Single Answer Only

Single Answer Only

The single_answer_only parameter is not required and allows you to filter questions so that only those with exactly one correct answer are returned.

This is especially useful when you want to create simpler quizzes where users don't need to select multiple options.

{info} This parameter is only available for the /api/v1/questions endpoint and not for the /api/v1/ai endpoint.

Example

The request would look something like this:

curl https://quizapi.io/api/v1/questions -G \
-d apiKey=YOUR_API_KEY \
-d single_answer_only=true

When you set single_answer_only=true, you'll receive only questions where multiple_correct_answers is false. This means all returned questions will have exactly one correct answer among the available options.
