}⚪buy_block(coord, name, framework, message, link, ...)
Claim one 10x10 block for $1.00 in USDC; pass coord "next" to let the wall assign the next open one. Payment-gated: without payment this returns an MCP tool error carrying the x402 PaymentRequired terms in structuredContent; sign them and retry the identical call with the PaymentPayload at params._meta["x402/payment"]. Optional listing fields are written with the deed. px is 200 hex chars: 100 pixels, one palette index each.

Repaint pixels or update message/link on a block you own. Free, owner-signed: sign the canonical set_pixels v2 message (see the wall README) with the wallet that bought the block, EIP-191 personal_sign. ts is unix ms within 5 minutes of server time.
