PRIDE API

healthy 4,443 Subscribers

The PRIDE proteomics archive as an API, powered by the EMBL-EBI PRIDE Archive — the world's largest public repository of mass-spectrometry proteomics data and a founding member of ProteomeXchange. Search the public proteomics experiments by keyword (returning each project's accession, title, organisms, diseases and instruments); read a project's full metadata including its description, keywords, organisms and organism parts, mass-spectrometry instruments, software, the protein modifications identified, sample- and data-processing protocols, submitters, affiliations and the linked publication (DOI and PubMed); list a project's data files with their category, format, size and a direct download link; and explore facets — the diseases, organisms, instruments, experiment types, software and countries represented across matching projects — for discovery. Ideal for proteomics and systems-biology research, dataset reuse and meta-analysis, bioinformatics pipelines, and tools that integrate experimental evidence. Project accessions look like PXD000001. Data from EMBL-EBI.

UniProt API

The UniProt protein knowledge base as an API, powered by the official UniProt REST service curated by EMBL-EBI, SIB and PIR. Look up any protein by its UniProt accession for protein and gene names, organism, length, mass, function, keywords, Gene Ontology (GO) terms and linked PDB 3D structures; run full-text protein searches filtered by organism (NCBI taxon id) and Swiss-Prot review status; fetch amino-acid sequences with FASTA, molecular weight and CRC64 checksum; list sequence features such as signal peptides, chains, domains, active and binding sites, modified residues and natural variants, with a by-type breakdown; resolve NCBI taxonomy nodes with their full lineage; and pull reference proteomes with protein counts and genome-assembly ids. Across all kingdoms of life, from human to bacteria. Ideal for bioinformatics pipelines, drug-discovery and proteomics tools, sequence-analysis dashboards, academic research apps and life-science chatbots.

MetaboLights API

MetaboLights as an API, powered by EMBL-EBI — the world's premier open repository for metabolomics experiments (NMR spectroscopy and mass spectrometry) and a sister resource to PRIDE for proteomics. Search the public metabolomics studies by keyword (returning each study's accession, title, description and organism); read a study's full metadata including its abstract, status, submission and release dates, study-design descriptors, experimental factors, the analytical assays with their measurement type, technology and platform, the contributors and their roles, the linked publications with DOI and PubMed identifiers, submitters, sample count, FTP download URL and data license; inspect the analytical workflow — every protocol with its name, type, description and parameters (sample collection, extraction, chromatography, NMR/MS spectroscopy, data transformation and metabolite identification); and list the organisms and organism parts studied with their ontology terms. Ideal for metabolomics and systems-biology research, dataset reuse and meta-analysis, bioinformatics pipelines and tools that integrate experimental evidence. Study accessions look like MTBLS1. Data from EMBL-EBI MetaboLights.

Gene Expression API

Functional-genomics experiments as an API — powered by NCBI GEO (Gene Expression Omnibus), the largest public repository of gene-expression data. GEO archives expression series and curated datasets from microarray and high-throughput-sequencing experiments across every organism. Search experiments by keyword and optionally by organism, and look up any series or dataset to get its metadata: title, summary, assay type (expression profiling by array or by sequencing), organism, number of samples, platform and the publication behind it. From β-cell stress studies to cancer transcriptomics across human and mouse, it turns the GEO archive into a simple search-and-fetch API for transcriptomics, bioinformatics and research-data discovery. A gene-expression / functional-genomics dataset repository — distinct from sequence (ENA), variant (ClinVar, dbVar), structure (PDB) and ontology databases. Open data from NCBI GEO (public domain).

DataCite API

DataCite as an API — the global registry of DOIs (Digital Object Identifiers) for research outputs. Where Crossref registers DOIs for journal articles, DataCite registers and describes DOIs for research data, software, samples, dissertations, preprints, models, images and other outputs, from repositories such as Zenodo, Dryad and thousands of institutions. /v1/search?query=climate full-text searches the registry and can be narrowed by resource type (type=dataset, software, text, image, audiovisual, collection, model and more), returning each DOI with its title, type, creators, publisher and publication year. /v1/doi?id=10.5281/zenodo.3509134 returns a single DOI's full metadata — title, resource type, creators, publisher, publication year, description, subjects, version, license and registration date. DOIs look like 10.5281/zenodo.3509134 (Zenodo) or 10.5061/dryad.xxxx (Dryad). Ideal for research-data discovery and citation, data-repository and reference-management tools, software-citation features and reproducibility workflows. Metadata is CC0 from DataCite. This is the registry of research data and software DOIs — distinct from the journal-article DOI index (Crossref) and from preprint and open-access services.
