  title: Polygon Options Contract Deep Dive
  summary: List an underlying's option contracts, snapshot the top contract, and pull its bars.
  description: >-
    An options analysis flow that drills from an underlying down to a single
    contract. The workflow lists option contracts for an underlying ticker
    filtered by type and expiration, takes the first matching contract,
    reads its full snapshot (greeks, implied volatility, open interest), and
    then pulls aggregate bars for that contract. The contract ticker
    resolved in the first step feeds the path parameters of the following
    two steps. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
