# Lookup US Address by Coordinates API

Convert latitude and longitude into address data. Built for maps, delivery events, and turning raw coordinates into usable address context.

#### Quickstart

Look up an address by latitude and longitude.

  },

## About

## What it does
Reverse Address Lookup turns latitude and longitude into a location lookup result. Send `lat` and `lon` as query parameters, and get back the address data the service can resolve for that point.

Use it when you already have coordinates from a map click, GPS trace, delivery event, or analytics record and need to attach a human-readable location. It fits workflows like marking customer check-ins, enriching trip logs, or converting geospatial events into something your support or operations team can read.

The endpoint is simple on purpose: it only requires `lat` and `lon`, with valid ranges of -90 to 90 for latitude and -180 to 180 for longitude. 

If your application stores coordinates but needs address context for search, display, reporting, or downstream validation, Reverse Address Lookup gives you the conversion step without extra geocoding logic in your own code.
