Read the notification
In about 3 seconds you get the card, its market price and your max bid after fees, shipping and margin.
What the notification means
Three real results, word for word.
Mew ex · MEW 205 · mkt $25.16 · MAX BID $16.71
It knows the card and the print. Bid up to $16.71 and you still clear 13% fees, $1 shipping and your 20% margin.
Salamence · SW 18 · $15-38 · SAFE BID $9.73 (assumes reverse holo)
It knows the card but not which printing, so it bids off the cheapest one it could be. You might lose the auction. You won't overpay.
Snorlax · PAF 202 / CL 016 / SWSH11: TG TG10 / SWSH06 224 · mkt $17-$142 · can't confirm print, no bid
Only the name and "full art" were readable, and four Snorlax full arts sell for $17 to $142. It won't guess, so there's no bid.
When bidcheck isn't sure, it says no bid. A missed auction costs you nothing. A wrong max bid costs you money.

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?
Not yet. bidcheck prices English cards only. A Japanese card gets "not covered" and 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.
