This skill should be used when the user asks to "search for academic papers", "find working papers on SSRN", "look up a DOI", "download paper PDF", "check open access availability", "search NBER papers", "find arXiv preprints", or "search CrossRef". Provides unified search, metadata retrieval, and PDF download across arXiv, NBER, SSRN, CrossRef, OpenAlex, Unpaywall, and Semantic Scholar. Covers economics, finance, social science, CS/AI, and all academic disciplines.

I want to query the NBER working paper API and restrict results strictly to papers published in 2024 using URL query parameters. What parameter name does the NBER endpoint accept for publication year filtering?
| Checked | Without skill | With skill |
|---|---|---|
| States that the NBER API does not support search filtering by publication year | Missed | Passed |
| Recommends filtering results client-side using the displaydate field | Missed | Passed |

A unified toolkit for discovering, retrieving metadata, and downloading academic papers across all major sources. The right API depends on the task — this skill routes to the best source.
What is needed?
│
├─ SEARCH for papers on a topic
│ ├─ arXiv preprints (CS/AI/Physics/Econ) ──→ arXiv API
│ ├─ NBER working papers (economics) ───────→ NBER API
│ ├─ SSRN working papers (social science) ──→ OpenAlex (primary) + CrossRef prefix:10.2139
│ ├─ Published journal articles ────────────→ CrossRef API or OpenAlex
│ └─ Broad multi-source search ─────────────→ OpenAlex API
│
├─ GET METADATA for a known paper
│ ├─ Have DOI ──→ CrossRef (structured) or OpenAlex (richer)
│ ├─ Have arXiv ID ──→ arXiv API
│ ├─ Have NBER number ──→ NBER API
│ └─ Have SSRN abstract ID ──→ OpenAlex DOI lookup (DOI = 10.2139/ssrn.{id})
│
├─ FIND/DOWNLOAD PDF
│ ├─ Have DOI ──→ Unpaywall API (check OA) → OpenAlex (alt PDF links)
│ ├─ arXiv paper ──→ Direct: https://arxiv.org/pdf/{id}
│ ├─ NBER paper ──→ Direct: https://www.nber.org/system/files/working_papers/w{n}/w{n}.pdf
│ └─ SSRN paper ──→ Unpaywall (~30%) or institutional repos (EconStor, IZA)
│
└─ IMPORT TO ZOTERO
└─ Always use zotero_add_by_doi (best metadata + auto PDF via Unpaywall cascade)
