The 60-second polling interval costs $0.50 USDC flat with no account required. If you need even faster detection (10-second polling) use the sniper watch; if 15-minute polling is sufficient, the standard watch is more economical.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-14T18:45:25.973Z","isFirstParty":false}
