Use this endpoint to discover which trading dates are available in the dataset before querying other market endpoints. Dates are listed in reverse chronological order. Each entry includes the closing ASI value and a convenience label (today, yesterday, latest, or previous) for the most recent entries. This is useful for building date pickers or validating user-supplied dates before making downstream requests.
