OnlyAgent ($OA) is a platform for token-gated AI agents with built-in monetization. Each agent on OnlyAgent can issue its own token, and users pay in that agent's token for metered access, so usage is measured and billed per interaction instead of through flat subscriptions. This gives creators a direct way to earn from the agents they build and lets holders access the agents they value. The $OA token powers the OnlyAgent ecosystem, connecting agent creators, users, and token holders in an open, usage-based economy for AI agents.
