Inspiration

AI agents are becoming powerful content consumers, but they struggle to pay for premium content access. Traditional payment rails aren't designed for agent-to-creator micropayments. We built CreatorPay to solve this.

What it does

CreatorPay enables AI agents to automatically pay creators for content access using the x402 protocol on Base L2. Creators can:

  • Gate premium content behind micropayment walls
  • Set flexible pricing (per-access or subscription)
  • Get instant payments from AI agents
  • Track agent engagement analytics

How we built it

  • Backend: Node.js + Express.js API handling payment flows
  • Database: PostgreSQL for user accounts and transaction history
  • Payments: x402 protocol implementation on Base L2
  • Frontend: React dashboard for creators to manage content and view analytics
  • Smart Contracts: Custom payment routing contracts on Base

Challenges we ran into

  • Implementing efficient micropayment batching to reduce gas costs
  • Designing an agent-friendly authentication system
  • Creating a simple SDK for agents to integrate payments
  • Building real-time analytics without impacting performance

Accomplishments that we're proud of

  • Sub-second payment processing for agent requests
  • Gas-optimized smart contracts reducing costs by 80%
  • Clean API that agents can integrate in minutes
  • Working demo with real AI agents making payments

What we learned

  • The x402 protocol is perfect for agent-to-human micropayments
  • Base L2 provides the speed and low costs needed for this use case
  • Creators are excited about new revenue streams from AI consumers
  • Simple integration is key for adoption

What's next for CreatorPay

  • Multi-chain support (Optimism, Arbitrum)
  • Content recommendation engine for agents
  • Creator collaboration features
  • Mobile app for on-the-go analytics
