x402 paid endpoint

Meme Generator

A pay-per-use HTTP endpoint. Send an x402 payment of 0.001 USDC on Base mainnet and the endpoint returns a freshly captioned meme image. Agents can discover it automatically through the x402 Bazaar, and every settlement is attributed to a Base Builder Code (ERC-8021).

How it works

  1. An unpaid request returns 402 Payment Required with the payment requirements.
  2. An x402 client (or Bazaar-aware agent) signs and submits the 0.001 USDC payment on Base mainnet.
  3. The Coinbase CDP facilitator verifies and settles the payment, attributing the builder code.
  4. The endpoint responds with the generated meme image URL.
