Search the Adobe Stock catalog by keyword with filters and control the response fields returned via result_columns

Steps

1. Register an application in the Adobe Developer Console to get an x-api-key value, and set a descriptive x-Product header value for every request
2. Call GET https://stock.adobe.io/Rest/Media/1/Search/Files with at least one search_parameters[] value, e.g. search_parameters[words]=dog+big+happy
3. Add filters like search_parameters[filters][orientation]=horizontal or search_parameters[filters][content_type:photo]=1 to narrow results (filters are ANDed except for content_type/template_type_id/template_category_id, which are ORed)
4. Control pagination with search_parameters[limit] (max 100) and search_parameters[offset], incrementing offset by limit to page through results
5. Add an Authorization Bearer header (obtained separately via Adobe IMS OAuth) if licensing/licensed-status information is needed in the response; omit it for anonymous browsing-only searches
6. Use result_columns[] to trim or expand the returned fields, e.g. result_columns[]=id&result_columns[]=title&result_columns[]=thumbnail_url
