○Open: public page gives enough substance to understand the site $Paid: pricing, booking, ecommerce, subscription, or paid access is visible ADAds: visible ad load or ad-supported content ✦Pretty: notable design, copy, craft, or presentation ◆Pro: polished, finished-feeling, serious, or operationally mature ◇Niche: specific audience, workflow, or unusually focused use case ◉Human: personal, local, community, civic, handmade, or real-person signal !Suspicious: scammy, spammy, trust theater, finance fog, or credibility concern

A free, deterministic market-data API that mimics Alpaca, Alpha Vantage, and Polygon interfaces for development, CI, and demos.
