The x402 leaderboard's top seller made $1,714 this week. Seventeen of the top 25 are one-buyer shops.

I pulled the live top-25 Base x402 seller leaderboard (7-day window, 2,112 sellers scanned) and read the fields nobody talks about: uniqueBuyers, topPayerUsdShare, concentration. The visible market is $4,580/week, rank 1 is 37% of it at $0.02 per call, and 17 of 25 entries are single-payer shops. What that means for pricing, vetting buyers, and which shape of success to aim for.
