# Markets and Selections \ Only a set of specific markets and selections are available in BetBuilder events. \ Available events, markets and selections have a unique property: **`isBetBuilderSupported: True`**. \ First check should be done on event level if property is **true** or **false**. \ If event level property is **true** then next check should be done on market/selection level.\ If event level property is **false** then BetBuilder is not available even if on market level property is true.\ \ It is recommended to give a visual specifier on UI which events, markets and selections are available for BetBuilder. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
