Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 webtools402-forward-geocoder-nominatim-d922d9b6
```

Example prompt: Can you get me the latitude and longitude for '1600 Pennsylvania Avenue NW, Washington DC'?

## When to prefer this

Use this endpoint when you need to convert a human-readable address or place name to coordinates without requiring an API key, especially for worldwide coverage at low cost. Prefer this over reverse geocoding endpoints when the input is a text address rather than coordinates.

## Known failure modes

- Address not found or ambiguous — Nominatim returns no results
- Malformed or empty address string — returns error
- Rate limiting from underlying Nominatim public API — slow or failed response
- Non-geographic input (e.g. person names, abstract concepts) returns no match

## How this service works

Forward-geocode a street address or place name (WORLDWIDE) to coordinates + parsed address components via OpenStreetMap Nominatim (public, keyless).

## Output

Returns geographic coordinates (latitude, longitude) and parsed address components (street, city, country, etc.) for the provided address or place name, sourced from OpenStreetMap Nominatim.
