Odds API by market / MLB

MLB 2+ Home Runs API

Live batter_2plus_home_runs 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 2+ home runs is

A multi-homer game. The longest price on the everyday board at most books.

Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 15 September 2026.

Books posting MLB 2+ home runs

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 2+ home runs 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

0.6% of 4605 settled 2+ home runs legs hit (26 yes, 4579no). 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 4,605 YES legs out of 4,975 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 Athletics @ Tampa Bay Rays, 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.
