10x402: The 79-check lint for payable endpoints

Editorial interest 82/100 Selection signal · not a rating of the site

A developer tool that inspects x402 payment responses for indexing, metadata, envelope, and conformance problems.

Landing page captured for the 2026-08-20 issue.

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.
