search_papers
ActiveTool of Academic Research Intelligence MCP
declared in 3.4.2
Search academic papers across OpenAlex, arXiv, and PubMed for literature reviews — filter by query, year, field, venue, citation count, or open access. Returns title, authors, abstract, and citation count (sorted by citations). PAID: $0.01 USDC per query after a daily free allowance (25/day). On a 402, pay the returned Solana memo and re-call with the SAME args plus payment_tx=<signature>. agent_id scopes your allowance; an Authorization: Bearer fnet_ key bypasses it.
