GradeRoute

HOW IT WORKS

Your stream. Useful context.

GradeRoute works alongside supported Whatnot streams in desktop Chrome. You choose when to start.

01

Install & link

Install the free extension and sign in with Google. Your website and extension share an account, with separate secure sessions.

02

Watch & start

Open a supported stream and choose Start. One participating capture holder supplies images for a broadcast, with results shared among authorized viewers.

03

Read & compare

View recognized slab details or raw-card candidates. Available price context depends on a supported match, sales coverage, and your plan.

Clear about what we know

Raw-card artwork can match more than one language, edition, or print. Candidate matches stay uncertain, and selecting a chart does not confirm that the auction card is the selected version.

Slab comparisons rely on supported identity and exact-grade evidence. Missing or stale sales can mean a limited chart or no price. Whatnot paid-sale points appear only where eligible data is available; headline comparisons remain eBay-based.

Made for desktop viewing

The supported installation path is desktop Chrome on Whatnot. Other browsers, platforms, graders, and universal card coverage are not promised. Service or source outages may interrupt results.

You’re always the bidder

The extension provides information. It never bids, buys, or guarantees a card’s value. Review the evidence and the actual card before making a decision.
