Constraints & best practices

Formats. Images: JPEG, PNG, WEBP. Video: MP4 and common containers. Audio: MP3, WAV, FLAC, M4A, AAC, OGG.

Size caps. Image ≤ 10 MB, video ≤ 25 MB, audio ≤ 25 MB — the same ceilings the dashboard enforces, so a file that uploads there uploads here. A file over its cap returns 413.

Verdicts are decisive, but confidence is probabilistic — tune thresholds per flow rather than hard-coding one cutoff, and keep the id from every response for tracing and support.
