Lookup is one universal endpoint that validates phone numbers, emails, IP addresses, and domains — automatically detecting the type and returning enriched results in under 300ms. No stitching together multiple APIs. Just send a query and get back carrier data, MX records, geolocation, VPN detection, and more. Built for developers who can't afford bad data in their systems. Starts at $99/mo.
Hey everyone Massimo here.
I built 1Lookup after getting frustrated with managing separate APIs for phone, email, and IP validation. Every project needed all three, and the setup cost was killing momentum.
The idea was simple: one endpoint, send anything, get back everything you need. No type detection on your end, no juggling API keys, no stitching responses together.
Would love to hear what data points you'd want added next — carrier name, email deliverability scoring, and IPv6 support are already on the roadmap. Drop a comment and let me know.
Spent 10 minutes hitting it with random phone numbers and emails and the auto-detection actually nailed it every time. Response time is honestly impressive for under 300ms.
Honestly the auto-detection thing is pretty slick, sent a mixed batch through and got back carrier plus geo data without having to flag anything myself. Speed was solid too, felt basically instant.
Preventing bad data before it spreads usually creates much more value than cleaning it later. Curious where you've seen the biggest impact so far.
The unified endpoint idea is genuinely useful, but having some kind of batch lookup option would be a game changer for cleaning up an existing user database. Right now it seems like I'd have to ping it one record at a time, which gets expensive and slow for tens of thousands of rows. A simple CSV upload or bulk API endpoint with a flat rate per record would make this way more practical for the migration use case.
Handy having one endpoint that figures out what you're throwing at it instead of wiring up separate validators. Carrier data and VPN detection came back fast in my quick test.
Finally tried it on a sketchy signup and it nailed the phone carrier and flagged the IP instantly. Love that one endpoint handles all four types without messing with multiple API keys.
