The public API enforces limits per workspace and API key to protect shared processing capacity.

​
Defaults

These are the current service defaults. They can be adjusted by environment configuration.

​
Allowed upload content types

Direct uploads currently accept: Video (transcript, vision, retake-removal):
  • video/mp4
  • video/quicktime
  • video/webm
Audio (transcript only):
  • audio/mpeg
  • audio/mp4, audio/x-m4a
  • audio/aac
  • audio/wav, audio/x-wav
  • audio/flac, audio/x-flac
  • audio/ogg
  • audio/webm
Audio projects are transcript-only: vision and retake-removal return 422 Unprocessable Entity. Their upload-complete response reports width and height as null. Uploads outside the allowed content types or above the configured maximum are rejected before analysis starts.

​
Usage tracking

Request and action usage is tracked for API keys and workspaces, including:
  • total requests
  • successful and failed requests
  • projects created
  • uploads started and completed
  • uploaded bytes
  • transcript commands
  • vision commands
  • retake-removal commands
This usage is used for rate limits, debugging, and billing or quota views.

​
Credit billing

When workspace credit billing is enabled, starting transcript, vision, or retake-removal analysis charges the workspace wallet based on source duration. Speaker diarization is an opt-in add-on to transcript and is billed separately. If the workspace has no billing wallet or does not have enough credits, the API returns 402 Payment Required and does not start the analysis.
