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 16 August 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.
9,827 batter strikeouts outcomes settled in the last 4 days across 4 books. The 12 most recent:

Over/Under split, last 4 days
The Over won 34.2% of 3221 decided batter strikeouts lines (1101 over, 2120 under). Computed from the settled rows themselves, scoped to MLB only.
Read off 3,486 Over legs out of 9,827 settled outcomes on this market. The rest are Unders and milestone legs (“1+”, “2+”) that some books price here too, and a threshold rung is not an Over.
A few days of one market describes a few days — it is not an edge. Pull the full history through /exports/resolved-props for a sample worth modelling on.
Live response
Captured from the real endpoint on Boston Red Sox @ Pittsburgh Pirates, trimmed to one book and three outcomes so the shape stays readable. The full response carries every book and every line, alternates included, in the same call.
