  description: >-
    Cross-asset market data research surface. Pulls ticker reference,
    aggregate bars across stocks/options/indices/forex/crypto, and
    snapshots into a single composed workflow. Lead operation: List
    Ticker Symbols across asset classes. Self-contained Naftiko
    capability covering a Polygon cross-asset research surface.
