Cost: 3 credits. The best win, place and tote price for every runner in the next races, with the bookmaker offering it and a deep link to their race page.

market_percentage is the sum of implied probabilities at the best available price. Under 100 means the best prices across books beat the field — a cross-book arbitrage. Any single book's market is always over 100.

price_spread_pct per runner is how much better the best price is than the worst currently quoted: how much a punter loses by not shopping around.

Win and place coverage are counted separately. books_quoting_win is the number of bookmakers with a WIN price on that runner and books_quoting_place the number with a PLACE price. They are not the same set — a book can quote the win and not the place on the same runner — so a place bet sized off a win-market count is sized off the wrong number. books_quoting is retained unchanged for existing clients and equals books_quoting_win; read the explicit names in new code. books_compared, at race level, is the number of distinct books contributing any win price to the whole race.

⚠️ best_tote is not comparable to best_win. A pre-race tote dividend is an estimate that moves as the pool fills, and taking the highest across books and products is upward biased by construction — the noisiest estimate wins. Greyhound pools are thinnest and swing hardest: measured 2026-08-15, greyhound tote-to-fixed ratios reached 8.8x on betright and 9.9x on tabtouch, against averages near 1.0 for horse and harness. A tote figure far above the fixed price is usually a thin pool, not an edge. Settle against a FINAL dividend, and read the product code — PROV is indicative, SP/MIDDIV/RD+/BT+SP are named products.

The comparison covers the Australian fixed-odds bookmakers, on New Zealand races as well as Australian ones. Not every book quotes New Zealand, so an NZ race is compared across fewer books than an AU race; the live per-country book counts are published at https://puntersedge.online/coverage-report. Betfair Exchange prices are withheld pending a Betfair Exchange data licence, and non-AU reference books are excluded because an Australian punter cannot bet them — so betfair_ex_au never appears as a best_win bookmaker, and market_percentage is the fixed-odds market rather than an exchange-inclusive one.

Hong Kong (country=HK, feature_requests #29, 2026-09-09). Sha Tin and Happy Valley are compared across whichever Australian books quote the meeting — win and place, the same best_win / best_place shape as an Australian race. PRICES ONLY: no results, no form, no race conditions, no runner_ref — horse_ref alone is present, because it is derived from the runner's name and needs no Racing Australia read. Unlike the rest of the foreign card this is a real cross-book comparison rather than one book against itself, but it is a smaller panel than an Australian race and only exists on the HKJC's nights — Happy Valley on Wednesday evenings, Sha Tin on Saturday or Sunday afternoons (AEST).

Scratched runners are never priced here. They appear in scratchings only, and are left out of market_percentage.

Placeholder prices are kept out of the best line (since 2026-09-10). A quote of $21 or more that is at least 4x the median of three or more other books for the same runner is treated as a placeholder, not a price: it is excluded from best_win / best_place, market_percentage and price_spread_pct, and listed on the runner as suspect_win / suspect_place (bookmaker, price, consensus) so nothing is hidden. A book that has not priced a runner yet can publish $101 against a $9 field; before this that was the best price. The same treatment, with a reason on the entry, covers a book quoting before the race's newest scratching (pre_scratching), a book whose whole win book sums under 95% (book_under_round), and since 2026-10-20 a book that has not re-priced the race for an hour while the other books have, on a runner where it is 1.6x or more the median of eight or more others (book_not_repriced, with consensus and behind_market_s).

Every published price carries its own age. best_win, best_place and best_tote each include last_update, age_seconds, stale and refresh_tier, because the book with the best price is not always the book that answered most recently. best_win and best_place both carry the offering book's race-page source_url. On Plus and above both also carry betslip_url, the runner-level betslip link of that same book - null when the book has no such route, and absent on plans below Plus. See the table below. Race level, data_age_seconds is the oldest of those winning quotes and stale_bookmakers names any past its own refresh_tier threshold (120s on live, 1800s on card; each published quote carries its own tier, and a Betr quote 30-180 minutes from the jump is card on a live race — see /v1/racing/next-to-go for what the tiers mean). Responses are cached for 20s and say so via cached / cache_age_seconds; ages are recomputed at serve time, so a cached payload reports its real age rather than the age it had when it was stored.

Same Race Multi legs (best_top2, best_top3, best_top4, since 2026-09-05). The best price across books for the runner to finish in the first two, three or four, in the same shape as best_place (price, bookmaker, source_url, age fields) plus books_quoting, the number of books offering that leg. Present only when at least one book quotes the leg: Ladbrokes, Neds and PointsBet carry all three, Sportsbet where its racecard offers them. Every published leg satisfied win >= top2 >= top3 >= top4 > 1.0 at its source.

Runner-level betslip links (betslip_win_url, betslip_place_url, betslip_app_only). Where source_url opens the book's race PAGE, these open the book's BETSLIP with this runner already selected. Plus and above (since 21 September 2026): the betslip fields are served on Plus, Business, Platform and Scale, and a Standard or Hobby key issued before that date keeps them - a key never loses what it was sold. On every other plan the fields are simply absent, exactly as on a book with no route; source_url, the race-page link, is on every plan and is unaffected. Coverage, honestly:

Every other bookmaker has no such route and carries none of these fields. betslip_app_only is true for Ladbrokes and Neds: in a desktop browser those URLs redirect to the app-download page, so send them to a phone with the app installed, or fall back to source_url. Measured 2026-09-03. The Ladbrokes pattern is vendor documented; the Neds one is inferred from it (same platform, same entrant ids) and has not been tap-tested on a Neds install.

These routes are read from the bookmakers' own site code. None of them is published or supported by the bookmaker, so any can change without notice. A daily automated check loads a live Unibet link and a live TAB link in a real browser and confirms the betslip populates; when a book fails that check its betslip fields go null until it passes again, so a broken route degrades to "no link" rather than sending a member to a dead page. Ladbrokes and Neds cannot be checked this way - a headless browser cannot open a native app - and ship on the vendor's documentation instead.

The fields are absent on a book that has no link, exactly as source_url is; treat absent and null alike as "no betslip link". Nothing about source_url changed.

Like source_url these are plain URLs, and extra query parameters you append are passed through untouched. A link that opens a native app leaves the browser, so cookie-based attribution set by your own site does not travel with it.

Your own links (source_link and betslip_link on every quote object, since 2026-10-14, Plus and above). Store your bookmaker link templates once with PUT /v1/link-templates (for example your affiliate tracking link per bookmaker, with {url} where the bookmaker's URL goes) and each quote also carries a ready-made twin of its URLs, built through them: put the *_link value on your page. A twin is absent where there is nothing to link, and an account with no stored templates sees none. The *_url fields are unchanged.
