Every racing site publishes Cox Plate odds. This page does two other things: it shows what the Flemington market actually did this spring, measured from the bookmaker closing-line archive rather than remembered, and it lists what a race-day build needs working before Saturday 24 October 2026.
Run at Flemington in 2026, for this year only, while Moonee Valley is rebuilt. It is the first Cox Plate away from the Valley.
20 Flemington races over 2 meetings are in the closing-line archive, from 12 September 2026 to 3 October 2026, priced by 14 served bookmakers. The closing favourite won 20% of the 20 races with a final result (4 wins) and finished in the first three in 45%, at an average closing price of $3.04.
Of 223 runners with a qualifying price path, 7% firmed by a fifth or more between their opening and closing price and 26% drifted by a quarter or more; the median runner closed within 7.7% of where it opened.

Method: for each runner, the median across served bookmakers of its closing win price divided by its opening price, where the open is the earliest archived price up to an hour before the jump, each bookmaker observed the runner at least three times over at least twenty minutes and held a closing line, at least three bookmakers qualify, and the race has a final result. The favourite is the runner with the lowest median closing price. Same rules as the weekly market report; measured 19 Oct 2026 07:32 UTC. These are bookmaker prices, not exchange prices.
The same rows are yours through /v1/racing/closing-lines for any race the
archive holds, every served bookmaker's open and close per runner.
In the order you will reach for them.
| Endpoint | What it gives you | Cost |
|---|---|---|
/v1/racing/acceptancesThe field |
Every runner, barrier, jockey, trainer and weight as Racing Australia publishes it — about two days out, before any bookmaker has framed a market. Carries runner_ref, and race_id once a market exists. | 2 credits |
/v1/racing/eventsThe card and the real jump time |
The authoritative start_time. Do not hardcode the post time from a news article — read it here once the meeting loads, because advertised times move. | 1 credit |
/v1/racing/next-to-goThe priced board |
Every bookmaker's win and place price per runner, with per-quote freshness. This is the one to build the board on. | 2–4 credits |
/v1/racing/best-oddsBest price per runner |
The comparison, already computed, with the book that holds it. | 3 credits |
/v1/racing/changesWhat moved, instead of polling |
The change feed. On a day when you want to see every move, this costs far less than re-reading the whole board on a timer. | 2 credits |
/v1/racing/resultsThe settled result |
Finishing positions and status once the race is official. | 2 credits |
/v1/racing/closing-linesWhat the market closed at |
The settled final price per runner — the benchmark for judging anything you did. | 5–20 credits |
How far ahead your key can read the card is set by your plan, and it decides when the
Cox Plate field first becomes visible to your code. The windows below assume a
mid-afternoon jump; the authoritative start_time comes from
/v1/racing/events once the meeting loads.
| Plan | Allowance | Rate limit | Reads ahead | Field visible from |
|---|---|---|---|---|
| Free $0 | 3,000 | 30/min | 24h | Friday 23 October, 4pm |
| Hobby $9 | 7,500 | 60/min | 24h | Friday 23 October, 4pm |
| Standard $29 | 75,000 | 200/min | 48h | Thursday 22 October, 4pm |
| Plus $49 | 140,000 | 500/min | 168h | Saturday 17 October, 4pm |
| Business $99 | 300,000 | 750/min | 168h | Saturday 17 October, 4pm |
| Platform $199 | 1,500,000 | 1000/min | 168h | Saturday 17 October, 4pm |
| Scale $249 | 5,000,000 | 2000/min | 168h | Saturday 17 October, 4pm |
A free key reaches 24 hours ahead, Standard 48, Plus and above
168. Every response states your own ceiling in X-Horizon-Hours;
asking past it is a 403 that names the tier which reaches further, and it costs no credit.
| Plan | Credits/month | Sustainable interval, all month | Hours at a 30-second poll |
|---|---|---|---|
| Free | 3,000 | every 29m | 12h |
| Hobby | 7,500 | every 12m | 31h |
| Standard | 75,000 | every 69s | 312h |
| Plus | 140,000 | every 37s | 583h |
| Business | 300,000 | every 17s | 1250h |
| Platform | 1,500,000 | every 3s | 6250h |
| Scale | 5,000,000 | every 1s | 20833h |
The cheap fix is to stop polling: /v1/racing/changes
returns what moved since your last read.
/v1/racing/acceptances?date=YYYY-MM-DD carries every runner, barrier,
jockey, trainer and weight before a bookmaker has framed a market. Load it, diff it
daily, and expect scratchings.X-Horizon-Hours on a live
response rather than assuming./v1/racing/results for the settled finish, then
/v1/racing/closing-lines for what the market closed at, which is the only
honest benchmark for anything your model did. Then run it again on
The Everest day and Caulfield Cup day and Cup day.A free key is 3,000 credits a month and needs no card. That is enough to build and test everything above; the horizon is the part to think about before race week.
