What is read-only Betfair API access?

Read only Betfair API access using the live application key is not permitted.

Ready only access refers to access to the API that reads/collects Betfair price/market data without the intention to place bets on the Betfair Exchange.

We do not provide specific guidelines relating to how we monitor read-only access.  However, if your intention is not to place bets on the Betfair Exchange when interacting with the Betfair API, you should use the delayed rather than the live application key to avoid access restrictions, including deactivation of your live application key.
