## About 1Lookup

1Lookup is one API for the data checks most apps end up building piece by piece. Instead of signing up with five different vendors for phone validation, email verification, IP scoring and enrichment, you get 70 data products behind a single key and pay per lookup.

Phone validation tells you the carrier, the line type (mobile, landline or VoIP) and whether a number carries spam or fraud risk, so sign-up forms and sales teams stop wasting time on bad numbers. Email verification checks an address before you send, which protects your sender reputation and keeps bounce rates low. IP intelligence scores visitors for VPN, proxy and fraud signals at checkout or sign-up. Contact and company enrichment fills in the missing details on a lead, and the social and SEO endpoints pull public profile and search data on demand.

It is built for developers and for AI agents. The REST API works from any language, the docs include copy-paste examples, and agents can call every product directly through the 1Lookup MCP server and agent skill, so an AI workflow can validate a phone number or verify an email in the middle of a task.

Typical uses: cleaning a CRM before a campaign, blocking fake sign-ups, routing leads by line type, scoring risky orders, and giving an AI sales agent real data to work with.

Plans start at $99 a month, and every plan starts with a 7-day free trial.
