  title: CryptoCompare Exchange Discovery
  summary: List exchanges, read general info, then rank top exchanges for a pair.
  description: >-
    A venue-analysis flow that lists every integrated exchange and the pairs
    each exposes, reads descriptive metadata and ranking grades for all
    exchanges, and then ranks the top exchanges by 24-hour volume for a specific
    pair before reading the full-data envelope for that same pair. 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.
