Empty fire_detections with fetched_at=0 or data_available=false means the seed snapshot is unavailable/degraded, not that there are confirmed zero fires. ## OpenAPI ````yaml /api/WildfireService.openapi.yaml get /api/wildfire/v1/list-fire-detections openapi: 3.1.0 info: title: WildfireService API version: 1.0.0 servers: - url: https://api.worldmonitor.app security: - WorldMonitorKey: [] - ApiKeyHeader: [] paths: /api/wildfire/v1/list-fire-detections: get: tags: - WildfireService summary: ListFireDetections description: >- ListFireDetections retrieves satellite-detected active fires from NASA FIRMS.
