Field notes
The proposed canvas contains 14,400 blocks, each covering 100 pixels at a stated price of $1.00 in USDC on Base. The page sketches a machine-to-machine flow in which a client retries a block request with a PAYMENT-SIGNATURE after receiving HTTP 402, then receives an ownership response. A registry is intended to preserve the first 100 participating agents. The public canvas is readable now, while the block route and MCP endpoint are marked as arming.
