APEX-AGENT is a multi-agent autonomous B2B sales system built on AMD MI300X GPUs using vLLM and ROCm 7. Five AI agents collaborate in a ReAct loop: Scout finds leads via web search, Analyst scores and enriches them, Outreach writes personalised cold email sequences, Payments handles X402 micropayments autonomously, and Memory manages a persistent SQLite CRM. The key innovation is the X402 Payments Agent — when any agent receives an HTTP 402 response from a paid API, it autonomously signs and broadcasts a USDC micropayment on Base, retrieves the payment token, and retries the call without human intervention. Built for KGA Results digital agency in Gaborone, Botswana.
