Betfair Fees 

In addition to subscriptions, API customers should be aware of the Betfair transaction and data request fees that apply based on usage.

Most Betfair customers are only charged commission on their net winnings in a market, as set out in more detail on the Betfair Charges page. However, customers who place more than 1000 bets in an hour may also be charged a transaction fee depending on the number of bets placed and the amount of commission they have already paid.  In addition, customers who make more than 20 data requests in any one second may also be charged a fee depending on the number and type of data requests made and whether they were also generating matched bets as opposed to just reading data.

For further information on transaction and data request fees, please see the Betfair Charges page.
