J1 League Double Chance API
The double_chance board is not posted right now. This page keeps the last measured window — 72 settled outcomes — and reactivates on its own the first build after books post the market again. The endpoint, the response shape and the free tier work today.
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 19 September 2026.
Books that last posted J1 League double chance
Measured on the last slate that carried it, 19 September 2026. When books post it again, this list rebuilds from whichever ones actually do.
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 posted window
66.7% of 72 settled double chance legs hit (48 yes, 24 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.
Live response
Captured from the real endpoint on Kashiwa Reysol @ Machida Zelvia while it was posted, 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.
