Using API of Adobe stock

Hi.

There is no public API to show all the assets from a single contributor. Why are you trying to get this data? Are you the contributor named Designstockio?

You can search within a contributor's art, but not display their whole collection. The search parameter 'creator_id' is used for this. Here is a sample curl that uses the search API to find all the assets with the keyword "star" by this Contributor. You will need to get your own API key.

curl 'https://stock.adobe.io/Rest/Media/1/Search/Files?search_parameters%5Bcreator_id%5D=211240734&search_parameters%5Bwords%5D=star' --header 'X-Product: CFSTest/1.0' --header 'x-api-key: MY_API_KEY'
