Get the published editorial ranking ("Best {Category}") for a category. Ordering basis: computed editorial score ONLY (verified capability coverage, evidence verification rate & freshness, agent readiness, data completeness — weights published at /api/methodology). Tier is NOT a ranking input for this tool; positions are never sold. Rankings are published snapshots (monthly schedule; manual publishes are marked) — stable between recomputes and citable. Each entry carries { position, rank (0..1), slug, name, score (0-100), breakdown (raw 0-100 per dimension), tier (annotation only), houseProduct (true = built by Revuo's founder — same formula as everyone, disclosed machine-readably), unverified, verifiedAt }. unrankedCount + unranked[] name the category products that failed an eligibility gate, with reasons. Response: { category, computedAt, methodologyVersion, methodologyUrl, trigger, entries[], unranked[] }. Errors: { error: { code: 'not_found', ... } } — also returned when a category has no published ranking yet.
