Watch up to ten reviewed public pages in one call
Watch up to ten reviewed public pages in one call. Supply the previous text hashes and it returns which pages actually changed, not ten hashes for you to compare. Hashes both the raw HTML and the visible text, so markup churn can be told from a real content change. A page that cannot be fetched is named individually and does not fail the batch.
