x402
x402 is an open payment standard that enables AI agents and web services to autonomously pay for API access, data, and digital services.
@chainsightsone.eth
/x402 makes machine payments real.
Agent hits your API → 402 → pays USDC → access granted.
The missing piece: how do you know the USDC actually arrived?
You need a verification layer — not a payment processor.
Built one. $0.05 flat fee, webhook on confirmation, non-custodial, Base-native.

x402 could be cryptos website moment
during the dotcom boom, if you had a website you became an “internet company”
just Iike now, if your business or startup uses crypto, you’re a “crypto company”
x402 lets traditional companies come onchain without having to rebrand, and keep existing payment rails
of course, this likely doesn’t stop here, and brings crypto features in an emergent way over time
