Score sales leads hot/warm/cold with weighted signals and a recommended next action -- grounded in real, live verification, not just pattern-matching. Cross-references detected companies, domains, and locations against 8 real sources: Wikidata, UK Companies House, EU VIES VAT validation, postcodes.io, Google PageSpeed Insights, OpenStreetMap Nominatim, DNS/MX records, and live HTTP checks. Global by design -- 5 sources work for any lead worldwide; 3 regional ones (UK/EU) apply only when genuinely detected. SPENDS your balance -- requires authentication (OAuth). Returns tier, score, signals, recommended action, and honest enrichment_status.
