Odds API by market / MLS
MLS Player Assists API
Live player_assists 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 MLS player assists is
Assists by one player, priced as milestone rungs (1+, 2+) rather than as an Over/Under. Books disagree about what counts as an assist more than they disagree about goals, so cross-book comparison matters here.
How we settle it. Graded at the rung's threshold against assists in the match's player statistics.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 16 August 2026.
Books posting MLS player assists
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 MLS player assists 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.
1,692 player assists outcomes settled in the last 4 days across 3 books. The 12 most recent:

Over/Under split, last 4 days
The Over won 5.4% of 261 decided player assists lines (14 over, 247 under). Computed from the settled rows themselves, scoped to MLS only.
Read off 440 Over legs out of 1,692 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.
