The winner's claim of one face of the Earth's mesh for one term: for one term the face is yours alone, the gavel says so and a public chain proves it. Bid first, free, at POST /api/bid {addr, amount_degrees, salt}; after the gavel GET this route with the receipt's addr, start, amount and salt; a winner pays the clearing price here — a dollar at the reserve, USDC on Base — and the lease issues.
