What does on-chain demand quality look like across x402 sellers?

What the measured evidence supports

Of 1037 x402 sellers validated on-chain on Base, 289 show distributed (healthy) demand, 238 show concentrated (whale-led or intermediated) demand, and 7 show self-dealing patterns; 503 have too little on-chain activity to classify. These four buckets account for all 1037. Descriptive on-chain fact, an indicator — never an accusation.
