back.nber.org/rss/new.xml. Each paper carries the NBER identifier (w{N}), title, author list, canonical link, optional publication timestamp, and the full abstract. The upstream feed contains roughly 30 items spanning the most recent 5-7 business days; NBER does not publish <pubDate> on feed items, so the pub_date field is usually null and callers should order by paper_id when recency matters.x-api-key: ********************curl --location '/api/v1/research/nber/papers/latest?limit=20' \
