# Reverse Geocode Coordinates to Street Address (OpenStreetMap + NWS)

> Reverse Geocode Coordinates to Street Address (OpenStreetMap + NWS) is a paid API for AI agents from webtools402.176-109-107-191.sslip.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Converts latitude/longitude coordinates to a full street address with parsed components worldwide, enriched with nearest NWS city/state for US locations.

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 reverse-geocode-coordinates-to-street-address-openstreetmap-nws-3efc6e20
```

Example prompt: What's the street address at coordinates 40.7128° N, 74.0060° W? I need the full parsed address including city and state.

## When to prefer this

Use this endpoint when you need to resolve raw GPS coordinates to a human-readable street address anywhere in the world, especially when you also want US NWS city/state context alongside the full parsed address components from OpenStreetMap. Prefer over forward-geocoding endpoints when you already have lat/lon and need the address, not the reverse.

## Known failure modes

- Missing lat or lon parameter returns a validation error
- Coordinates out of range (lat outside [-90,90] or lon outside [-180,180]) return an error
- Remote ocean or uninhabited coordinates may return sparse or no address
- Nominatim service unavailability returns a 5xx error
- NWS enrichment may be absent for US coordinates in very remote areas

## How this service works

Reverse-geocode coordinates (WORLDWIDE) to a street address + parsed components via OpenStreetMap Nominatim; enriched with the nearest NWS city/state when the point is in the US.

## Output

A full street address with parsed components (street, city, state, postal code, country) derived from OpenStreetMap Nominatim; for US coordinates, additionally includes the nearest NWS city and state name.
