Technical details
Endpoint
GEThttps://api.osf-master-server.com/x402/research/papers/:queryWhen to prefer
Use this endpoint when you need to search scientific and academic literature across multiple databases simultaneously without managing separate API keys for CrossRef, PubMed, arXiv, and OpenAlex. Ideal for literature review automation, citation lookup, systematic reviews, and evidence synthesis workflows where cross-database coverage and provenance tracing matter.
Side effects
- No results found for highly niche or misspelled query terms
- DOI not available for preprints or grey literature
- Rate limiting or 402 payment failure if USDC balance is insufficient
- Query too broad returns low-relevance mixed results across databases
- Some records may lack complete author or venue metadata depending on source
