Call this when you have a need in words and want one service to call rather than a list to read: it is the free ranking step between searching and paying. Pass the need as q, plus any category, network, price cap or verification requirement, and get up to 20 ranked recommendations with the basis each one placed on. Ranking is mostly per-service reliability (live status, verification, uptime, response time), x402 compliance, and price in USD, with a small (about 10%) weight on measured on-chain settlement traction that can never dominate those three. The response carries ranking_version (currently 3), need_blind_ranking (true when no q was given, so the order is global quality rather than your need), and a units map holding every scoring caveat in full: the compliance cap, the pro-quota rule for shared payout addresses, renormalization, the $10 volume floor, and the single-buyer discount. Read units before comparing scores across generations.
