It is the most cost-effective watch option for long-duration monitoring where near-real-time response is not critical. Prefer the sniper watch (10-second polling) for urgent or fast-changing targets, or the fast watch (60-second polling) for medium-frequency needs. Use this for price tracking, content-change detection, and keyword or JSON path watches on pages that update infrequently.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-14T18:43:18.110Z","isFirstParty":false}
