Who builds with Cartpie.
Four shapes of teams keep landing on the same problem — and the same fix.
AI shopping & comparison agents
Pain
Your agent needs price, availability, and variants for arbitrary URLs — but every retailer returns a different DOM.
Fix
Normalized product JSON for any URL, exposed as a single MCP tool. Your agent reasons over 1.5 KB, not 200 KB of HTML.
const { data } = await cartpie.extract({ url });
agent.tell(`${data.title} is ${data.price} ${data.currency}`);Price trackers & deal apps
Pain
You're maintaining brittle scrapers per retailer. Holiday season breaks half of them.
Fix
One endpoint that returns price + originalPrice + availability on a schedule. We keep the plugins running, so you don't.
for (const url of watchlist) {
const { data } = await cartpie.extract({ url, freshness: "6h" });
if (data.price < threshold) notify(user, data);
}Affiliate & content sites
Pain
Manually refreshing product cards across many retailers doesn't scale, and stale prices erode trust.
Fix
Fresh title + image + price + GTIN for any retailer URL in one call. Plug into your CMS or static-site build.
// at build time
const cards = await Promise.all(
picks.map((p) => cartpie.extract({ url: p.url }))
);Resale, dropship & inventory
Pain
The same product lives at 10 different retailers under 10 different listings. Matching them is a project.
Fix
GTIN-based identifiers in every response. Dedup, compare, and route to the cheapest available source automatically.
const offers = await cartpie.findOffers({ gtin: "07391440264259" });
const cheapest = offers.sort((a, b) => +a.price - +b.price)[0];
