Size-the-room: top N holders of a Polymarket market ranked by skill_score, with per-holder ghost-fill risk. POST {condition_id, n?}. The pre-trade check for trading and market-maker agents — answers 'who am I about to be against, and will their fills actually settle?'

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
