netkeiba JRA Racing — Race Cards, Results & Payouts

What it does: Returns Japan's central (JRA) horse racing in English from netkeiba: the full result and every payout once a race is run, or the race card with odds before it.

You enter: A 12-digit netkeiba race ID, e.g. 202603020712, or a race day like 20260726.

You get: One row per race: venue, distance, surface, going; finish order with jockey, time, win odds, trainer, body weight; every payout from win to trifecta. Before the race: runners, jockeys, weights, current odds, favourite rank.

Price: $0.02 per race — a whole race day is up to 12 races, each charged. +$0.002 per horse if you also want one row per horse (off by default). A race with no data = no charge.

Example: enter 202603020712 → Fukushima race 12 · dirt 1,150 m · 16 runners · winner Royal Spire at 4.0 odds · win pays ¥400 · trifecta pays ¥12,340

Pricing — $0.02 per race

Event	Price	When
Race analyzed (result or card)	$0.02	Per race
Individual horse	$0.002	Only if you enable Include individual horses

A default run (1 race) costs $0.02. Every race in the run is charged, so a whole race day in date mode is up to 12 races at $0.02 each by default (raise maxRaces and it charges for those too). You are never charged for a race that returns no data. You pay per race; there is no fixed monthly fee.

Before a race is official the record is a race card instead: type: "race_card", status: "not_run_yet", and an entries list with bracket, horse number and name, sex/age, weight carried, jockey, trainer, current win odds and favourite rank.

Use cases

• Prediction models & backtesting — results with odds, payouts and body weights, keyed by a stable race-id scheme
• International racing coverage — JRA data in English for tools, bots and dashboards (Japan's top races increasingly feature in world rankings)
• Betting analytics — payout pools per race for takeout/value analysis across venues and distances

Notes & limits

• Covers JRA (central) racing via en.netkeiba.com; local (NAR) racing is not included in v1
• Results appear about 10 minutes after each race; before that the actor returns the race card instead (type: "race_card", status: "not_run_yet"), charged the same $0.02
• If netkeiba has no race under an id, you get a row with status: "no_data", empty results/entries and no charge — the run still succeeds. A run only fails when the site cannot be read at all
• A raceIds entry that is not 12 digits is skipped with a warning in the log that shows the shape (202603020712 = year 2026, venue 03 Fukushima, meeting 02, day 07, race 12); the remaining ids still run
• Read-only and throttled (~1 request / 1.5 s). No login, no personal data, nothing stored between runs

If something goes wrong

• Wrong number or a failed run? Open a ticket on the Issues tab. I read every one and reply within 2 business days (Japan time).
• You never get a fake "empty" result. If the site can't be read, the run fails and says so.
• No results = no charge. You only pay for results you actually get.
• Checked every week. An automatic test runs this tool weekly; if the site changes, I fix it.
• Public pages only. No login, no personal data, and it goes easy on the site.
