Get asset content

Returns the binary content of an asset by ID.

The contract is the same across runtimes — "GET this path and you receive the asset's bytes" — but the mechanism differs:

  • Local ComfyUI streams the bytes directly (200, application/octet-stream).
  • Cloud does not proxy large files; it responds 302 with a Location redirect to a short-lived signed storage URL. Clients that follow redirects (browsers, fetch/XHR, <img>/<video>) receive the bytes transparently.

Prefer this over the filename-addressed /api/view when you have an asset ID.
