Adam and Ryan recently demonstrated how to build a functional application using ChatGPT to generate large amounts of code. Read all about it here!

In our recent webinar, we brought together two of our software engineer experts, Adam Charlton and Ryan Cox, to demonstrate how to build a working application using ChatGPT to generate most of the code.

We know what you're thinking: ChatGPT can't take our jobs; we've tried.

This is wonderfully true. ChatGPT can pull together useful bits of information but still needs to be guided and curated by a human, preferably one with subject knowledge.

The exact working scenario given by Adam and Ryan was:

Write code in Python that takes an address and delivers the ten closest addresses to that address. The use case is you have a client that like your services, and you want to advertise to all of their neighbors.

On the first run, ChatGPT did deliver code that, when plugged into the terminal, pushed out an address. Unfortunately, it was only the exact address that was input.

One of the critical points that Ryan and Adam spoke about is knowing how to debug the code that ChatGPT spits out.

Here are some tips they gave us in spot-checking code from ChatGPT.

ChatGPT only has knowledge through September 2021: When you ask ChatGPT to write code referencing data on a website, know that it’s pulling that data from the 2021 version of that website. When we asked it to look at the Smarty code, we had to reference SmartyStreets, our company name, in 2021.

Be very specific, or ChatGPT will guess: We asked ChatGPT to use a Smarty address API to solve our problem, but we weren't specific about which one. ChatGPT then pulled the first API it found that met the criteria, and we had to adjust our request to find the specific API needed.

If you want specific data to be referenced, feed that data to ChatGPT: While its general knowledge is several years old, you can feed ChatGPT reference code or data to pull from in its next response. There's, of course, a risk of giving it proprietary information, so be aware of that.

ChatGPT is not deterministic: You can ask the same question of ChatGPT several times and get a different answer each time. This can cause problems if you're leaning on ChatGPT too heavily.

Looking to build a direct mail marketing campaign? You’ve come to the right spot. Before you can send marketing mail like a pro, you’ll need to build a list of verified addresses. Otherwise, frequent misdeliveries and costly redeliveries can take the wind right out of your campaign’s sails. On top of that, a bad address list could lead you to miss out on mind-blowing postal discounts. 😱Don’t let bad addresses capsize your campaign. With a US Master Address List of over 210 million verified addresses—available by state, county, or nationwide—and shipshape US Address Verification, you can construct new lists or clean active ones with the swagger of a seasoned captain.
USPS API rate limit capped at 60 requests per hour: How to prepare and why many are choosing Smarty

Because who doesn’t love juggling one more thing during the holiday season…? A major shift in the address-verification landscape is approaching at the beginning of the new year. On January 25, 2026, the United States Postal Service (USPS) will officially retire its long-standing Web Tools APIs, a free API that previously allowed for approximately 5 address lookups per transaction. This includes the legacy USPS Address Information APIs that many organizations have depended on for years. Under USPS’s new API structure, the default quota for many services, including the Addresses API, is 60 requests per hour.

For two days, Smarty users gathered together with other address data experts for Pinpoint, Smarty’s first virtual user conference, where developers, industry experts, and product specialists talked all things addresses and pulled back the curtain on address data solutions. Attendees asked questions about cloud-based software, the impact of accurate address data on fintech and insurance companies, and the ROI of good address data across all industries. Plus, attendees got to take a peek behind the scenes and see what makes Smarty’s address data solutions tick.
