The first price each book showed for each market on this fixture, its opening line. Requires the Scale plan or above, with the same 14-day-or-everything split as the series endpoint (an older fixture on Scale is a 403 PLAN_REQUIRED naming business). A market with nothing recorded is returned with status: not_recorded rather than left out of the list.
