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.

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 16 August 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.

2,042 goal or assist outcomes settled in the last 4 days across 5 books. The 12 most recent:

Over/Under split, last 4 days

The Over won 12.3% of 244 decided goal or assist lines (30 over, 214 under). Computed from the settled rows themselves, scoped to MLS only.

Read off 361 Over legs out of 2,042 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 Portland Timbers @ Chicago Fire, 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.
