How it works

  1. 1

    Add the button once

    One tap adds the bidcheck Shortcut, and a floating button stays on your screen. See the setup

  2. 2

    Tap it on any live

    When a card face fills the screen on Whatnot or TikTok, tap the button. You never leave the stream.

  3. 3

    Read the notification

    In about 3 seconds you get your max bid first, then the card and its market price. The bid is after fees, shipping and margin.

Tested on 128 real stream frames: right card about 9 in 10. When it isn't sure, it bids low or not at all.

Works on English and Japanese Pokémon cards, raw or graded, and reads graded slab labels. Some Japanese cards don't have market prices yet, so you may get a price range or no bid.

Prices are raw near-mint TCGplayer market prices. Graded slabs, 1st Edition and special variants can sell for far more. When bidcheck can't tell which printing it is, it gives a safe bid off the cheapest one, and "no bid" when it can't tell the card.

Questions

Which apps does it work on?

Whatnot and TikTok lives on an iPhone with iOS 14 or later and the Shortcuts app. The button reads whatever is on screen, so it works best when one card face fills it. On a computer, check a screenshot in the web app.

Does it work on Japanese cards?

Yes. bidcheck works on English and Japanese Pokémon cards, raw or graded, and reads graded slab labels. Japanese cards are matched by the set code and number printed at the bottom left, or by the slab label. Some Japanese cards don't have market prices yet, so you may get a price range or no bid.

How are prices calculated?

From TCGplayer market prices for raw near-mint copies, refreshed every night. Graded slabs, 1st Edition and special variants can sell for far more, so treat the bid as the raw card's.

What does the max bid include?

The market price minus 13% marketplace and payment fees, minus $1 shipping, minus your margin: 20% unless you change it. Bid up to that and the flip still pays.

Can I cancel anytime?

Yes. Free needs no card. A paid plan cancels from your account with Manage plan, and checkout and billing run through Stripe.

Stop guessing on the clock.
