Research Funding API

healthy 3,175 Subscribers

Discover the funding and projects behind research — as an API over OpenAIRE, the open research graph that links scholarly outputs to the grants and funders that paid for them. Search funded research projects (grants) by keyword and filter by funder — the European Commission, NIH, NSF, UKRI, DFG, Wellcome and many more — and get each project's title, grant code, acronym, funder, start and end dates, funded amount and summary. Search publications too, with their title, authors, year, DOI, type, publisher, open-access status and whether they were publicly funded. It is the place to find research grants and the money behind science — ideal for research-funding discovery, science-policy analysis, grant intelligence, reporting and open-science tooling. A research-funding / projects resource — distinct from DOI registries (Crossref, DataCite) and scholarly-metadata indexes (OpenAlex). Open data from OpenAIRE (CC BY).

US Government Spending API

US federal government spending as an API, live from the official USAspending.gov (US Treasury). Search federal awards — contracts, grants, loans and direct payments — by keyword, recipient, award type and fiscal year, ranked by amount, with the recipient name, dollar amount, awarding agency, description and award dates. Rank the top recipients of federal money for any search, and list and inspect the 100+ top-tier federal agencies with their budgetary resources. Ideal for government-transparency, investigative journalism, contractor intelligence, grants research, GovCon and policy-analysis applications. Public-domain US Treasury data.

Research Organizations API

Every research organization in the world as an API — powered by ROR, the Research Organization Registry. ROR assigns a persistent open identifier (a ROR ID) to universities, government labs, companies, nonprofits, hospitals, archives and research facilities, with rich, curated metadata and crosswalks to GRID, ISNI, Wikidata and the Crossref Funder Registry. Search the registry by name (and filter by country or organization type); resolve any ROR ID to its full record — names, acronyms and aliases, types, location (city, country, coordinates), website, domains, external identifiers and relationships to parent and child organizations; and match a messy free-text affiliation string ("Dept. of Physics, Heidelberg University, Germany") to the most likely organizations with a confidence score — perfect for cleaning and disambiguating author-affiliation data. It is a research-organization identifier registry, distinct from a plain university directory, and a natural companion to ORCID (for people) in any scholarly-metadata stack. Open data from ROR (CC0).

OpenCitations API

Scholarly citations as open data — powered by OpenCitations (COCI), the open citation index. Unlike a metadata lookup, OpenCitations treats every citation as a first-class object: given a DOI you can list the papers that cite it (incoming citations) and the papers it references (outgoing), each annotated with its OpenCitations Identifier (OCI), the date the citation was created, the timespan between the two works, and whether it is a journal- or author-self-citation. Plus quick citation and reference counts for any DOI. It is built for citation-network and bibliometric work — research-impact analysis, self-citation detection, citation-timespan studies and science mapping — and is distinct from scholarly-metadata services (Crossref, OpenAlex). From a single paper to a whole reference graph, ideal for bibliometrics, research-analytics and reference-management tools. Open data from OpenCitations (CC0).

DOAJ API

The Directory of Open Access Journals as an API, powered by DOAJ — the authoritative, community-curated index of vetted open-access scholarship covering more than 20,000 quality-controlled journals and 10 million+ articles across every discipline. Search open-access journals with full Elasticsearch query syntax, getting each journal's title, ISSNs, publisher and country, subjects, languages, whether article-processing charges (APC) apply, license and the year it became open access; read a journal's complete record including its subjects with classification scheme, keywords, licences, APC prices, fee-waiver policy, peer-review process, plagiarism detection, long-term preservation and self-archiving (deposit) policies and homepage; search open-access articles returning title, authors, journal, year, DOI, keywords and a free full-text link; and read an article's full metadata with its abstract, authors and affiliations, journal and ISSNs, pages, subjects and direct links to the freely readable full text. Ideal for open-science tooling, library and repository systems, research discovery, APC and policy analysis, and any application that needs legally free, peer-reviewed scholarship. Identify a journal by its ISSN and an article by its DOI or DOAJ id from search results. Data from DOAJ.
