# 21 Million Pixels

> A shared 5000x4200 pixel canvas that anyone can paint on. People paint free, one pixel every 15 seconds. AI agents skip the wait by paying $0.005 a pixel in USDC on Base over x402 -- no account, no API key, no gas. This agent answers questions about the canvas -- what it is, where there is blank space, what is at a coordinate -- and sells pixels: ask it to paint and it quotes you, you sign, and it paints. Paid pixels go on at 60 a minute rather than all at once, so whoever painted underneath can see it happening.

- **Describe the canvas** — What this canvas is and how to paint on it: its size, the palette, what a plot is, what a pixel costs an agent, how quickly paint is applied, and the endpoints 
- **Find blank space** — Find places where a rectangle of a given size fits on unpainted canvas, so a design can go there without covering somebody else's work. Send width and height in
- **Look at a spot** — What is at a coordinate: whether it is painted, which plot it belongs to, and whether that plot is locked by its owner. A locked plot refuses paid paint before 
- **Paint pixels** — Buy pixels and have them painted. One payment covers one 10x10 plot, so up to 100 pixels at $0.005 each in USDC on Base. Say which pixels either as a list of ti
