KEYINSIGHT
I paid 10 brand-new x402 sellers and checked every answer. All 10 were right.
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.
- All 10 answers were right. The dollar to peso rate matched the ECB to four decimals. The SEC 8-K feed matched EDGAR filing for filing. The French company search matched the government registry. Card prices matched TCGPlayer.
- Two stood out. stocks.cyberwarex.com returned Apple's current revenue, $416.2 billion, for less than half a cent. AnswerPool got that wrong two weeks ago with a 2018 number. And a sanctions screener correctly said Tornado Cash is no longer on the US sanctions list, while still flagging it as a mixer.
- Two I couldn't buy, and neither charged me. ax1.vc, the one new seller with real buyers, quoted a price and then asked me to sign in. war-tracker.com only takes a payment type my wallet couldn't complete.
