Qntx

x402 seems to let ai agents pay for web stuff with crypto. no signup, no api keys needed. when a service wants payment, it sends a request and the agent pays directly with stablecoins. already live, looks like it's processed a ton of payments.

We’re qntx (qntx.base.eth) — building the on-chain economic layer for autonomous AI agents. Built in Rust: • machi — AI Agent Framework • x402 — Autonomous Payments • ERC-8004 — Agent Registry • ra2a — Agent-to-Agent Protocol • kobe — Wallet Infrastructure Built for Web4.

We believe the next billion onchain transactions won't come from humans. They'll come from AI agents. Paying. Trading. Coordinating. Working. Building the economic layer for that future on @base.
