Parallel Monitor tracks web changes and sends structured event notifications.
Parallel Monitor runs natural-language web queries on hourly, daily, or weekly schedules. It filters previously surfaced results and delivers new events through webhooks with summaries, timestamps, and source URLs.
Teams can use the API for competitive intelligence, regulatory monitoring, and market signals. Scheduled delivery connects newly discovered information to application workflows without requiring users to repeat each search manually.
