# Calculate-filter

Used this endpoint to get the odds and fair probabilities of the Custom Bet, and **determine which Custom Bet combinations are viable.**

Market and outcome elements will contain an extra "conflict" attribute, which will indicate whether specific markets and outcomes conflict with the current selections or not. The endpoint will return a response that contains the new "conflict" attribute in all the available selections for the selected markets.

{% hint style="success" %}
**Best Practice:**

* Conflict Handling: Use the "conflict" attribute to filter out or visually distinguish conflicting selections in the UI. This helps prevent users from creating invalid bet combinations.
* Selected Items: Any selections already made will be marked as conflict=false. These should remain interactive in the UI. If a user clicks on a selection that is already chosen and marked as conflict=false, treat this as a deselection action, not a new selection. 
  {% endhint %}

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sportradar.com/uof/custombet-cb/api/calculate-filter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
