## 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 positionstack-reverse-geocoding-45b58f9b
```

Example prompt: What street address or location is at coordinates 48.8566, 2.3522? Give me up to 3 results.

## When to prefer this

Use this endpoint when you have a latitude/longitude pair and need to resolve it to a human-readable address or place name. Ideal for enriching GPS data, geotagged events, or any scenario where coordinates need to be presented as meaningful locations to users.

## Known failure modes

- Invalid coordinate format — query must be 'lat,lon' (e.g. '40.7128,-74.0060')
- Coordinates out of valid range (lat outside -90 to 90, lon outside -180 to 180)
- No address found for remote or ocean coordinates
- Rate limit or payment authorization failure returning 402
- Malformed request missing required query parameter

## How this service works

Reverse geocoding: coordinates -> address.

## Output

Returns structured location data including street address, city, region, country, and postal code corresponding to the provided latitude and longitude coordinates, with up to `limit` results ranked by relevance.
