Odds API by market / MLB
MLB Total Runs API
Live totals 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 total runs is
Over/Under on combined runs. Alternate totals and per-team run totals ship in the same response; a team total carries the team name in the market description.
How we settle it. Settled against the combined final score, or one team's runs for a team total.
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 total 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 total 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.
31,743 total runs outcomes settled in the last 4 days across 26 books. The 12 most recent:
| Bet | Actual | Result |
|---|---|---|
| Over 8.5 | 8.0 | lost |
| Under 8.5 | 8.0 | won |
| Over 9.0 | 8.0 | lost |
| Under 9.0 | 8.0 | won |
| Over 0.5 | 0.0 | lost |
| Over 0.5 | 0.0 | lost |
| Under 0.5 | 0.0 | won |
| Over 8.5 | 8.0 | lost |
| Under 8.5 | 8.0 | won |
| Under 0.5 | 0.0 | won |
| Over 1.5 | 0.0 | lost |
| Under 1.5 | 0.0 | won |
Over/Under split, last 4 days
The Over won 51.8% of 14936 decided total runs lines (7732 over, 7204 under, 284 push). Computed from the settled rows themselves, scoped to MLB only.
Read off 15,883 Over legs out of 31,743 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 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.

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