Steps
GET /rr_model?key=<key>&flags=<flags> to query the object model (e.g. key=boards[0]), using flags like f (frequently-changing values only) or v (verbose) as needed.
GET /rr_filelist?dir=<path> (or /rr_files for a plain name list) to enumerate files, paging via the returned first/next fields for large directories.
POST /rr_upload?name=<path>&crc32=<hex> with the raw file body to upload a G-code file, then GET /rr_upload to confirm the last upload result.
GET /rr_fileinfo?name=<path> to parse a G-code file's metadata (print time, filament use, embedded thumbnails) before printing it.
Known gotchas
The crc32 parameter on rr_upload is optional but recommended — omitting it skips integrity verification of the uploaded content.
Thumbnail extraction is a separate follow-up call to /rr_thumbnail using the offset values returned by rr_fileinfo, not part of the fileinfo response itself.
