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.

Product end-of-life and support-lifecycle dates as an API, powered by endoflife.date — the community-maintained reference for when software stops being supported. Covers 450+ products across every layer of the stack: Linux distributions (Ubuntu, Debian, RHEL, Alpine…), programming languages (PHP, Python, Node.js, Java, Go, Ruby…), frameworks (Django, Laravel, Spring Boot, React, Angular…), databases (PostgreSQL, MySQL, MongoDB, Redis…), operating systems, browsers, hardware devices and more. List every tracked product; for any product get all of its release cycles with the release date, latest patch version and release date, LTS flag, active-support end date and end-of-life date; and look up a single release cycle on its own. Every cycle is enriched with a computed, live status calculated against today's date — whether the version is still supported, whether it has already reached end of life, how many days remain until end of life and whether active support has ended — so you can answer "is this version still supported?" and "how long until I must upgrade?" in one call. Ideal for dependency auditing, upgrade and migration planning, security and compliance dashboards, CI checks and platform inventories. Product slugs come from the products endpoint (e.g. php, ubuntu, nodejs, postgresql). Computed status is relative to the current UTC date. Data from endoflife.date (CC-BY-SA).

The full SPDX License List as an API — all 729 software licenses with metadata and the complete license text for each. Look up any license by its SPDX id (e.g. MIT, Apache-2.0, GPL-3.0-only, MPL-2.0) and get the exact, canonical license text plus its name, reference URL, see-also links and standard header. Search or list licenses by name/id and filter by OSI-approved (Open Source Initiative), FSF-libre (Free Software Foundation) or deprecated status. Ideal for SBOM / license-compliance tooling, package managers, repository scanners, legal review, and open-source governance dashboards.
