OpenFDA API: How to Page Past the 25,000 Record Limit
The openFDA adverse event API caps skip at 25,000, but a search_after cursor in the Link header allows unlimited paging. Testing showed 31,968 unique records across 32 pages in 70.9 seconds. A non-zero skip parameter silently degrades the cursor, causing loops to hit the wall.
