Odds API by market / MLB

MLB Hits + Runs + RBIs API

Live batter_hits_runs_rbis 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 hits + runs + rbis is

The H+R+RBI combo, summed into one line. A batter can move it twice on one swing by driving himself in.

How we settle it. Graded against the sum of the three batting columns.

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 hits + runs + rbis

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 hits + runs + rbis 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.

55,420 hits + runs + rbis outcomes settled in the last 4 days across 12 books. The 12 most recent:

Over/Under split, last 4 days

The Over won 37.9% of 23236 decided hits + runs + rbis lines (8808 over, 14428 under). Computed from the settled rows themselves, scoped to MLB only.

Read off 24,741 Over legs out of 55,420 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.

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