Odds API by market / MLB
MLB Pitcher Outs Recorded API
Live pitcher_outs 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 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 6 October 2026.
Books posting MLB pitcher outs recorded
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 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.
866 pitcher outs recorded outcomes settled in the last 4 days across 22 books. The 12 most recent:
| Player | Bet | Actual | Result |

| Cam Schlittler | Under 17.5 | 13.0 | won |

Over/Under split, last 4 days
The Over won 35.3% of 445 decided pitcher outs recorded lines (157 over, 288 under, 2 push). Computed from the settled rows themselves, scoped to MLB only.
Read off 449 Over legs out of 866 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 Los Angeles Dodgers @ Atlanta Braves, 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.
