Double odds scraper

Scraper controls

Use an active-meeting shortcut or enter the date and venue code directly. For a single matrix, the scraper will clamp the race number to the valid Double range.

Meeting and pool metadata
The scraper keeps meeting-level context visible so you can verify the source meeting, leg pair, and pool money before reading the matrix.

How to use this page
Use active shortcuts first
The active-meeting chips populate the date, venue, and likely next race. That reduces input error when the live meeting code differs from the alias you expect.
Single mode is faster
Use single mode for quick inspection. All mode issues one upstream request per race pair, so it is heavier and best used when you need full-card coverage.
Validate freshness before reading odds
Check the last update time, sell status, and investment before acting on the matrix. The page is a structured mirror of upstream data, not an independent market source.
