Since the introduction of the JSON API you can provide media files at the input for both insert and query operations. The origin of these media files may vary, though quite often they do come from popular media platforms like YouTube or Twitter.

In order to simplify the workflow you can now fingerprint Audio (or Video) streams by providing links at the input. Below is a short example on how to fingerpring Audio stream from Bach Air on G String.

 curl --request PUT \
  --url 'http://localhost:3340/api/v1.1/tracks?' \
  --header 'Accept: application/json' \
  --header 'Authorization: Basic Admin:' \
  --header 'Content-Type: application/*+json' \
  --data '{"id":"e96d43b7-0f02-486c-a6d5-acc6bbfdd7be","title":"Bach Air on G string Piano","artist":"Valentina Lisitsa","mediaType":"Audio"}'

Once inserted you can query it with a similar HTTP request:

 curl --request GET \
  --url 'http://localhost:3340/api/v1.1/tracks?' \
  --header 'Accept: application/json' \
  --header 'Authorization: Basic Admin:' \
  --header 'Content-Type: application/*+json'

Provided response will contain match related infomration.
