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
Returns a full street address string plus parsed address components (house number, road, city, state, country, postcode, etc.) from OpenStreetMap Nominatim. For points within the United States, the response is additionally enriched with the nearest National Weather Service (NWS) city and state designation.
Example use cases
Example prompt
“What's the street address for the coordinates 37.7749° N, 122.4194° W? I also want to know the nearest NWS city if it's in the US.”
Technical details
Endpoint
GEThttps://payai.agentstools.dev/geocode/reverseWhen to prefer
Use this endpoint when you have geographic coordinates and need a human-readable street address or location label, especially when worldwide coverage is required (via OpenStreetMap Nominatim) or when US NWS city context is valuable. Prefer over raw Nominatim calls when you want the NWS enrichment bundled in a single paid API call with no quota management.
Side effects
- Coordinates out of valid range (lat outside [-90,90] or lon outside [-180,180]) returns a validation error
- Remote ocean or uninhabited location may return no address or only a country-level result from Nominatim
- Missing required lat or lon query parameters returns a 400-level error
- NWS enrichment is only available for US points; non-US coordinates will not include NWS city/state
- Nominatim rate limiting or upstream outage may cause timeouts or 5xx errors
