FAQPage Schema

How do I poll RSS feeds and GitHub for new items without duplicates?▼

Poll RSS, JSON, and GitHub activity via watchers to surface new items without duplicates. A watermark-based dedup system tracks state locally, ensuring only new entries are emitted on subsequent runs.

Can I run a JSON endpoint watcher on a cron schedule?▼

JSON endpoint watchers run on cron or ad hoc. You configure a watcher name and target endpoint, and the system handles polling, deduplication, and state storage for cross-session recall.

How does watermark deduplication work for monitoring API streams?▼

Watermark deduplication tracks the last processed item from API streams to filter out previously seen entries. It establishes a first-run baseline and stores state locally to recall progress across sessions.

Do I need extra dependencies to monitor GitHub repository events?▼

Monitoring GitHub repository events requires no special setup or extra dependencies. You simply provide a watcher name and the target GitHub endpoint to start polling and delivering new activity.

What is the best way to format GitHub activity polling results for chat channels?▼

Format GitHub activity polling results for chat channels using Markdown rendering. The watchers output Markdown natively, making it easy to deliver alerts or summaries directly to terminal workflows or emails.

How are network or API issues handled when polling external data sources?▼

Network or API issues are handled by built-in error handling within the watchers. This prevents polling failures from breaking the workflow when monitoring RSS feeds, JSON endpoints, or GitHub activity.
