# Research Funding API > 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).
