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.

 Habr Tech Community API — oanor API marketplace

Habr Tech Community API

Articles, ratings and topic hubs from Habr (habr.com), the largest Russian-speaking technology community, read keyless from its public web API. Habr is where Russian-speaking engineers, scientists and companies publish deep technical articles, and where the community judges them with a signed rating (up-votes minus down-votes) — a score that can go negative, quite unlike a likes-only model. Alongside the rating, every article carries its read count, bookmarks (saves) and comments, and lives in one or more "hubs" (topic communities). The articles endpoint lists the top articles, ranked either by rating over a period (day/week/month/year/all-time) or by date, each with its signed score, vote count, reads, bookmarks, comments, author, hubs and reading time. The article endpoint returns one article in full by its numeric id. The hubs endpoint lists Habr's topic hubs with their subscriber counts and hub rating — the map of Russian tech's interests (AI, information security, programming and the rest). This is the Habr platform cut — a distinct social and developer platform, separate from the Western (dev.to) and Japanese (Qiita) developer communities in the catalogue, with its own signed-rating model and Russian-language community. Scores, reads and subscriber counts are the real, live numbers; a negative score is real, not an error. Titles and hubs are in Russian as Habr publishes them. A short cache fronts the upstream. Keyless.
