Available on Live Plus only

Previews for the races about to run, written from the field and its form before the off, over the next 1 to 48 hours.

Authenticate with your key in the X-API-Key header, or ?key= if your tool cannot set one — see Authentication. Works with sandbox keys inside the sandbox data window.

Browser code exposes whatever key it ships with — use a sandbox key for prototypes and proxy live keys through your own server in production.
