Why people look beyond 1lookup
These are limits 1lookup states on its own pages.
- API access needs a paid plan, so an account on the free plan cannot call the API. Source
- Lookups that fetch live data can take seconds on a first call, and its guide advises a client timeout above 60 seconds for them. Source
- Enrichment and intelligence products draw from 2 up to 86 credits a lookup, so the price of one call depends on which product it is. Source
Pricing model: Subscription.
Shortlist in several lookup areas
Ranking rule: Lowest per-1,000 price in US dollars first, at the best volume tier the page prints, with the lookup each figure covers named beside it. Where a page prints only a price per request, the per-1,000 figure is our arithmetic and is shown as "about". Providers with no dollar per-1,000 figure we can compare come after, and ties go by name.
| Rank | Provider | Free result | Paid result | How it bills |
|---|---|---|---|---|
| 1 | Abstract API | Free tier of 100 requests a month for email and phone, 1,000 for IP, with the full response and no card. Source | Phone Validation Starter: $19, per month paid monthly, 5,000 phone requests Source | Subscription |
| 2 | LookValid | Free tools run the same data without an account, up to 25 lookups a day per visitor. | Phone Numbering-Plan Validation: $2.00 to $4.95 per 1,000 lookups across the plans; IP Intelligence: $2.00 to $4.95 per 1,000 lookups across the plans; Phone Spam Check: $2.00 to $4.95 per 1,000 lookups across the plans; 6 more lookups priced below | Monthly plans with credits |
