xFour

This platform functions as a programmable payment gateway that enables autonomous AI agents to transact, pay for services, and manage non-custodial treasuries using a USD-backed stablecoin, eliminating manual approvals and human-in-the-loop bottlenecks.

Core features include programmable spending policies and per-agent API keys with workspace isolation, real-time analytics and audit trails, non-custodial smart-contract treasuries, automatic token swaps to settle in the required currency, and a drop-in SDK for seamless agent integration, all aimed at developers, researchers, and teams building autonomous AI services who need secure, transparent, and scalable payments.
