Hi Ujwal,
Presently, there isn't a single API available to retrieve this count. To obtain it, you would need to iterate through the entities and utilize the "/entities/{{entityURI}}/_crosswalksTree" API, which provides the merge history of the entity. Within the response of the "/_crosswalksTree" API, you can find the mergeReason and mergeRules, which can be employed to calculate the count of automatic matches/merges.
Hope this helps.
