Eurostat API

Official European Union statistics as an API, powered by Eurostat — the statistical office of the EU. Eurostat publishes harmonised data across every EU and EFTA country and region: population and demography, GDP and national accounts, employment and unemployment, inflation (HICP), trade, energy, migration, education, health and thousands more datasets. This API wraps Eurostat's JSON-stat dissemination service into clean, decoded rows, and adds friendly named indicators so you don't have to learn dataset codes. /v1/indicator?indicator=population&geo=DE&year=2023 returns a named statistic — population, gdp, gdp_per_capita, unemployment, inflation or employment — for one or more countries (2-letter codes such as DE, FR, IT, or aggregates like EU27_2020 and EA20) and one or more years, with no need to know the underlying dataset or dimension codes. /v1/data?dataset=demo_pjan&geo=DE&sex=T&age=TOTAL&time=2023 gives direct access to any of Eurostat's thousands of datasets by its code, with arbitrary dimension filters passed as query parameters — every dataset has its own dimensions (geo, time, sex, age, unit, na_item, coicop and so on). Both endpoints decode Eurostat's JSON-stat format automatically: single-value dimensions are lifted into a `fixed` context block, and each row carries the dimensions that actually vary (with both a human-readable label and the underlying code) alongside the numeric value, the dataset label and the last-update date. Ideal for economic dashboards, country comparison tools, research, data journalism and policy analysis. Country codes are 2-letter ISO; aggregates include EU27_2020 and EA20.

OpenSky API

Live air traffic as an API, powered by the OpenSky Network — a community network of thousands of volunteer ADS-B/Mode-S receivers tracking aircraft worldwide in real time. This is live flight tracking, the FlightRadar-style picture of what is in the sky right now, distinct from static aircraft registries, airline directories, airport metadata and scheduled-flight status. /v1/flights returns every aircraft currently airborne inside a geographic bounding box (give the box as lamin/lomin/lamax/lomax in degrees, kept under roughly 20° latitude by 30° longitude), each with its ICAO 24-bit address, callsign, origin country, live longitude and latitude, barometric and geometric altitude, ground speed, true heading, vertical rate and transponder squawk — a real-time radar snapshot with the network timestamp. /v1/aircraft looks up a single aircraft by its 6-hex ICAO 24-bit address and returns its current live state (or airborne:false when it is grounded or out of receiver range). /v1/arrivals and /v1/departures list the flights that arrived at or departed from an airport (4-letter ICAO code such as EDDF Frankfurt or EGLL Heathrow) over the last N hours (1-48), each with callsign, the estimated airport at the other end and the first/last-seen timestamps. Ideal for live flight-tracking maps, aviation dashboards, geofencing and proximity alerts, spotting tools, and research into air-traffic patterns. Positions are in degrees, altitudes in metres and speeds in metres per second. Data from the OpenSky Network, free for non-commercial use — please credit OpenSky. Coverage depends on volunteer receiver density.

Codeforces API

Codeforces as an API — the largest competitive-programming platform, running regular rated rounds for hundreds of thousands of programmers worldwide. This API wraps the official Codeforces API into a clean, predictable JSON service. /v1/user looks up one or many competitors' profiles — current and maximum rating with the corresponding rank/title (from newbie through grandmaster to legendary grandmaster), contribution score, country, city, organization, registration date and avatar. /v1/rating returns a competitor's full rating history, contest by contest, with the old and new rating, the rating change and the rank achieved in each round — ideal for plotting a rating curve. /v1/contests lists upcoming and past contests, filterable by phase (BEFORE for the schedule of upcoming rounds, FINISHED for the archive), each with start time, duration and type. /v1/problems searches the entire Codeforces problemset by tag (dp, graphs, greedy, math, implementation, data structures and dozens more) and by difficulty-rating range, returning each problem's contest id, index, name, difficulty rating and tags with a direct link. Ratings range from ~800 to 3500+. Ideal for competitive-programming dashboards, rating trackers, training and problem-recommendation tools, and Discord/Telegram bots for CP communities. Data from the official Codeforces API, free to use. The service is resilient to Codeforces' concurrency rate-limit (automatic retry with backoff).

ENA API

The European Nucleotide Archive (ENA) as an API, powered by EMBL-EBI — one of the three INSDC partners alongside NCBI GenBank and DDBJ, and the comprehensive public archive of the world's nucleotide sequence data. ENA holds raw sequencing reads, assembled and annotated genomes, individual sequences, biological samples and the studies behind them, for every domain of life — the backbone resource for genomics, microbiology, ecology, evolution and clinical research. This API gives a clean three-step workflow over that archive. First, /v1/taxon resolves an organism name (e.g. "Homo sapiens") to its NCBI taxon id, scientific name, taxonomic rank and full lineage — or looks a taxon up directly by id. Then /v1/search queries the archive for that taxon's records of a chosen type: genome assemblies (with assembly name, level and base count), sequencing runs (with platform, instrument and read counts), biological samples (with collection date and country), annotated sequences, read experiments, analyses, coding and non-coding sequences, and studies — by default including all descendant taxa, or restricted to the exact taxon. Finally /v1/record returns a summary for any ENA accession — assemblies (GCA_…), studies and projects (PRJ…), samples (SAM…/ERS…), sequencing runs (ERR…/SRR…) and sequences — with its title, data type, taxon, scientific name, base and sequence counts and public status. Ideal for bioinformatics pipelines, genome-data discovery, sequencing-metadata harvesting, biodiversity and metagenomics tooling, and research reproducibility. Taxon ids look like 9606 (human); accessions like GCA_000001405. Data from EMBL-EBI ENA, an INSDC archive, free to use.

Cellosaurus API

Cellosaurus as an API, powered by the SIB Swiss Institute of Bioinformatics — the reference encyclopaedia of cell lines used in biomedical research. With more than 150,000 entries spanning cancer cell lines, hybridomas, induced pluripotent stem cells, and lines from hundreds of species, Cellosaurus is the authoritative catalogue researchers use to identify and validate the cell lines behind published experiments. Search the cell lines by name or keyword, getting each line's Cellosaurus accession (CVCL_…), name, category, species and disease; and read a cell line's full record — its name and synonyms, category (e.g. cancer cell line, hybridoma, stem cell), species with NCBI taxonomy id, sex, age, the disease it derives from with NCIt/ontology identifiers, the tissue or anatomical site of origin, its parent cell line and the number of derived child lines, the count of literature references and the many cross-references (to ATCC, DSMZ, ECACC, Wikidata and more), relevant web pages, and — critically for research reproducibility — whether the line is flagged PROBLEMATIC, meaning it has been misidentified or cross-contaminated, together with the explanatory notes. Ideal for laboratory quality control and cell-line authentication, biomedical and cancer research, data curation and reproducibility checks. Accessions look like CVCL_0030 (HeLa). Data from Cellosaurus (CC-BY 4.0).

Complex Portal API

The Complex Portal as an API, powered by EMBL-EBI — a manually curated, encyclopaedic database of stable macromolecular complexes: assemblies of two or more proteins (and sometimes nucleic acids, ligands or small molecules) that work together as a single functional unit, such as ribosomes, proteasomes, RNA and DNA polymerases, the spliceosome, respiratory-chain complexes and thousands more across many species. Search the complexes by keyword and optionally by organism, getting each complex's Complex Portal accession (CPX-…), name, organism, description and whether it is computationally predicted; read a complex's full curated record including its recommended and systematic names, synonyms, species, biological function, the participating subunits each with its molecule identifier (for example a UniProt accession) and stoichiometry, any associated ligands and diseases, the evidence type and cross-references to UniProt, Gene Ontology, Reactome, Wikidata and more; and pull just the subunit composition of a complex. Ideal for structural and systems biology, pathway and network analysis, protein-function research and bioinformatics pipelines. Complex accessions look like CPX-6036. Data from EMBL-EBI Complex Portal (IMEx consortium, CC-BY). For protein–protein interaction networks see the STRING API, for protein sequences UniProt, for biological pathways Reactome and for families & domains InterPro.

deps.dev API

Software supply-chain and dependency intelligence as an API, powered by deps.dev — Google's Open Source Insights service. Across six package ecosystems (npm, PyPI, Maven, Cargo, Go and NuGet) it answers the questions a registry cannot: what does installing this package actually pull in, and how healthy is the project behind it. List a package's published versions and its default version; read a specific version's declared licenses, the keys of any known security advisories, useful links (source repository, homepage, issue tracker) and related projects; resolve a version's complete TRANSITIVE dependency graph — the total dependency count, the direct dependencies and every transitive node with its exact resolved version and whether it is a direct or indirect dependency; and look up a source project's OpenSSF Scorecard — the overall security score plus per-check results for Maintained, Code-Review, Branch-Protection, Dangerous-Workflow, Vulnerabilities and more — alongside its stars, forks, open issues, license and homepage. For Go modules and Maven artifacts the package name is the full module path or group:artifact (URL-encoded automatically). Ideal for dependency auditing, software-bill-of-materials (SBOM) enrichment, supply-chain risk assessment and license-compliance tooling. Data from deps.dev (Google, CC-BY).

End-of-Life (EOL) API

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).

EU Open Data API

The European Union open-data portal as an API, powered by data.europa.eu — the official single point of access to more than 1.8 million open datasets published by the EU institutions and harvested from the national open-data portals of all 27 member states (including data.gov.uk, data.gouv.fr and GovData Germany). Search datasets across every theme — energy, health, transport, environment, agriculture, economy, justice and more — with optional filters by file format and by publishing country, getting each dataset's identifier, English title and description, publisher, source portal, country, available formats, resource count, last-modified date and licence; read a dataset's full metadata together with all of its downloadable distributions (each distribution's title, format and direct URL), plus categories, keywords, languages and temporal coverage; and explore discovery facets for any query — the most common file formats and the countries publishing matching datasets. Ideal for data journalism, civic-tech and govtech applications, research, market and policy analysis, and any tool that needs to find and download European public-sector information. Dataset identifiers come from search results; titles and descriptions are returned in English where available. Data from data.europa.eu (licences vary per dataset; most are CC-BY or public domain).
