Unnamed service

Enriched quote for an x402 endpoint: probes it unpaid (never pays, SSRF-checked), decodes {price, asset, network, payTo}, then compares the USD price against the live Bazaar market for its category → {marketContext:{category, medianForCategory, cheaperThanMarket}}. Not just how much, but whether it's fair. Market context is best-effort; the decoded quote returns even if the Bazaar read fails. Neutral — our own endpoints are never featured.
