Odds API by market / MLS
MLS Goal or Assist API
Live goal_or_assist 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 goal or assist is
Will this player either score or set up a goal. Roughly doubles a forward's chance versus the anytime market, and it is the standard way to price a creative midfielder who rarely finishes.
How we settle it. Graded at a threshold of one against the player's goals plus assists for the match.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 30 September 2026.
Books posting MLS goal or assist
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 goal or assist 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
16.5% of 1950 settled goal or assist legs hit (321 yes, 1629 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 1,950 YES legs out of 3,180 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 St. Louis City @ New York Red Bulls, 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.
