Tool of Academic Research Intelligence MCP

declared in 3.4.2

Find related academic papers by semantic similarity — the "related work" finder for a literature review. Give a free-text query OR a paper_id and get the most similar papers via fastembed semantic similarity (pgvector). Premium. PAID: $0.02 USDC per query after the daily free allowance (25/day). On a 402, pay the returned Solana memo and re-call with the SAME args plus payment_tx=<signature>. An Authorization: Bearer fnet_ key bypasses it.
