Prism 在 Robinhood Chain 上线 x402 支付墙
Prism 推出面向 agent 的 HTTP 402 支付墙，六个行情数据源按次用 USDG 付费，交易哈希转为预付费余额。
Making RWAs easy for AI agents: We’re building the first independent agentic payment facilitator and payment rails on Robinhood Chain, similar to x402 / HTTP 402. The Robinhood Chain x402 facilitator, operated by Prism. For now, Prism’s HTTP 402 paywall for agentic payments is live. We currently have six machine readable market data feeds behind an HTTP 402 paywall, x402-style, paid in USDG on Robinhood Chain. An agent calls a feed, receives a 402 with a machine-readable payment challenge containing the asset, treasury address, and price, then sends a USDG transfer. That transaction hash becomes a prepaid balance, which is debited per call across all feeds. Check it out: prismassets(.)shop/agents
