List Files

​
method
GET
GET /api/cameras/{cameraId}/sd-card/slot/{slotNumber}/files
​
slotNumber

required
SD card slot: 1 or 2
curl http://localhost:8080/api/cameras/D10F60149B0C/sd-card/slot/1/files

​
Download File

​
method
POST
POST /api/cameras/{cameraId}/sd-card/slot/{slotNumber}/files/{contentId}/{fileId}/download
Download a specific file from the SD card to the host PC.
​
contentId
integer
required
Content ID from file listing
​
fileId
integer
required
File ID from file listing
​
save_path
string
Directory on host PC to save the file
curl -X POST http://localhost:8080/api/cameras/D10F60149B0C/sd-card/slot/1/files/12345/67890/download \
  -H "Content-Type: application/json" \
  -d '{"save_path": "/Users/me/Photos"}'
Listen for transferProgress SSE events to track download progress in remote-transfer mode.

​
Download Thumbnail

​
method
POST
POST /api/cameras/{cameraId}/sd-card/slot/{slotNumber}/files/{contentId}/{fileId}/thumbnail
Download a compressed JPEG thumbnail (~50-60 KB) for fast preview or ML evaluation. Much faster than pulling the full file.
​
contentId
integer
required
Content ID from file listing
​
fileId
integer
required
File ID from file listing
​
save_path
string
Directory on host PC to save the thumbnail
curl -X POST http://localhost:8080/api/cameras/D10F60149B0C/sd-card/slot/1/files/12345/67890/thumbnail \
  -H "Content-Type: application/json" \
  -d '{"save_path": "/Users/me/thumbnails"}'

​
Download Screennail

​
method
POST
POST /api/cameras/{cameraId}/sd-card/slot/{slotNumber}/files/{contentId}/{fileId}/screennail
Download a medium-resolution JPEG preview (~250-300 KB). Higher quality than thumbnail, still much smaller than the full file.
​
contentId
integer
required
Content ID from file listing
​
fileId
integer
required
File ID from file listing
​
save_path
string

  -H "Content-Type: application/json" \
  -d '{"save_path": "/Users/me/previews"}'
Size comparison for ML workflows:
TypeSizeUse Case
Thumbnail~50-60 KBFast ML triage, grid views
Screennail~250-300 KBDetailed evaluation, composition analysis
Full file~35 MB (ARW)Final delivery, full processing
Both thumbnail and screennail endpoints are async — listen for transferProgress SSE events with percent: 100 for completion.
