Odds API by market / MLB

MLB Pitcher Strikeouts API

Live pitcher_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 pitcher strikeouts is

Strikeouts recorded by a starting pitcher. The deepest baseball prop market, and the one with the widest alternate ladder — books post both a half-point Over/Under and a full set of N+ rungs.

How we settle it. Graded against the pitching stat group. Deliberately distinct from batter strikeouts, which reads the batting group — one key for each so a strikeout prop can never grade against the wrong side of the plate.

Books posting MLB pitcher 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 pitcher 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.

11,254 pitcher strikeouts outcomes settled in the last 4 days across 17 books. The 12 most recent:

Over/Under split, last 4 days

The Over won 47.3% of 3660 decided pitcher strikeouts lines (1732 over, 1928 under, 23 push). Computed from the settled rows themselves, scoped to MLB only.

Read off 3,720 Over legs out of 11,254 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.

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.
