Only routes that answered a valid x402 402 at our census probe; the top three are checked again at answer time and one that answers goes first. Order: how well the route's own description matches your words, then distinct buyers of that exact route in 30 days and its calls (Coinbase CDP catalogue), paid in the last 7 days, input schema published, then lower price. Paid placement never changes this order; it shows only under sponsored.
