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 14 November 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.

Hard Rock Bet

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.

13,595 goal or assist outcomes settled in the last 21 days across 7 books. The 12 most recent:

Over/Under split, last 21 days

The Over won 15.2% of 479 decided goal or assist lines (73 over, 406 under). Computed from the settled rows themselves, scoped to MLS only.

Read off 815 Over legs out of 13,595 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 FC Cincinnati @ Orlando City SC, 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.
