Momentum radar for the x402 seller ecosystem
Momentum radar for the x402 seller ecosystem - which sellers are heating up, graded for wash-trade resistance. Reads the hourly on-chain leaderboard (real Base USDC settlements) and adds per-seller signals the raw board doesn't have: organicScore (uniqueBuyers/callsSettled - 1000 calls from 2 buyers smells like self-dealing, 1000 from 400 is organic demand) and avgTicketUsd.
