Tools & capabilities
Anna's Archive tools 7
account_statusShow the account's membership and how many fast downloads it has left in its rolling window. Check it before downloading many files.article_downloadDownload a selected paper by exactly one of doi or hash. The hash field accepts a bare MD5 or an Anna's Archive /md5/ page URL. Resolves a DOI to its hash, then returns an existing file in ANNAS_DOWNLOAD_PATH if its full MD5 matches, otherwise downloads under a unique name. Returns path and bytes; downloads_left is omitted on local reuse. Optional title and format control a new file's name.article_searchFind a paper by DOI (including DOI URLs), or search journal articles by keywords, author, title or year. DOI lookup returns one paper; keyword search returns one page. Set include_stats to add public per-file downloads, quality votes, reports, lists and comments. Compare metadata before downloading by hash or DOI.book_detailsGet the full record for a search hit: ISBNs, DOI, OCLC and other identifiers, edition, year, full description, subjects, alternative titles, problems reported for the file, and download and quality counts. Accepts a hash from book_search or article_search, or an id from metadata_search.book_downloadDownload the selected book using its MD5 hash or Anna's Archive /md5/ page URL in hash. Returns an existing file in ANNAS_DOWNLOAD_PATH if its full MD5 matches, otherwise downloads a verified copy under a unique name. Returns path and bytes; downloads_left is omitted on local reuse. Format sets the extension; it does not convert the file.book_searchSearch books, textbooks, manuals and standards by title, author or topic, optionally filtered by format, language, content type, source library or year and sorted. Returns one page with hash, format, year, fast_download and metadata. Set include_stats to add public per-file downloads, quality votes, reports, lists and comments. Pass a selected hash to book_download, or to book_details for ISBNs, edition and file problems.metadata_searchSearch library catalogs (Open Library, WorldCat, ISBNdb, Goodreads, Google Books and others) for books, including ones with no downloadable file. Use it to find ISBNs, editions and publication details, then search book_search by ISBN or title for files. Pass an id to book_details for identifiers.
HasData Google Scholar tools 3
hasdata_google_scholar_case_law_getScholarCaseLawOpinionGet Scholar Case Law Opinion Looks up a Google Scholar Case Law opinion by its `caseId` (as returned in a google/scholar organic result's `caseId`, when searching with `asSdt` set to a case-law court scope, or in another case-law result's `citedCases`). Returns the case title, party names, court, procedural history, argued/decided dates, short citations, docket numbers, and every case cited within the opinion (grouped by cited case with a ready-to-call `hasdataLink`). Use to build legal-research and case-law-analysis workflows, or to walk a citation graph one cited case at a time.hasdata_google_scholar_cite_getScholarCitationFormatsGet Scholar Citation Formats Looks up citation formats and export links for a single Google Scholar organic search result, identified by its `resultId` (as returned in a google/scholar organic result). Returns formatted citation snippets (MLA, APA, Chicago, Harvard, Vancouver) and reference-manager export links (BibTeX, EndNote, RefMan, RefWorks). Use to build citation/bibliography features or complete a research workflow started with google/scholar.hasdata_google_scholar_scholar_getScholarSearchResultsGet Scholar Search Results Scrapes Google Scholar for a query with author:/source: search helpers, year range (asYlo/asYhi), cited-by and all-versions lookups (cites/cluster), review-article and citation-inclusion filters, language/language-restrict, start/num pagination, and asSdt to scope to case law (asSdt=2006 for all courts, 2003 for Federal courts only, or 4/6/3 plus comma-separated court codes for specific courts) or toggle patents. Returns each organic result with title, link, snippet, publication info (authors with profile links), cited-by count and link, related-articles link, and all-versions count and link; a case-law result links to a scholar_case?case= page and carries a ready-to-call caseHasdataLink. Use for academic research, literature review automation, citation tracking, grounding research agents with scholarly sources, and walking case law straight into google/scholar-case-law.
