// Geolocate any IP — replace with your API key const response = await fetch( 'https://api-bdc.net/data/ip-geolocation ?ip=1.1.1.1&key=YOUR_KEY'); const data = await response.json(); console.log(data.location.city); // "Sydney" console.log(data.confidence); // "high"
Flexible Data Retrieval
REST or GraphQL. Your choice.
The only IP geolocation provider offering GraphQL. Request exactly the fields you need — nothing more, nothing less.
GET /data/ip-geolocation?ip=1.1.1.1&key=YOUR_KEY // Full response object (~2 KB): { "ip": "1.1.1.1", "location": { "city": "Sydney", "countryCode": "AU", "latitude": -33.87, "longitude": 151.21 }, "confidence": "high", "network": { /* isp, asn, prefixes… */ }, "hazardReport": { /* vpn, proxy, tor… */ } // ... 50+ fields }
POST /graphql/ip-geolocation query { ipGeolocation(ip: "1.1.1.1") { location { city countryCode } confidence } } // Response: only what you asked for (~200B) { "location": { "city": "Sydney", "countryCode": "AU" }, "confidence": "high" }
Same data. Same accuracy. Same price. GraphQL just lets you choose what comes back.

The only provider that publishes daily accuracy benchmarks
Every day, we test our geolocation against real GPS ground truth and compare with other providers. The results are public. No marketing claims — just data.
What the report shows
GPS ground truth testing
Accuracy is measured against real device GPS coordinates — not self-reported data.
Head-to-head comparison
Results compared against other major providers using the same methodology.
Country-level breakdown
Accuracy varies by country — the report shows where we perform and where we don't.
Patented technology
Our geolocation method is protected by US Patent 11,792,110.
