+
+- europepmc.org/articles/PMC5924899?pdf=render
+- europepmc.org/api/getPdf?pmcid=PMC5924899
+- wget same URL
+- curl -L same URL
+
+## Notable failures
+
+- pnas.org direct (HTTP 403 Cloudflare/bot block)
+- doi.org redirect to pnas (403)
+- paperscraper save_pdf (all built-in fallbacks failed: XML 404, PNAS PDF 403)
+- Unpaywall (422 with example.com email / no url_for_pdf)
+- BioC-PMC XML missing
+- PMC OA package (idIsNotOpenAccess)
+- NCBI PMC /pdf/ HTML interstitial
+
+## Library fix (follow-up)
+
+`fallback_europepmc` previously only fetched `fullTextXML` (404 for this DOI).
+It now falls back to `https://europepmc.org/articles/{pmcid}?pdf=render`.
+
+After the fix, `save_pdf({"doi": "10.1073/pnas.1718406115"}, ...)` returns:
+`{'success': True, 'method': 'europepmc', 'filetype': 'pdf'}`.
