Why this is cheaper
sec-api.io puts 10-K/10-Q section extraction on its Business tier at $239/month, and its $55/month entry tier does not include extraction at all (their pricing page, checked 15 Aug 2026). Intrinio starts at $150/month for SEC-derived fundamentals.
Those are subscriptions: you pay the floor whether you run one job or a thousand. Here the same year-over-year diff is $0.50 and the floor is zero. You would need about 480 diffs a month before this costs what the $239 tier costs.
