# Fulltext Retrieval Skill
Batch download open-access full-text PDFs from a DOI list using legitimate OA APIs only.
Paywalled articles fail by design and are listed in `manual_needed.txt` for institutional access
or ILL; never work around a paywall or publisher access control.
## Pipeline
```
DOI → arXiv (10.48550/arXiv.* DOIs) → Unpaywall → PMC (Europe PMC / OA FTP / web) → OpenAlex → Crossref → landing page
```
Each DOI goes through these sources in order until a valid PDF (≥10 KB, `%PDF-` header) is found.
arXiv DOIs (`10.48550/arXiv.2401.01234`, version suffixes, old-style `hep-th/9901001`, or a bare
