Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • fetch

    Download a resource's files to local disk and return the PATHS (never the file contents). Fetchable backends: Zenodo (md5-verified); SRA via ENA FASTQ (md5-verified); GEO supplementary files (unverified); DataCite sub-repos — Figshare/Dataverse/OSF (md5-verified), OpenNeuro (snapshot manifest, unverified), Dryad is manifest-only (resolve lists files, fetch fails loud), Mendeley + other DataCite repos fail loud; PubMed/OpenAIRE open-access full text (EuropePMC XML / Unpaywall PDF, unverified); HuggingFace Hub (unverified); DataONE Member-Node objects (md5/SHA-256-verified); OmicsDI — PRIDE (unv…

  • list_sources

    List wired data sources and their capabilities (layer, kinds, supported filters, auth requirement, rate limit, status). filters_supported names the search parameters a source applies itself: cursor = it pages past page 1; published_after/published_before/kind = filtered upstream, so its total is filtered (any other source is filtered after fetch); organism/disease/tissue/chemical/assay = the synonym expansion reaches its query.

  • operate

    Inspect or query a remote tabular file (Parquet/CSV/TSV) WITHOUT downloading it. op='schema' returns columns+types; 'preview' a small sample; 'head' the first n rows; 'sql' a read-only SELECT against the file (exposed as the view 'data', e.g. "SELECT * FROM data WHERE x > 1"). op='peek' profiles every column WITHOUT downloading — type, null-rate, approximate distinct count, min/max, and numeric quartiles (a DuckDB SUMMARIZE; like head/sql it reads the whole file, so it honors the source-size ceiling). Addresses a file by catalog id + file name (resolve the id first to see files[] and access_mo…

  • relate

    Given 2-10 resource ids, return metadata-level join/harmonization HINTS: how the datasets relate and on what key they could be joined. Detects shared accessions (BioProject/SRA/GEO), shared cross-identifiers (doi/pmid/pmcid), explicit links between the inputs, and version lineage. HINTS ONLY — it does not read file columns, fetch files, or execute any join/merge/conversion; each hint names the shared value as evidence. Resolve ids first if you only have a search result. Per-id resolve failures are reported, not fatal.

  • resolve

    Description is built at runtime.

  • search

    Search public research-data archives, omics registries, and the literature for datasets, software, publications, and sequencing data. Fans out across Zenodo, DataCite (Dryad, Figshare, Dataverse, OSF, Mendeley, OpenNeuro), NCBI omics (GEO, SRA, BioProject), literature (PubMed + OpenAIRE), HuggingFace Hub (datasets), DataONE (eco/environmental federation), OmicsDI (proteomics/metabolomics), RCSB PDB (macromolecular structures), GWAS Catalog (genotype-phenotype studies), OpenML (ML datasets), DANDI (neurophysiology dandisets), CZ CELLxGENE (single-cell datasets), GBIF (biodiversity datasets), da…
