About
1Lookup is one API for the data checks most apps end up building piece by piece. Validate phone numbers (carrier, line type, spam risk), verify emails before you send, score IP addresses for fraud and VPN use, enrich contacts and companies, and pull social and SEO data. There are 70 products behind one key, priced per lookup, so you pay for what you use instead of stitching together five vendors. It works from any language over REST, and AI agents can call it directly through its MCP server and agent skill. Every plan starts with a 7-day free trial.
Key Features
- Validate phone numbers with line status, carrier data and DNC checks
- Verify email deliverability through syntax, MX record and live SMTP checks
- Score IP and phone risk, flagging VPN, proxy and spam activity
- Run single or batch lookups from one API key and shared credit balance
- Transcribe audio with speaker labels and word-level timestamps
- Pull SEO authority scores and backlink counts for any domain
