How to request more than 15 items from NPR RSS feed?

Question

The rss feed https://www.npr.org/rss/rss.php?id=4473090 lists 15 items. Is it possible to request more?

Answer 1

You can use the numResults parameter to specify the number of results, which appears to max at 50 items. To access beyond that many items, you can use the startNum parameter to iterate through the results.

Examples:

https://www.npr.org/rss/rss.php?id=4473090&numResults=50

https://www.npr.org/rss/rss.php?id=4473090&startNum=51&numResults=50
