# What a purchase hands back

A free, unsigned sample of the Once-Over — the $5 signed audit of one x402 endpoint. Every field a buyer gets, run against a door that fails on purpose so the sample shows the instrument working.

## What this is

A free, unsigned sample of the Once-Over — the $5 signed audit of one x402 endpoint at one moment. Every field below is the field a buyer gets, produced by the same check battery the paid artifact runs, against a constructed door that fails on purpose so the sample shows the instrument finding something rather than a column of ticks.
