Odds API by market / J1 League

J1 League Asian Handicap API

Live spreads 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 asian handicap is

The goal handicap. Quarter-goal lines split the stake across two handicaps, so a single outcome can half-win or half-lose.

How we settle it. Settled against the 90-minute goal margin.

Books posting J1 League asian handicap

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 asian handicap 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

50% of 222 settled asian handicap legs hit (111 yes, 111no). 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.

Read off 222 YES legs out of 260 settled outcomes on this market. The rest are the Under side from books that price it two-way, which answers a different question.

Per-player hit rates and L5 / L10 / L20 splits live on /trends.
