Only 2 weeks data?

We are making a call to the Analytics API / Published Posts. 

curl -s --request POST --url 'https://api.spredfast.com/v2/analytics/export/posts?header=true&delimiter=%2C' -H 'accept: application/json'  -H 'content-type: application/json' -H 'Authorization: Bearer $khorosAPIKey' --data '{"query": {"start":"2023-01-01","fields":[$Include_Fields]}}'

No matter what I do I only get data going back 2 weeks.  This is with or without a start/stop date

Any idea why?  We have been using Khoros since 2023
