# Coverage limitations

OpenAlex: without an API key the service enforces a shared daily budget per IP (HTTP 401 after about 200 records on the search day); it was used only for verification.
Semantic Scholar: unauthenticated bulk endpoint, frequent HTTP 429; all queries completed with backoff; hit counts are the service's totals, retrieval capped at 20,000 per query (never reached).
Crossref: relevance-ranked bibliographic search returns hundreds of thousands of fuzzy matches; the first 4,000 per query were kept; most Crossref records carry no abstract, so their stage-1 screening is title-based.
arXiv: one query failed with HTTP 429 (logged); arXiv's all-field search is fuzzy and most hits are off-topic.
SSRN, Google Scholar, IDEAS/EconPapers, CORE, DOAJ, institutional repositories: no compliant bulk access from this environment; grey literature is covered only indirectly through Semantic Scholar and arXiv indexing.
Full texts: only legal open-access copies (Unpaywall locations, Semantic Scholar OA links, arXiv); paywalled studies that passed stage 1 are counted as 'not retrieved' in the PRISMA flow.
