I paid 10 brand-new x402 sellers and checked every answer. All 10 were right.

this week's new sellers, paid and checkedone call each, receipts archived
Sellers that showed up in the last two weeks, one call each, checked against the real source.

Most new sellers never get a single customer, so I became one. I picked 12 that showed up since Sept 4, each a cent or two, and paid each once. Ten sold to me, for 5.1 cents total.
