Which currency does it answer?

The currency of the country the address is in: its ISO 4217 code, name and symbol, on every plan with no key.

Can it catch a coupon abuser's throwaway email?

Yes, with a domain lookup on a paid plan: is_disposable marks a disposable email domain and names the providers behind it. has_mx, on every plan, says whether the domain publishes a mail server at all.

How close is the city to the shipping address?

Check the country first, then the city: a paid answer's city comes with accuracy_radius, the kilometers around it that hold the true location with 67% confidence.

What about shoppers on mobile data?

A carrier's address answers with its country and network like any other, with is_carrier set on every plan, and a paid plan names the carrier. Only one that's also resold as a proxy answers is_mobproxy.

Sell to real shoppers, in their own currency.

One lookup per visit says where a shopper is, what currency they pay in and whether the order comes through a proxy pool or a hosting server. A domain lookup says whether their email will ever answer.

Card testing
Bots try stolen cards through proxy pools so each attempt looks like a new shopper. Hold orders from proxy exits for review.

Shipping mismatches
An order ships to one country from a connection in another, behind a VPN. Review it when the address disagrees with the shipping country.

One answer for the order, one for the email.

The country, currency and timezone, Tor, relays and a domain's mail records answer with no key and no daily or monthly cap. Proxy, VPN and hosting flags, the city and postal code, and the disposable flag come with every paid plan, and Pricing lists every field by plan.

01
On the first page
Read the country and currency as the page renders, so prices show in the shopper's own money. Keep their own choice once they make one.
02
At sign-up
Look up the email's domain before sending a confirmation. A domain with no mail server, or a disposable one, never reaches your list or your coupons.
03
At checkout
Look up the order's address. A proxy exit, or a country that disagrees with the shipping address, goes to review, and a home connection goes straight through.

On this page

Should every order from a proxy be refused?

Usually not. Hold it for review: a residential proxy exit is often a real household's connection that's also resold. A paid plan's resproxy object says on what share of the last 90 days the address was seen as one, so a rule can weigh it.
