search_papersSearch the NobleBlocks index of scholarly papers by keyword relevance, with filters. Each result has title, authors, year, journal, DOI, citation count, an abstract excerpt, a NobleBlocks link and `best_link` (free full text when known, else the DOI/ARK). Use get_paper with a re…
search_trialsSearch clinical trial registrations (ClinicalTrials.gov or WHO ICTRP) held in the NobleBlocks index. Each result carries its registry id (`trial_id`, e.g. NCT01234567). Use get_paper with that id for the full record.
get_paperFull metadata for one paper or trial: authors, journal, volume/issue/pages, identifiers (DOI, PMID, arXiv, OpenAlex, trial id, NobleID ARK when confirmed), retraction status, open access link, citation count, abstract and links (`links.best` is open access first).
get_citing_papersPapers in the NobleBlocks index that cite this paper, most cited first. Citation links are still being loaded, so an empty answer is reported as such, not as 'never cited'.
get_referencesPapers this paper cites (its reference list) that are in the NobleBlocks index, most cited first.
search_authorsFind researchers by name. Returns name, ORCID iD, OpenAlex id, affiliation and reported counts. Use get_author with an ORCID iD for the profile and top papers.
get_authorOne researcher's public profile by ORCID iD: name, affiliation, topics, reported metrics, NobleID when recorded, and their most cited papers in the index.
get_citationFormat a citation for one paper as BibTeX, RIS or APA 7. The URL is the paper's NobleID ARK when it has a confirmed one, else its DOI. DOIs known to be unreliable are left out rather than guessed.
citeCitations for several papers at once, in one format, in the order given. Each entry links to the ARK or DOI; failures are listed per identifier instead of failing the whole call.
searchSearch scholarly papers and return citable results as {results: [{id, title, url}]}. `url` is open access first. Pass an `id` to fetch for the full text record.
fetchFetch one paper as {id, title, text, url, metadata}. `text` is the abstract plus a formatted citation; `url` is open access first.
