I may be blind but I can't see any api call to delete a custom value?!
CustomValue entity is missing a delete action.

If you have the ID of the row you want to delete and the custom group ID you can use
$dao = CRM_Core_BAO_CustomGroup::class; $groupID = CRM_Core_DAO::getFieldValue($dao, 'Emergency_Contacts', 'id', 'name'); CRM_Core_BAO_CustomValue::deleteCustomValue($id, $groupID);
Which deletes an entire row from the custom value table for this custom group.
Currently, you can't do this. If you try, you will get the notice:
API (CustomValue, delete) does not exist (join the API team and implement it!)
This is true for CiviCRM version 4.7.7, which is current at time of writing.
