Comparison
LayerCall vs Ipregistry
Both answer questions about whether a signup is real. Ipregistry is an IP geolocation and threat data API; 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
An IP geolocation and threat-data API sold as one lookup returning location, network, carrier and currency alongside proxy, Tor and abuser flags — used as much for personalisation and ad targeting as for fraud.
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 Ipregistry’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 Ipregistry’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: Ipregistry’s own pricing page. Product names and trademarks belong to their owners; LayerCall is not affiliated with, endorsed by, or partnered with Ipregistry.
Point by point
Every row is a point we set out to meet. Ours is checkable on this site; theirs is read from Ipregistry’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.
| Point | LayerCall | Ipregistry | ||
|---|---|---|---|---|
| Identifiers scored in one request | Yes | IP, email, phone, domain and device — one call, one key, one quota. | No | IP, by category (IP geolocation and threat data API). Not email, phone, domain and device. |
| Cross-signal linkage | Yes | A device that reappears on a new email and IP is linked, and the link is in the score. | No | Not possible from a single-identifier check: there is no second signal to link IP to. |
| A free tier that needs no card | Yes | 1,000 lookups a month, every endpoint, no card, no daily cap. At the limit it stops rather than billing. | Yes | Every new account gets 20,000 credits on sign-up, with no credit card and no time limit. their page → Checked 3 Sept 2026. |
| Device fingerprinting on every plan | Yes | Included on every plan, the free one too. | Not stated | Not stated on their public pages. Checked 3 Sept 2026. |
| The signals come back with the score | Yes | The signals behind it, and an allow / review / block verdict you tune with strictness. A number alone is unappealable. | Yes | Lookups return location and boolean security flags (is_abuser, is_attacker, is_bogon), not a risk score or threshold. their page → Checked 3 Sept 2026. |
| A test mode that never bills | Yes | Synthetic data, labelled as such in every response, never billed, never written to the shared network. How it works | No | A shared 'tryout' key needs no signup or billing, but is heavily rate-limited and returns real, not synthetic, data. their page → Checked 3 Sept 2026. |
| Repeat lookups are not charged | Yes | Cached repeat lookups are free, every response carries billable_lookups, and you set your own spend cap. | Not stated | Every response carries an Ipregistry-Credits-Remaining header; no statement found on free cached lookups or a spend cap. their page → Checked 3 Sept 2026. |
| Accuracy published with sample size and method | Yes | Published with the sample size, the method and the corpus. The figures | Not stated | Not stated on their public pages. Checked 3 Sept 2026. |
| Verifies an AI agent's signature | Yes | Verifies an agent’s Web Bot Auth signature and decides what a verified agent may do. Agent endpoints | Not stated | Not stated on their public pages. Checked 3 Sept 2026. |
When Ipregistry is the better buy
You want one IP call that answers geography, network AND risk together, and geography is doing real work in your product — localising content, choosing a currency, targeting. Our geo block exists to explain a score, not to be the product, and if location is the thing you are buying then a provider whose whole surface is built around it will serve you better.
