  title: CryptoCompare Coin Price Snapshot
  summary: Resolve a coin, read its live price, full ticker, and daily OHLCV history.
  description: >-
    An analyst flow that builds a complete picture of a single cryptocurrency.
    It first confirms the coin exists in the CryptoCompare coin list, then reads
    the latest aggregated price against one or more quote currencies, pulls the
    full ticker envelope (24h volume, high, low, change, market cap), and finally
    retrieves daily OHLCV candles so the live snapshot can be placed in
    historical context. Every step spells out its request inline, including the
    api_key, so the flow can be read and executed without opening the underlying
    OpenAPI description.
