Heads up. [crypto] Mermail also runs an x402 marketplace of paid services and an optional Agent Wallet for agent payments. Wallet funding is separate from the free inbox. The Free plan is owner only, uses a Mermail-hosted address (custom domains start at $19 a month) and allows 10 API requests a minute.
