  • naulon_discover

    Browse a TOPIC: list candidate articles, each with its slug, title, free teaser, url and an indicative price where the source lists one, and no verdict on whether it answers a question. It returns no paid text and pays nothing. Call it first, then naulon_appraise to score the ca…

  • naulon_appraise

    Score how relevant each candidate is to the topic from its free teaser alone: a relevance from 0 to 1 and a one-line rationale for each. Call it on the rows naulon_discover returned, to decide which are worth a live price from naulon_quote. Calls are limited per caller: a refuse…

  • naulon_quote

    Read the live toll for ONE source without paying it: the author's price, the buyer's total (higher when the publisher adds settlement legs such as an operator fee) and the settlement terms. Call it on a candidate from naulon_discover, whose listed price is only indicative: this…

  • naulon_search

    Ask a QUESTION: search every naulon publisher's articles and get each match with its price, public summary, `url`, and a verdict on whether it answers the question and what reading it would add. For a plain list of a topic's articles with no verdict, call naulon_discover. For on…

  • naulon_check_citations

    Check citations before you cite them: for each reference, say whether the work exists and whether it was retracted, withdrawn, corrected or put under an expression of concern. Facts from Crossref and Retraction Watch, with no judgement of the research. For the full record of one…

  • naulon_trace_passage

    Find which naulon publisher pages a passage was copied from, word for word. Returns each page's title and url, whether it holds most of the passage or part of it, and how many Citation Licenses the page has sold where its publisher shows that. Use it on text you were given, to l…

  • naulon_lookup

    Get the record of ONE source you already have the address of: a publisher page by its URL, or a paper by its identifier. A page returns its title, site, summary and read and citation prices. A paper returns its title, authors, venue, year, retraction and correction notices, lice…

  • naulon_retrieve

    Preview RESEARCH PAPERS for a question: list the open CC0, CC BY, CC BY-SA or public-domain papers an answer could quote, and the price of each way to run it. `answer` is an answer written only from quotes proven against the papers; `retrieve` is the proven quotes alone. It is f…
