One call. One decision.

Send email, phone and IP together. Get allow, review or block, plus every signal behind it.

You decide the policy: ask for extra verification, hold the trial credits, or block outright.

Unknown stays unknown. We never guess a field, and you're never charged when we fail.

Where fake signups come from

Throwaway inboxes.

About 9,900 known disposable domains, refreshed weekly, plus a live check that the domain can actually receive mail.

Live: domain, disposable, role and free-provider checks

Server and anonymised traffic.

Signups from 13 major cloud and hosting networks and from Tor exits, refreshed daily, are flagged for review.

Live: location, network, hosting and Tor

Fake numbers.

Malformed and impossible phone numbers are rejected for every country. Outside the US and Canada you also see whether it's mobile, landline or VoIP.

Live: validity, format, country and number type

Works where your signups happen

API

One endpoint, an OpenAPI spec and idempotent retries.

Auth0

A Pre User Registration Action that flags or blocks before the account exists.

AI agents

An MCP server for AI agents and coding tools.

CSV

Check email and phone columns together, or upload an IP list to see hosting-network and Tor flags.

$99/month for 20,000 checks.

About $0.005 a check, with no overage charges. 7-day trial with 500 checks.

What it checks, and what it doesn't

  • Phone validity, format, country, and number type outside the US and Canada.

Signals help you decide; they don't prove fraud or identity.

Three endpoints. One response shape.

  • Idempotency keys. Retry safely; a repeat never runs or charges twice.
  • null means unknown. A missing field is never filled with a guess.
  • Free when we fail. Supplier errors and timeouts cost 0 credits.
  • OpenAPI 3.1. Generate a client in any language. Read the reference
