modes

- No toilets found within the specified radius — empty result set returned
- Invalid or out-of-range coordinates causing a request error
- Radius too large causing timeout or excessive results
- OpenStreetMap data may be incomplete or outdated for a given area
- Missing or null fields for toilets where OSM tags are absent

## How this service works

Returns public toilets within a radius of a coordinate, sorted by distance, each with what decides whether it is usable: whether a fee applies and how much, the opening hours in raw OpenStreetMap syntax, wheelchair accessibility, whether a baby changing table is present, whether it is unisex or separated, whether drinking water is available, and the operator.

## Output

A list of public toilet locations sorted by distance from the query coordinate, each containing: geographic position, distance, fee status and amount, raw OpenStreetMap opening hours, wheelchair accessibility flag, baby changing table presence, gender separation type (unisex or separated), drinking water availability, and operator name.
