Getting started

The V‑Cloud API is a collection of REST web services that can be accessed by any programming language capable of performing HTTP POST and GET calls. The following sections detail some essential concepts to get started with V‑Cloud.

Querying V‑Cloud status

The V‑Cloud API is primarily used to submit audio files for transcription and to get results, but can also be used to determine if V‑Cloud is available by querying the /status endpoint.





A successful response returns HTTP code 200 and the text string OK if the V‑Cloud server is available. You do not need to pass a token to the service in order to make this call.

Authorization token

Tokens are used to authorize and authenticate requests made to the V‑Cloud API. Please protect your token as you would any other shared secret. Use of the token enables direct billing of transcription hours to your account.

Endpoints and methods

The V‑Cloud API is comprised of two core methods:


The /transcribe endpoint accepts POST requests containing an audio file or a zip file less than 250MiB containing one or more audio files to transcribe. Successful /transcribe requests return a requestid to identify results for retrieval and tracking.


The /transcribe/result endpoint accepts GET requests containing a valid requestid . Successful /transcribe/result requests return a URL with the results as a zip or JSON file. The format of your results depends on the options specified in the initial /transcribe request.


V-Cloud limits the /transcribe endpoint to 128 concurrent connections per IP address and the /transcribe/result endpoint to 32 concurrent connections per IP address.
