Odds API by market / MLB
MLB Pitcher Outs Recorded API
The pitcher_outs board is not posted right now. This page keeps the last measured window — 426 settled outcomes — and reactivates on its own the first build after books post the market again. The endpoint, the response shape and the free tier work today.
No credit card. 1,000 requests / day on the free tier.
What MLB pitcher outs recorded is
Outs recorded, which is innings pitched multiplied by three. Books quote outs rather than innings because a two-thirds inning is not a clean line.
How we settle it. Graded against innings pitched in the box score, converted to outs.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 27 October 2026.
Books that last posted MLB pitcher outs recorded
Measured on the last slate that carried it, 27 October 2026. When books post it again, this list rebuilds from whichever ones actually do.
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 outs recorded 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.
426 pitcher outs recorded outcomes settled in the last 4-day window it was posted across 23 books. The 12 most recent:

Over/Under split, last posted window
The Over won 35.4% of 189 decided pitcher outs recorded lines (67 over, 122 under). Computed from the settled rows themselves, scoped to MLB only.
Read off 212 Over legs out of 426 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 Milwaukee Brewers @ Tampa Bay Rays while it was posted, 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.

}The response shape is the-odds-api compatible — events, bookmakers, markets, outcomes — so migrating is usually a base URL change.
