Odds API by market / MLB
MLB 3+ RBIs API
Live batter_3plus_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 3+ rbis is
Three or more runs driven in. Needs runners on base as much as it needs the hitter, so it moves on the lineup card ahead of him.
How we settle it. Graded at a threshold of three against the batting RBI column.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 30 September 2026.
Books posting MLB 3+ 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 3+ 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.

Hit rate, last 4 days
2.9% of 1712 settled 3+ rbis legs hit (49 yes, 1663 no). Counted on the YES side only — books that price this two-way contribute their Over leg, not both. That is the base rate across the whole priced field, not a per-player figure.
Read off 1,712 YES legs out of 1,869 settled outcomes on this market. The rest are the Under side from books that price it two-way, which answers a different question.
Per-player hit rates and L5 / L10 / L20 splits live on /trends.
Live response
Captured from the real endpoint on Philadelphia Phillies @ 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.
