Odds API by market / MLB
MLB Batter Hits API
Live batter_hits 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 hits is
Hits by one batter, as a true Over/Under. The YES-style "to record a hit" and the N+ milestone rungs live on their own keys so bet types never mix under one market.
How we settle it. Graded against the batting stat group's hits column.
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 hits
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 hits 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.
43,732 batter hits outcomes settled in the last 4 days across 15 books. The 12 most recent:
| Player | Bet | Actual | Result |
|---|---|---|---|
| Alejandro Kirk | Over 1.5 | 2.0 | won |
| Alika Williams | Over 1.5 | 0.0 | lost |
| Brett Bateman | Over 1.5 | 0.0 | lost |
| Alejandro Kirk | Over 1.5 | 2.0 | won |

| Donovan Walton | Over 0.5 | 0.0 | lost |

Over/Under split, last 4 days
The Over won 39.5% of 21361 decided batter hits lines (8427 over, 12934 under). Computed from the settled rows themselves, scoped to MLB only.
Read off 23,072 Over legs out of 43,732 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 Cleveland Guardians @ Baltimore Orioles, 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.
