Data quality, measured

Racing coverage and feed freshness

Australian races over the trailing 7 days, measured 1 Oct 2026 12:38 UTC and recomputed every 30 minutes. Degraded now: none.

"Time since last read" is how old our last successful read of that bookmaker was, over the last 24 hours. It is not the age of the price itself — capture is change-only, so a price can be minutes old while the read confirming it is seconds old. The per-book price ages, the books-per-race distribution and the SQL behind every figure are on the coverage report. New Zealand: 104 races from 12 books in the same window.

Results completeness

Races from 2026-09-25 to 2026-10-01. Of the 1,197 races that have a results source, 1,178 are settled (98.41%), 9 are pending and 10 are overdue. 262 more races have no results source yet — they are counted here, not hidden.

Read from GET /v1/racing/results/coverage, the same endpoint a customer calls.

Closing-line archive

1,540,903 rows across 42,502 races from 14 bookmakers, 2026-08-04 to 2026-10-01. 84.68% of rows are a genuine closing line. Of the 10,821 Australian and New Zealand races a result can exist for, 94.68% carry one.

Rows the archive flags about itself — flagged, not silently dropped: 13,401 where one meeting may have been split under two venue spellings, 410 with a suspect runner name, and 9,145 for runners the result marked scratched (hidden from /v1/racing/closing-lines by default). These flags catch known shapes of bad row. They cannot catch a bookmaker feed that was wrong at source — see the limits below.

Read from GET /v1/racing/closing-lines/coverage.

Sports price sanity check

Every 15 minutes, each bookmaker's head-to-head price on each game is compared with the median of the other bookmakers quoting that game. A price more than 20% away is flagged as a likely stale or bad quote. Games need three or more books to be checked.

Read from GET /v1/data-quality/audit/latest. This is a consensus check, not a comparison with each bookmaker's own site, and it covers sports only.

Odds API availability

The API's /health endpoint is probed every ten minutes, monitored since 2026-07-03. 100.0% over 7 days (1,008 checks) · 99.98% over 30 days (4,320 checks) · 99.96% over 90 days (19,386 checks). These are observed measurements, not a contractual SLA. Every surface, the blind periods and the method are on the status page.

Check it yourself

No key needed: /data-quality.json (this page as JSON), /coverage-report.json and /uptime.json. With any key, 1 credit each: GET /v1/racing/results/coverage and GET /v1/data-quality/summary; the archive's own measurement is on the plans that include the archive. Every racing quote also carries its own age_seconds and last_update, so you can gate on freshness per bookmaker in your own code.
