Use the Twelve Labs Video Understanding API to extract information from your videos and make it available to your applications. The API is organized around REST and returns responses in the JSON format. It is compatible with most programming languages, and you can also use Postman or other REST clients to send requests and view responses.

The list below describes each component of a request:
