@GoKiteAI x402 🤝 Kite

x402 is now integrated with Kite mainnet and Kite agent passport. With mainnet live, AI agents can use x402 to pay major e-commerce merchants, book travel, and call paid APIs, all in stablecoins, in a single HTTP round-trip, with no accounts or sessions. Together with Kite Agent Passport, providing agent identity and governance, and Kite mainnet settling instant stablecoin payments, x402 + Kite enables agents to pay with trusted delegation from humans, preserving both control and trust. Go try it now: agentpassport.ai

Agentic wallet is now multi-chain! The same self-custody, configurable guardrails, and x402 skills, now available on @solana and @0xPolygon. 🚀

Agents can now buy real-world goods with @agentcashdev + @rye (powered by x402): → Access products across 15,000+ merchants → No API key required From intent to delivered order, end to end.
