Country Borders

Overview

Pass a two-letter ISO country code to retrieve all neighboring countries sharing a land boundary. Responses detail the nation's full name, geographic region, subregion, and whether it is landlocked. Paid plans add geographic center coordinates for the requested country.

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.

package main

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

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/countryborders?country=CA", 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.

Parameters

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

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.

{
  "status": "ok",
  "error": null,
  "data": {
    "country": "Canada",
    "cca2": "CA",
    "landlocked": false,
    "region": "Americas",
    "subregion": "Northern America",
    "coordinates": {
      "lat": 60,
      "lng": -95
    },
    "borders": [
      "USA"
    ]
  }
}

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.

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.

Use cases

Cross-Border Route Planning

Freight dispatchers check adjacent nations along transport corridors to verify transit jurisdictions and identify landlocked destinations needing sea-port rerouting.

Regional Market Expansion

E-commerce platforms identify neighboring territories around existing warehouses to sequence regional delivery coverage country by country.

Geopolitical Strategy Games

Game developers build realistic adjacency maps between territories to enforce valid troop movements across shared national borders.

Compliance Risk Screening

When auditing vendor supply chains, trade compliance officers flag suppliers operating adjacent to sanctioned territories.
