{"openapi":"3.1.0","info":{"title":"DataCite API","version":"1.0.0","description":"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.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/datacite-api","description":"oanor
