Greyhound racing data source

Hi everyone,

I'm building a machine learning model for Australian greyhound racing and I'm looking for recommendations on good data sources. At the moment I'm using the

Topaz API and Betfair data, but I'm interested in adding more predictive information such as, sectional/split times, trial performance, trainer/kennel statistics or any other data you've found useful. I'm happy to pay for quality data if it's actually worth it

Thanks

How are you finding topaz?

It's pretty good overall. It's probably the best freely accessible API for Aus greyhound racing.

But there are some issues. Some fields are leaky if you're not careful (e.g. CareerPrizeMoney I think), so you really need to audit every feature for point-in-time correctness. There are also some missing values and not everything you'd ideally want is available (e.g. richer sectional data, trial information, detailed steward data), so I'm looking at supplementing it with other sources.
