Signed webhook application
Receive a durable signal when a new disruption Event is coded near a Red Sea operating area, then hydrate application state with complete API results.
The webhook contains at most ten representative matches; the run replay request retrieves the complete result with QU. Verify the signature over timestamp plus raw bytes before parsing, enforce the five-minute replay window, and deduplicate event IDs. localhost HTTP is allowed only behind the local development flag; production destinations must be public HTTPS. Use custom QU-backed polling only when the deliberately constrained Monitor builder cannot express the recurring logic. volume_spike is deferred; the trigger is new_matches. A Monitor reads one lane: this one reads Events, because an application dedupes and reconciles discrete incidents. Point a second Monitor at Stories if the app also needs coverage.

}After the notification
Scheduled checks cost 0 QU. Investigation and application calls use QU.
Persist X-GDELT-Event-Id with the application side effect so retries are idempotent.
Execute the run replay_requests for the complete Event result window.
Use custom recurring QU polling only for unsupported multi-endpoint logic, custom state, or custom schedules.
