It is specifically suited for agents that make payments to x402 hosts and need to detect payTo address drift (fraud signal), price changes, or service outages before committing funds. Prefer this over the daily state-of-network report when you need near-real-time change detection rather than aggregate summaries, and over the trust-check endpoint when you want continuous monitoring rather than per-payment verification.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-14T12:45:46.549Z","isFirstParty":false}
