Odds API by market / NBA
NBA 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 NBA assists is
Assists recorded by one player. Sensitive to teammate shooting, which is why it disagrees across books more than points does.
How we settle it. Graded against the box score's assists column.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 17 October 2026.
Books posting NBA 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 NBA 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.
3,628 assists outcomes settled in the last 4 days across 10 books. The 12 most recent:
| Player | Bet | Actual | Result |
|---|---|---|---|
| Luka Doncic | Over 6.5 | 2.0 | lost |
| Luka Doncic | Under 6.5 | 2.0 | won |
| Austin Reaves | Over 5.0 | 3.0 | lost |
| Nikola Jokic | 10+ Assists | 8.0 | lost |
| Nikola Jokic | 11+ Assists | 8.0 | lost |
| Nikola Jokić | 10+ Assists | 8.0 | lost |
| Nikola Jokić | 11+ Assists | 8.0 | lost |
| Austin Reaves | 10+ Assists | 3.0 | lost |

| Austin Reaves (LAL) | To Record 10+ Assists | 3.0 | lost |
| Austin Reaves (LAL) | To Record 4+ Assists | 3.0 | lost |
Over/Under split, last 4 days
The Over won 37.9% of 198 decided assists lines (75 over, 123 under, 5 push). Computed from the settled rows themselves, scoped to NBA only.
Read off 263 Over legs out of 3,628 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 Boston Celtics @ Detroit Pistons, 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.
