What does the IP to Company API return?

For each IP address you submit, the API returns: the associated company domain (e.g. google.com), the registered organization name, country, region, city, ISP, and timezone. If no domain is associated with the IP, the lookup returns empty data and no credits are charged.

When are credits charged?

Credits are only charged when a domain is successfully resolved — 100 credits per IP. If the IP is a residential connection, mobile network, or unknown host with no associated company domain, the lookup costs zero credits.

How do I use this for website visitor identification?

Capture the visitor's IP from your server logs or a first-party script. Pass it to the IP to Company API and get the company domain and organization name back. Use that to route the visitor, trigger a sales alert, or personalize their experience in real time.

Does it work for all IP types?

The API resolves IPs registered to companies, cloud providers, universities, and other organizations. Residential ISP addresses, mobile carrier IPs, and VPN exit nodes typically do not resolve to a company domain and are not charged.

Send an IP address and get back the associated company domain, organization name, location (country, region, city), ISP, and timezone.

Features

Company Domain Resolution

Resolves an IP address to the company domain associated with it — the core output most use cases need.

Organization Name

Returns the registered organization name behind the IP, useful when the domain alone isn't enough context.

Location Data

Returns country, region, and city for the IP address for geographic segmentation and routing.

ISP Detection

Identifies the Internet Service Provider, helping you distinguish corporate IPs from residential or mobile connections.

Timezone

Returns the timezone for the IP location, useful for scheduling follow-ups and personalizing outreach timing.

No Charge on Miss

Credits are only consumed when a domain is successfully resolved. If no domain is found, the lookup is free.
