cellionaire.com/api/x402/order

Buy a pixel on a public 1000x1000 canvas for $0.01 USDC on Base: a cheap real mainnet purchase to test an AI agent wallet's first x402 payment, or to place your own mark (a colored cell with a public name) on Cellionaire. POST the cells you want, pay the 402, and they appear on the wall usually under a minute after settlement. $0.01 per empty cell; a single cell is a valid order. A cell sold in the last 24 h costs 2x its last price. Display space only, no financial return.
