IPs and Domains

With an active paid subscription, you can whitelist your server's public IP address or your website's domain to authenticate without an API key.

Send requests to a paid server using /api/. Whitelisting does not remove limits from the free server at free.freeipapi.com/api/v1/.

Whitelisting IPs and Domains

  1. Log in to your account: Go to the FreeIPAPI and log in with your credentials.
  2. Navigate to the IPs and Domains section: Once logged in, go to the "IPs and Domains" section in your account dashboard.
  3. Add a new IP or domain: Click on the "Create" button. You will be prompted to provide the IP address or domain name you want to whitelist.

Only whitelist addresses you control. For backend calls, add your server's public outgoing IP address. For browser calls, add the exact hostname sent in the Origin header; example.com and www.example.com are separate entries.

💡 If you use this method, you will no longer need to use an API key to authenticate your requests.
