    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Scope a multi-term question with a boolean filter: +must -exclude "exact topic" (a OR b) wild* year:2015..2026, over element symbols or names and EXACT topic names (e.g. +Li +Co "solid electrolyte" -sulfide). Words that are neither are DROPPED, and wildcards can expand into unrelated fields: read `warnings` first -- it lists every dropped term with the nearest topics, every abbreviation read as a topic, and every wildcard expansion. Returns how many papers match, by year and by research community, the nearest broader query when nothing matches, and a quote_id that lab_run turns into the ranked papers. Narrow filters (two elements + one topic) work best. Requires a Professional+ account. Without a key, pay per call: $0.01 in USDC on Base or Solana via x402 (send the payment in _meta["x402/payment"]).

    • The name "lab_run" says "run": a word for a change.
    Description, as the server wrote it
    Get the papers for a lab_quote: pass its quote_id and a depth (papers_20 or papers_100) to get the top papers matching the quoted filter, ranked by impact, with the curation behind each rank. Each paper carries its abstract where one is on file (about 6 in 10). A stale or expired quote is refused. Requires a Professional+ account. Without a key, pay per call: the quoted price of the depth, less the $0.01 quote credit in USDC on Base or Solana via x402 (send the payment in _meta["x402/payment"]).

    • The description's first verb is "call": a word for a change.
    Description, as the server wrote it
    CALL THIS FIRST for a literature question about chemistry, materials or physics research -- a broad one ('what matters in X') or a specific process or parameter one (a deposition condition, a property value, a defect mechanism). Send the question in plain words (q), or a paper you already know (paper: DOI or title). Returns reading lists in four lenses: relevant (the papers whose TITLE AND ABSTRACT best match the question, across the whole corpus, BM25 -- start here for a specific question), foundational (the classics the question's own papers cite most), now (highest impact, young papers' citations projected) and newest (last two years); plus the research communities and element sub-communities the question is about, with why each matched and whether it is rising. Put the question's key terms in q: filler words are ignored. unmatched_terms lists words that matched nothing; rephrase those. Each paper carries its DOI, a one-line reason and its abstract where one is on file. Our corpus is curated, not complete: the relevant lens also brings up to 3 of every 10 results from OpenAlex, marked source='openalex' and labelled not yet curated. One page = up to 10 papers per lens; ask for page 2+ only if needed. Requires a Personal+ account. Without a key, pay per call: $0.05 in USDC on Base or Solana via x402 (send the payment in _meta["x402/payment"]).

    Why it is in this group

    • The name "get_element_papers" says "get": a word for reading.
    Description, as the server wrote it
    The top papers for one element, narrowed with keyword to one of its materials or applications (e.g. symbol='Al', keyword='aluminum nitride'; the keyword must name one of the element's topics exactly, case aside -- search_subjects finds topic names). Returns title, DOI, venue, year, citations. sort=impact (default) favours recent, well-cited work; sort=foundational gives the most-cited classics; sort=newest the latest. Each paper carries its abstract where one is on file (about 6 in 10). Requires a Personal+ account. Capped at 100 papers with no pagination. Without a key, pay per call: $0.02 for up to 20 papers, $0.10 for up to 100, in USDC on Base or Solana via x402 (send the payment in _meta["x402/payment"]).

    • The name "get_element_ri" says "get": a word for reading.
    Description, as the server wrote it
    Get current Research Intensity (RIS) for one of the 118 chemical elements, with a citation URL. No API key needed. Historical RI (HRI) is included with a Personal+ key.

    • The name "get_subject_history" says "get": a word for reading.
    Description, as the server wrote it
    Full yearly (or monthly) RIS/HRI history for one topic/keyword/sector. Requires a Personal+ account. Without a key, pay per call: $0.10 in USDC on Base or Solana via x402 (send the payment in _meta["x402/payment"]).

    Why it is in this group

    • The name "get_subject_papers" says "get": a word for reading.
    Description, as the server wrote it
    The top papers for one research topic (resolve it with search_subjects first) -- title, DOI, venue, year, citations. Use it when asked what to READ about a specific topic, rather than how active it is. sort=impact (default) favours recent, well-cited work; sort=foundational gives the most-cited classics; sort=newest the latest. Each paper carries its abstract where one is on file (about 6 in 10). Requires a Personal+ account. Capped at 100 papers with no pagination. Without a key, pay per call: $0.02 for up to 20 papers, $0.10 for up to 100, in USDC on Base or Solana via x402 (send the payment in _meta["x402/payment"]).

    Get RI, RIS, HRI and paper count for one research topic/keyword/sector. Requires a Personal+ account -- call search_subjects first to resolve subject_type/subject_id. Without a key, pay per call: $0.01 in USDC on Base or Solana via x402 (send the payment in _meta["x402/payment"]).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
