如何使用 REST api 查询 IBM Watson Discovery News？

Question

Is there an opportunity in IBM Watson Discovery News to query news just with the url where I can specify keywords, api etc. Would appreciate if anybody could share the template of such REST request. I created the account, launched the Discovery but then completely lost in the IBM Cloud API Docs https://cloud.ibm.com/apidocs/discovery . As far as I can see, here everything is for accessing via command line but it is not what I'm looking for...

This is what I used for Alchemy:

https://access.alchemyapi.com/calls/data/GetNews?apikey= &return=enriched.url.title&start=1477008000&end=now&q.enriched.url.cleanedTitle=InsertTitle&count=100&outputMode=xml

Best, Lada

Occasionally all you need to do is read the documentation - https://cloud.ibm.com/apidocs/discovery#query-a-collection-get

curl -u "apikey":"{apikey}" "https://gateway.watsonplatform.net/discovery/api/v1/environments/system/collections/news-en/query?version=2019-04-30&natural_language_query=corvid&count=10&return=text"

which becomes

https://apikey:{apikey}@gateway.watsonplatform.net/discovery/api/v1/environments/system/collections/news-en/query?version=2019-04-30&natural_language_query=corvid&count=100&return=text

although if you just run

https://gateway.watsonplatform.net/discovery/api/v1/environments/system/collections/news-en/query?version=2019-04-30&natural_language_query=corvid&count=10&return=text

you will be prompted for credentials.

You may need to amend the url endpoint to reflect the region you have your discovery service instance.
