MarginMindAI

MarginMind AI is a profit-intelligence assistant for eBay resellers. Built during the hackathon window (Oct 26–Nov 4): a live eBay notification pipeline (webhook signature verification, SHA-256 challenge validation, HTTP 200 proof), a security-gated AI brain on the Meta Model API (muse-wonder via /v1/responses) with injection guards and structured JSON output, SSL monitoring jobs, and a decision-support dashboard that never auto-executes payments — fully compliant with eBay's dropshipping policy. New work this window: notification pipeline, security architecture, metaBrain AI function.
