AI agents just started buying event data — by the query. Belong launched Long Events today, a live event-data platform built for AI agents, covering 400 cities across 118 countries. Each query costs $0.005, paid in USDC on Base. That means $1 covers 200 queries. No credit card, no checkout page, no human approving each charge. The catalog holds 500,000 events, 180,000 venues and 80,000 artists. Bitcoin trades near $78,000 while the machine-to-machine economy quietly gets its own payment rail. When software starts paying software, half a cent at a time, the question is what it buys next.
