Comparison
LayerCall vs IPinfo
Both answer questions about whether a signup is real. IPinfo is an IP data provider; LayerCall returns IP, email, phone, domain and device from one request. Which is the better buy depends on how many of those you need to ask about.
What each one is
IP data done thoroughly — geolocation, ASN, carrier and privacy detection — from a company whose entire product is the IP address.
Their current pricing →One request returns IP, email, phone, domain and device together, on one key and one quota — because the signal that catches a fake signup is usually the relationship between them, and that relationship does not exist inside any single check.
Our pricing →We never quote IPinfo’s prices. Where the table below states a fact about them, it is read from their own public page, linked beside the claim with the date we read it, and dropped if it goes sixty days unchecked. Their pricing is linked above and is always current.
About IPinfo’s side of this page: we describe what kind of product it is, and where we state a fact about it we quote their own public page, link to it, and show the date we read it — and we never quote their prices, which change without notice. Where their pages do not say, we say that rather than guess. Anything current comes from them: IPinfo’s own pricing page. Product names and trademarks belong to their owners; LayerCall is not affiliated with, endorsed by, or partnered with IPinfo.
Point by point
Every row is a point we set out to meet. Ours is checkable on this site; theirs is read from IPinfo’s own public pages, each claim linked to the page it came from and dated. A dash means their pages do not say — which is not a no.
