Betfair API is 100% free for customers with a lot of code examples in various languages. Tabcorps TABStudio - http://studio.tab.com.au/ http://studio.tab.com.au/ (You need to register as a tabcorp customer but it's "free"). Its basically a JSON REST API NZ TAB have their batch mode, at filebet.tab.co.nz, which is nothing more than a file upload system. The ATG, and the other Scandinavian totes provide coupon upload systems (where you generate a coupon file with your selections in it, using third party software), but if you win they will end up banning you. Most providers keep their APIs hidden or require signing NDAs or other types of contracts, I'm referring to companies like Amtote, Churchill Downs, PMU, BetFred, PGI, LeTurf etc Usually they're quite surprised when you contact them about doing "integration work", a lot of the APIs are designed for retailer shops to integrate with. For example, I've done some integration work with BetFred, where my client never wants to cancel a bet (placed at the last possible moment), however in order to pass their integration tests, I have to fully support cancelling a wager, just like any retail shop would. On a side note, I have used (at least one of) the APIs shaunray was referring to that he had worked on.
