Subject: [PATCH] Ensures transaction offset is a valid number

Addresses an issue where the transaction offset could be non-numeric, causing errors in pagination.

Adds validation and parsing to ensure the offset is always an integer, falling back to 0 if necessary.  Also ensures that limit is parsed into an Int.
