OPTCG Vault

How pricing works. None of these sites offers a free public API a page like this may call, so prices are yours to enter - the app never invents a number. What it does do is cut the work: tap Search once, find the card, then tap 🔗 to remember that exact page, and every later check is a single tap. Paste "JPY 4,200" or "US$ 38.50" and the currency sets itself. Sweep mode walks the queue one card at a time. Refresh prices reads SNKRDUNK's English site for you, in SG$, the same figures you see when you tap Search yourself. TCG Republic turns servers away, so a script on your PC reads it with your own Chrome and you import the file under Import / Export (README: "Reading TCG Republic from your PC"). TCGplayer is deliberately absent: its One Piece catalogue is English only, so its prices would drag a Japanese card's value the wrong way. SNKRDUNK's search cannot be linked to from outside, so for that one the saved link really is the difference between one tap and typing the name in Japanese every time. Every save is kept as history, so trends build up as you go.
