Geo intelligence

Location, ASN, network, and organization fields merged into one structured JSON response per IP.

Core features

Everything you need for IP intelligence.

From single lookups to bulk pagination — one API for location, ASN, organization, and hosting detection.

Single lookup

GET or POST /api/v1/lookup for one IP — city, region, country, coordinates, and timezone.

Multi-IP batch

Look up up to 100 IPs per request with a JSON array body — same order in, same order out.

Bulk pagination

POST /api/v1/lookup/bulk for large lists with server-side paging up to 1,000 results per page.

ASN data

Autonomous system number, name, and domain for every resolved IP.

Hosting detection

Network signals including is_hosting and IPv4/IPv6 allocation counts.

Geo reference

Extended city, state, and country reference data when available for a match.
