Ranking is by measured probes only. No one can pay for placement. Every ~30 min we call each service unpaid (we never pay or settle) and record: up (HTTP <500), valid HTTP 402 with x402 payment requirements, whether the price/network/payTo match what Coinbase Bazaar advertises, and latency. Score 0-100 = uptime 25 + valid-402 rate 35 + price/network match 25 + latency 15. Sample: top 437 hosts by Bazaar 30-day calls (one URL per host), refreshed daily; 437 probed so far.
