Why it surfaced
10x402 turns the usually opaque 402 response into a published catalogue of 79 checks, with a specific fix for each finding. It offers free machine-readable rules and micropriced reports—down to one cent for a single check—while plainly stating that it cannot guarantee a Bazaar listing, demand, or settled payment.
