MYOB Exo API and Integration

Does anyone have any issues with MYOB Exo API returning partial and erratic data?

We utilize the EXO API for our ecommerce website.

Our online store syncs product data and prices through the API connection. Currently, we retrieve product prices via the "SalePrices" object array using the following endpoint:https://exo.api.myob.com/stockitem/{sku} 

Recently, we've encountered an issue where SalePrices for certain products show as 0 through API calls, while in EXO, the prices display correctly.

We have over 3000 SKUs published on our website, and many of these products are experiencing this issue.

It's important to note that this behavior is erratic, meaning the API call sometimes provides correct pricing.

Any ideas on a solution which is consistent and sustainable? Or for that matter the cause of the issue in the 1st place?
