Search anything. See it first.

Each search is checked as often as every 30 seconds, and about every 2 minutes when many searches share the day's eBay limit; slower only if that limit runs short. Over the 7 days to Oct 23, 2026, half of all cards reached the feed within 3.6 minutes of when eBay says the listing went up, and 9 in 10 within 4.3 minutes (329,820 listings). Most of that time is eBay adding a new listing to its search.

Anything you’d type into eBay’s search box: a couch, sneakers in your size, a tool, a record, a LEGO set, a ring. Pick new or used, and add auctions if you want them. Each new listing that matches becomes a card in your feed. All but a Pass go in your daily email, or come at once if you switch a search to Discord.

Yes. Each search has its own filters: a price range, a shipping cap or free shipping only, words to leave out, a seller feedback floor, a minimum number of seller ratings, sellers to block, and Best Offer only. You can add eBay’s own item filters too, like a category or a shoe size. A filter drops only what a listing clearly fails: if eBay doesn’t give the shipping or the seller’s rating, the card still comes.

LEGO sets; watches; silver, gold, platinum and palladium; trading cards and sports cards; knives. Every other search still alerts you to new listings, marked Unrated.

It could be a deal, but something needs your eyes first: no weight; a value from similar sales, a set’s used or all-condition sales, or asking prices; “silver” that may be a colour, brand or finish; plating; several items under one price; seller feedback under 94% or fewer than 3 ratings; a part sold without the whole; a box, band or papers that may come without the watch; a knock-off, reprint or homage; an opened box; or an auction, where the price is only the bid so far. The card names each one that applies, so you check those and decide.

When we know exactly what it is, from recent sales of the same thing: the same sealed set, card, model or watch, or for silver, gold, platinum and palladium, from the weight and the purity mark. With less to go on, a card is priced off similar sales, a set’s used or all-condition sales, or asking prices, says so, and is never a Buy. It’s an estimate, not an appraisal.

A strip above your searches: up to 24 of the newest listings flagged as a buy in the last 24 hours, each with its photo, price and eBay link. They come from our own searches, not yours, so your max buy doesn’t apply. Close it and it stays closed in that browser until the next day.

No. InstaSnipe never signs in to eBay as you. Each card links to the listing, and you buy it on eBay the usual way.

With your email and a password, or with a one-time link we email you. Try it free emails you a link to confirm your address, and its page lets you choose a password. Skip it and you sign in with emailed links; you can set a password later on your Account page.

New accounts start on one email a day, with up to 40 cards, deals first, and a count of the rest in your feed. Switch a search to Discord and it alerts on each new listing except a Pass. On a very busy search that’s at most 20 an hour, with the rest in your feed. That cap counts only plain new-listing alerts, never a Buy or Review. You can also set a search to deals only, or pause it.

The first comes within about an hour of signing up, if your searches have found something by then. After that it comes once a day at 13:00 UTC, never more than one a day, and a day with nothing new sends no email.

Only if you stop opening what they find. Every search starts on one email a day, and runs for 12 hours after you last open a listing (in the feed or from an email) or add a search, on email or set to off; one on Discord never stops. Each starts again the next time you open a listing or add a search. Your feed counts down the hours left.

The plan runs no AI model. It reads listings with fixed rules and sales data. Three things come from our own searches, which can use AI: Today’s buy alerts; the Detailed analysis line some cards carry, which describes the piece; and a weight marked scale photo, read off a scale in the listing’s photos.

No. Your searches and your feed are private to your account.

It’s free while we launch, and we haven’t set a price for after that. We’ll email you at least 14 days before anything changes, and you can stop using it at any time.
