Papers

Academic and scientific paper search API.

Overview

Academic and scientific paper search API. Search research papers and scholarly literature across arXiv, PubMed, OpenAlex, Crossref, and Semantic Scholar in one call, deduplicated into a ranked result set — title, authors, year, venue, abstract, citation count, DOI, and direct PDF link. Query by keyword or restrict to a single source (arxiv search, pubmed search, crossref, openalex, semantic scholar); filter by year range; sort by relevance, recency, or citations. Keyless.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i https://api.jarvisclaw.ai/v1/marketplace/api/papers-4184

# 2. Pay it (the SDK signs and retries for you)
curl -H "X-PAYMENT: <signed-payload>" https://api.jarvisclaw.ai/v1/marketplace/api/papers-4184
