Odds API by market / MLB
MLB Batter Strikeouts API
Live batter_strikeouts odds across every book that posts it, in one REST call — and, unlike any other odds API, every one of those outcomes settled against the official result once play ends.
No credit card. 1,000 requests / day on the free tier.
What MLB batter strikeouts is
Strikeouts by a hitter. Carried on its own key so it can never collide with the pitcher strikeouts market.
How we settle it. Graded against the BATTING stat group's strikeout column, never the pitching group's.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 8 September 2026.
Books posting MLB batter strikeouts
Measured live, not listed from a spec. Coverage moves — a book that has not put its board up yet will not appear until it does, which is exactly what this list is for.
Line shopping across all of them is one request — every book arrives in the same bookmakers array, not one call per book. Add ?bookmakers= to narrow it, or use /best-line for the best price per line already ranked.
Recently settled MLB batter strikeouts outcomes
These are real rows out of the API, not an illustration. Each one was a price on a board before the event and carries the actual figure it was graded against afterwards. No other odds API returns that last column — they stop at the price.

Hit rate, last 4 days
35.2% of 2609 settled batter strikeouts legs hit (918 yes, 1691no). Counted on the YES side only — books that price this two-way contribute their Over leg, not both. That is the base rate across the whole priced field, not a per-player figure.
Read off 2,609 YES legs out of 7,102 settled outcomes on this market. The rest are the Under side from books that price it two-way, which answers a different question.
Per-player hit rates and L5 / L10 / L20 splits live on /trends.
Live response
