Monitor a topic
Monitor a topic: call with a query (web or news) and a watchId; each call returns only the results you have not seen before (newResults) plus the full list, so polling agents stop re-reading old links and spending tokens on them. No setup: the first call creates the watch. Hashed URLs only, kept 60 days; the query text is never stored.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
