The Solr API is used to manage collection-level configurations. The path for this request is: 
https://EXAMPLE_COMPANY.b.lucidworks.cloud/api/solr/COLLECTION_NAME/SOLR_REQUEST
Replace COLLECTION_NAME with the name of a specific collection and SOLR_REQUEST with the Solr command you wish to run. Since this API proxies requests to Solr, each available method corresponds to the method in Solr. So, a GET request to Solr would use the GET method of this endpoint; a POST would use the POST method, etc. Depending on the request, the response may consist of records that match a query or output from a Schema API request. For more information, view the API specification.
