Odds API by market / J1 League
J1 League Double Chance API
Live double_chance 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 J1 League double chance is
Two of the three results in one bet — home or draw, away or draw, or either team to win. The standard way to back a side in a league where draws are common.
How we settle it. Settled off the final score against whichever pair of results the outcome covers.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 17 October 2026.
Books posting J1 League double chance
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 J1 League double chance 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
62.8% of 1437 settled double chance legs hit (902 yes, 535 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.
Per-player hit rates and L5 / L10 / L20 splits live on /trends.
