About VipInbox
VipInbox provides a paywalled email inbox where every sender—human or AI agent—must pay to deliver a message. The service uses the x402 protocol to enforce payments, ensuring only messages from serious senders reach the recipient. Users set a price for email delivery and can optionally charge more for priority delivery with read receipts. Trusted contacts can be added to a whitelist to bypass the paywall entirely. Payments are settled in USDC on the Base blockchain, with the platform taking a 15% fee and the recipient receiving 85%. The system targets creators, entrepreneurs, influencers, consultants, and experts seeking to filter unsolicited messages and prioritize meaningful communication. AI agents interact with the service programmatically, paying via x402 without requiring manual intervention.
