Verified datasets, graded before they list
Every listing carries a verification stamp and a KB Quality grade, so you can compare like for like before you pay.
Is the seller telling the truth, and is the data any good. We answer them separately, because a modest honest card on great footage should do well, and an inflated card on the same footage should not.
01 · Verification
Is the card true?
Every factual claim on the dataset card is checked against the actual files. Each claim comes back with one of three stamps, always with the evidence attached.

02 · KB Quality grade
How good is the footage?
An independent grade from A+ to F on four quality pillars, using the same versioned weights for every seller, so a grade means the same thing everywhere.
A+ to F, no E. The full scale, with what earns each grade, is on the trust page.
