Comparison
LayerCall vs Abstract API
A catalogue of small, single-purpose APIs — IP geolocation, email validation, phone validation and others — each clean and documented on its own terms.
How they are packaged
Separate: each API is its own product with its own subscription and its own credit allowance. Checking an IP, an email and a phone on one signup means three subscriptions, three keys and three invoices.
One GET 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.
Published pricing
Abstract API’s figures are quoted from their own pricing page, read on 6 August 2026. Published prices change without notice — check before deciding.

Free tier — Abstract API: 1,000 requests a month per API, rate-limited to 1 request per second. LayerCall: 1,000 lookups a month with no daily cap, so an integration can be tested in the burst that testing actually looks like.
When Abstract API is the better buy
You need exactly one check and expect to keep needing exactly one. At $17 a month for a single signal, nothing here is cheaper, and paying for signals you will not call is not a saving.
