1Lookup

1Lookup checks contact data so you can trust it before you call, email, or let someone sign up. With this connector, Claude can: - Validate a phone number: whether it is real and active, mobile or landline, the carrier, Do Not Call status, and a risk level. - Verify an email address: whether it exists and can receive mail, and whether it is disposable, role-based, or risky. - Look up an IP address: location, connection type, proxy, VPN, Tor and data-center flags, public blocklist hits, and a risk score. - Check up to 50 phones, emails, or IPs in one go. - Show your plan and remaining credits. Lookups use the same credits as the 1Lookup API: one credit per check. Checking your plan and credits is free. Nothing in your 1Lookup account is changed or deleted. Sign in with your 1Lookup account and press Approve. No API key to copy. Disconnect any time from Claude's connector settings. Needs a paid 1Lookup plan. Every plan starts with a 7-day free trial.
