// Why Grailsnap
A free alert on any single marketplace stops at "it's listed." Grailsnap is the layer above: it watches every marketplace we cover at once and gives you, the buyer, the price intelligence to make the smart call the moment it matters.
Every marketplace in one stream, including the ones you can't watch yourself: Japan, Europe, dealer drops, and more on the way.
No more juggling a dozen saved searches and inboxes across a dozen sites. One account, one feed, only the matches that count.
Not just that it exists, whether it's worth buying. A live market-value read, above or below, so you, the buyer, can make the smart call.
Exact grade and condition matching, so you hear about the one thing, not forty near-misses. Near-instant scanning on Hunter and Curator.
One good catch, or one overpay avoided, pays for the license.

// How it works
01
Add the exact things you're hunting: by name, set, year, grade, marketplace, price range. Granular as you want, broad as you need.
02
Our scanners poll each marketplace as often as its API allows: roughly every 15 minutes on the free tier, about 5 minutes on Watcher, and near-instant (about a minute) on Hunter and Curator. As fast as the source lets us go.
03
An alert hits your inbox with the listing, the price, and a market-value read where we have it. Tap through, buy, win.
// Becoming a Partner
We're always expanding the marketplaces we watch. If you run a marketplace, auction house, or specialist shop, we'd love to get your listings in front of buyers actively hunting exactly what you sell, with full attribution, links straight back to you, and the sale always completed with you.
// The 50 · open since June 2026
Free for the first fifty.
We'll write the moment your seat opens. When we launch, the founding fifty lock in the Watcher tier for life, our thanks for being here early.
Alerts shouldn't have a monthly bill.
