Hi folks! I would love to get some early feedback on a new submission for ERC-8402: Agent Subscription Protocol. The agentic economy is converging on two complementary primitives: identity ( ERC-8004 ) and per-request payments (x402). Per-request payment works well for traditional APIs where the cost of fulfilling a request is known in advance. Agent interactions are fundamentally different: the work required depends on the prompt, users rarely achieve their goal in a single message, and agents themselves may need to ask clarifying questions, with each exchange triggering another payment. This makes per-request billing unpredictable for users and friction-heavy for multi-turn conversations. A subscription model is a better fit: An AI coding assistant used daily is cheaper as a monthly subscription than per-request billing, and users can iterate on prompts without worrying about per-message costs. An agent providing continuous monitoring (portfolio, security, social) needs persistent access authorization, not a payment negotiation on every check. Agent-to-agent collaboration benefits from pre-established payment relationships that reduce per-call friction. No existing standard covers recurring, tiered access to agent services. This ERC fills the gap with a protocol that: Requires zero offchain infrastructure from agent developers. Subscribe, renew, and access verification logic is handled entirely onchain. Integrates with ERC-8004 for agent identity and discovery. Supports multiple plan tiers per agent, enabling differentiated service levels. Gives users full control with cycle-based prepaid billing, where subscriptions simply expire at the end of the paid period.
