Technical details
Endpoint
POSThttps://clonecho.builda.company/x402/research-papersWhen to prefer
Use this endpoint when you need to search peer-reviewed academic or scientific literature at scale (150M+ works) and need structured metadata including DOIs and citation counts. Prefer it over general web search when the user explicitly wants scholarly sources, academic citations, or research papers indexed through CrossRef.
Side effects
- Empty query string returns no results or an error
- Very broad queries may return too many loosely relevant results
- Highly specialized or very new papers may not yet be indexed in CrossRef
- Query with special characters may need URL encoding
- Rate limiting or payment failure may result in a 402 response
