Reverse Geocode API Reference

Overview

Reverse Geocode works by converting the latitude and longitude coordinates into a human-readable address. Only supports USA and Canada Coordinates. It uses advanced algorithms and a large database of locations to provide accurate and up-to-date information.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

GEThttps://api.apiverve.com/v1/reversegeocode

curl "https://api.apiverve.com/v1/reversegeocode?lat=40.714224&lon=-73.961452" \
  -H "x-api-key: your_api_key_here"

const res = await fetch('https://api.apiverve.com/v1/reversegeocode?lat=40.714224&lon=-73.961452', {
  headers: { 'x-api-key': 'your_api_key_here' },
});

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

const { data } = await res.json();
console.log(data);

import requests

res = requests.get(
    "https://api.apiverve.com/v1/reversegeocode?lat=40.714224&lon=-73.961452",
    headers={"x-api-key": "your_api_key_here"},
    timeout=15,
)
res.raise_for_status()

print(res.json()["data"])

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/reversegeocode?lat=40.714224&lon=-73.961452", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

Parameter	Type	Description
`lat`Required	number	The latitude of the coordinates range -90–90
`lon`Required	number	The longitude of the coordinates range -180–180

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "zipcode": "11211",
    "state_abbr": "NY",
    "city": "Brooklyn",
    "state": "New York",
    "distance": 0.6501757300758664,
    "latitudeClosest": "40.712090",
    "longitudeClosest": "-73.95427",
    "countryCode": "US",
    "latitude": 40.714224,
    "longitude": -73.961452,
    "estimatedCity": true,
    "nearestCities": [
      "Brooklyn",
      "Brooklyn Park",
      "East Brooklyn",
      "Brooklyn Center",
      "Brooklyn Heights"
    ]
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`zipcode`	string	`"11211"`	ZIP code for the location
`state_abbr`	string	`"NY"`	Two-letter state abbreviation code
`city`	string	`"Brooklyn"`	Primary city name at coordinates
`state`	string	`"New York"`	Full state name
`distance`Premium	number	`0.6501757300758664`	Distance to closest coordinates in miles
`latitudeClosest`Premium	string	`"40.712090"`	Latitude of closest mapped coordinate
`longitudeClosest`Premium	string	`"-73.95427"`	Longitude of closest mapped coordinate
`countryCode`	string	`"US"`	ISO country code for location
`latitude`	number	`40.714224`	Input latitude coordinate
`longitude`	number	`-73.961452`	Input longitude coordinate
`estimatedCity`Premium	boolean	`true`	Whether city is estimated or exact match
`nearestCities`Premium	array	`[Brooklyn, ...]`	List of nearby cities ordered by proximity

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted	A key restriction or IP allow-list; see key scoping.
`429`	Rate limited, or out of credits	Read `error` to tell them apart; see rate limits.

Use cases

Location Services: Use the Reverse Geocode API to get the location of coordinates for location-based services. Use the data to provide users with accurate location information and improve user experience
Geotagging: Geotag photos by using the Reverse Geocode API to get the location of coordinates. Use the data to add location information to images, videos, and social media posts
Mapping Applications: Enhance mapping applications by using the Reverse Geocode API to get the location of coordinates. Use the data to display addresses, landmarks, and points of interest on maps
Emergency Services: Improve emergency services by using the Reverse Geocode API to get the location of coordinates. Use the data to locate callers, dispatch responders, and provide assistance in emergencies

Other ways to use Reverse Geocode

Set up Reverse Geocode on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
