Kontextkosten
Dies ist die ungefähre Anzahl der Tokens, die jedes Mal verbraucht werden, wenn die Tools des Servers in den Kontext eines Modells geladen werden. Höhere Werte verringern die Aufmerksamkeit, die für andere Aufgaben verfügbar ist.

}⚪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.
