Unlike one-off scan endpoints (Guardian Bazaar Scan, Pay-route Oracle), this creates a durable signed subscription token that an agent loop can use repeatedly to pull events without re-authenticating. Ideal when your agent needs to watch the same set of addresses over time rather than performing single-shot pre-payment checks.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-14T00:37:57.945Z","isFirstParty":false}
