A transaction approval layer that sits between your AI agent and real purchases. Instead of letting Claude or ChatGPT charge your card unchecked, you define spending thresholds, vendor blocklists, daily caps, and category restrictions. Requests under your auto-approve limit go through instantly. Anything outside your guardrails gets routed to your phone for manual approval. Includes rule templates (Conservative, Moderate, Permissive), a real-time dashboard at app.spendnod.com showing pending approvals and spend history, and a full audit trail. Useful if you're building agentic workflows that need to book services, place orders, or move money without giving them carte blanche access to your accounts.
