## 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 clonecho-builda-company-reverse-geocode-53e2fc6c -d '<json body>'
```

Example prompt: What's the street address at coordinates 48.8584° N, 2.2945° E? Give me the full address and any place details you can find.

## When to prefer this

Use this endpoint when you have a geographic coordinate (latitude/longitude) and need a human-readable address or place metadata. It is powered by OpenStreetMap, making it suitable for global coverage at low cost ($0.01 per call). Prefer this over forward geocoding endpoints when you already have coordinates from a GPS device, map click, or sensor and need to display or log a street address.

## Known failure modes

- Coordinates out of range or malformed — returns error or empty result
- Location is in a remote area with no OSM address data — returns sparse or null address fields
- Missing lat or lon query parameter — likely returns 400 or error JSON
- OpenStreetMap Nominatim service unavailable — upstream failure
- Ocean or unpopulated coordinate — may return nearest coastline or null

## How this service works

GEO: reverse geocode a coordinate (?lat=&lon=) to the nearest address + place metadata (OpenStreetMap). Returns JSON.

## Output

A JSON object containing the nearest street address and place metadata for the given coordinates, including fields like street name, house number, city, postcode, country, and place display name — sourced from OpenStreetMap data.
