IP-API Has a Free API — Get Geolocation for Any IP Address Without an API Key

Every app that deals with users eventually needs to know where they are. Whether you’re personalizing content, blocking suspicious traffic, or logging analytics — IP geolocation is essential.

Most geolocation APIs require signup, API keys, and credit cards. IP-API gives you all of this for free — no key, no signup, no limits for non-commercial use.

What You Get

One HTTP request returns:

• Country, region, city, zip code
• Latitude and longitude
• Timezone
• ISP name and organization
• AS number

Try It Right Now

curl http://ip-api.com/json/8.8.8.8

Response:

{
  "status": "success",
  "country": "United States",
  "regionName": "Virginia",
  "city": "Ashburn",
  "lat": 39.03,
  "lon": -77.5,
  "timezone": "America/New_York",
  "isp": "Google LLC",
  "org": "Google Public DNS",
  "query": "8.8.8.8"
}

That’s Google’s public DNS server — located in Ashburn, Virginia.

Python Example: Geolocate Any IP

import requests

def geolocate(ip):
    response = requests.get(f"http://ip-api.com/json/{ip}")
    data = response.json()
    if data["status"] == "success":
        return {
            "ip": ip,
            "location": f"{data['city']}, {data['regionName']}, {data['country']}",
            "coordinates": f"{data['lat']}, {data['lon']}",
            "isp": data["isp"],
            "timezone": data["timezone"]
        }
    return {"error": data.get("message", "Unknown error")}

# Try it
result = geolocate("1.1.1.1")
print(result)
# {'ip': '1.1.1.1', 'location': 'Los Angeles, California, United States', ...}

JavaScript (Node.js) Example

async function geolocate(ip) {
  const res = await fetch(`http://ip-api.com/json/${ip}`);
  const data = await res.json();

  if (data.status === "success") {
    console.log(`${ip} is in ${data.city}, ${data.country}`);
    console.log(`ISP: ${data.isp}`);
    console.log(`Coordinates: ${data.lat}, ${data.lon}`);
  }
}

geolocate("8.8.8.8");
// 8.8.8.8 is in Ashburn, United States
// ISP: Google LLC
// Coordinates: 39.03, -77.5

Batch Lookup (Up to 100 IPs)

Need to check multiple IPs at once? IP-API supports batch requests:

import requests

ips = ["8.8.8.8", "1.1.1.1", "208.67.222.222"]
response = requests.post(
    "http://ip-api.com/batch",
    json=ips
)

for result in response.json():
    print(f"{result['query']}: {result['city']}, {result['country']} ({result['isp']})")

# 8.8.8.8: Ashburn, United States (Google LLC)
# 1.1.1.1: Los Angeles, United States (Cloudflare, Inc.)
# 208.67.222.222: San Francisco, United States (Cisco OpenDNS, LLC)

Real-World Use Cases

1. Security monitoring — A startup I worked with used IP-API to flag login attempts from unexpected countries. If a user usually logs in from Germany but suddenly appears from Nigeria, that’s a red flag.

2. Content personalization — Show currency, language, or shipping options based on visitor location without asking them.

3. Analytics dashboards — Map your API traffic geographically. Know which regions use your service most.

4. Fraud detection — Cross-reference IP geolocation with billing address. Mismatches often indicate fraud.

Rate Limits & Pro Plan

For development, testing, and personal projects — the free tier is more than enough.

Compared to Alternatives

IP-API wins on simplicity: no signup, no key, just curl and go.

Quick Tips

1. Use fields parameter to get only what you need:

curl "http://ip-api.com/json/8.8.8.8?fields=country,city,lat,lon"

1. Check your own IP:

curl http://ip-api.com/json/

1. Get CSV format for scripts:

curl http://ip-api.com/csv/8.8.8.8

Need to process thousands of IPs for security research or analytics? I’ve built production-grade data extraction tools that handle IP enrichment at scale — no rate limits, no bans.
