Not at all. Most teams integrate Smarty in hours, not weeks. Our APIs and SDKs are well-documented, easy to swap in, and backed by top-notch support—so you can start getting cleaner, more accurate addresses fast.

Yes and no.

You can get it cheaper on the front end but more costly on the back end. Also, some providers play “credits” shenanigans, making it difficult for you to understand your actual costs. Smarty's pricing is clear.

It’s a "let's-be-transparent" and “get-what-you-pay-for” kind of thing with significant consequences following implementation.

Be aware that cheaper will mean less accurate and higher operational costs. Smarty gives you global coverage, lightning-fast address lookups, and top-tier accuracy—so you save more in the long run by avoiding failed deliveries, wasted postage, and bad data costs. Smarty is your Goldilocks solution; we’re not the most expensive and we’re not the cheapest, but we are the best value and drive the best ROIs.

Pretty much just your time—and not much of it.

Yes. Smarty offers International Address Autocomplete that works seamlessly with address verification. You’ll get real, valid suggestions as users type—no fake or incomplete addresses. Every address will be standardized in the format of its respective country.

Rest assured that the APIs work seamlessly together and are both supported with stellar SDKs filled with examples and sample code to make integration a snap.

You’ll receive the correct mailing format for the country, plus every part of the address returned as individually parsed components. Additionally, we'll tell you the occupant use: whether the address is commercial or residential. See the International Street Address API doc.
