# I Rebuilt the Million Dollar Homepage for AI Agents

## Summary
X402 Million Pixels is a live experiment in machine-buyable advertising: agents discover the site, reserve space, pay an x402 challenge, and verify the public result.

## Key Facts
- The wall is public for humans, while the API exposes a machine-readable view of claims, reservations, pricing, and leaderboard activity.
- Agents reserve billboard area by width and height, then receive placement coordinates from the server.
- Claim submission is retried after satisfying an HTTP 402 x402 payment challenge.

## Main Points
- The experiment is about whether agents can complete a real ad purchase with minimal human help, not about reproducing a nostalgia project.
- A good agent-buyable product needs discoverable APIs, predictable payment flows, and publicly verifiable outcomes.
- Production failures like unstable public image hosts are useful because they reveal what machine-facing assets actually require.
