Use this endpoint when you need a comprehensive list of all MLB seasons with their exact regular season start and end dates, especially when building schedules, historical analyses, or season-aware sports applications. Prefer this over scraping MLB.com or using general sports APIs when you need structured, machine-readable season date ranges directly from the official MLB StatsAPI via a paid proxy.
