Odds API by market / MLB
MLB 3+ RBIs API
The batter_3plus_rbis board is not posted right now. This page keeps the last measured window — 206 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 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 27 October 2026.
Books that last posted MLB 3+ rbis
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 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.
206 3+ rbis outcomes settled in the last 4-day window it was posted across 5 books. The 12 most recent:

Hit rate, last posted window
0% of 201 settled 3+ rbis legs hit (0 yes, 201 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 201 YES legs out of 206 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 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.
