healthy 3,308 Subscribers

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.

DEV (dev.to) API

The DEV Community (dev.to) as an API, powered by the official open-source Forem platform API. DEV is one of the largest communities of software developers writing and sharing articles, tutorials and discussions. This API gives clean, read-only access to that content. /v1/articles browses and filters published articles — by tag (tag=javascript), by author (username=ben), by most-reacted over a period (top=7 for the best of the last week), or by feed state (fresh, rising) — with pagination; each result carries the title, description, canonical URL, tag list, positive-reaction and comment counts, estimated reading time, cover image and author summary. /v1/article?id=5 returns a single article with its complete Markdown body, canonical URL and author social links — everything needed to render or syndicate the full post. /v1/user?username=ben returns a member's public profile: display name, bio/summary, location, join date, linked Twitter/GitHub/website and avatar. /v1/tags lists the platform's popular tags for discovery. Article ids are numeric and stable, so links don't rot. Ideal for developer-content aggregators and newsletters, reading-list and bookmarking apps, community dashboards, "trending in tech" widgets and Discord/Slack bots. Data from the public DEV Forem API, free to use. Content is authored by the DEV community.

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). Open data from OpenAIRE (CC BY).
