MarineCadastre AccessAIS is NOAA/BOEM's interactive clip-and-ship tool for ordering historical AIS broadcast point data for a user-defined area and time window in U.S. waters. It is a separate product from MarineCadastre's annual AIS vessel-transit count rasters: AccessAIS delivers filtered broadcast points (not transit grids or live AIS), with new point years added quarterly and individual orders capped at 2 GB.

NOAA Office of Coast Survey publishes official U.S. Electronic Navigational Charts (ENC) as S-57 databases of nautical chart features for download from the Chart Locator and regional ENC download pages.

OpenAlex is a nonprofit, open index of scholarly works, authors, sources, institutions, topics and more, served as a REST API that returns JSON. Each entity type is an endpoint (/works, /authors, /sources and others) that can be listed, filtered, searched, sorted, grouped into counts and paged, and OpenAlex says "all data is CC0". Basic queries work with no key; a free key raises the daily budget 10x.

Crossref's public REST API exposes the scholarly metadata that Crossref members and trusted sources deposit: bibliographic records plus funding data, licence information, post-publication updates, ORCID and ROR IDs and, for some records, abstracts. Works, journals, members, funders, prefixes, types and licences can be searched, filtered, faceted or sampled, with results in JSON; no sign-up is required.

arXiv's public API returns search results and metadata for arXiv e-prints as an Atom XML feed: titles, abstracts, authors, categories, identifiers, dates and links to each abstract page and PDF. Queries can target fields with prefixes such as ti (title), au (author), abs (abstract) and cat (category), be sorted by date and paged; no key is needed. arXiv also offers OAI-PMH, RSS feeds and bulk data downloads under the same API terms.

NCBI's Entrez Programming Utilities (E-utilities) are the public API to PubMed, NLM's database of citations and abstracts of biomedical literature, of which MEDLINE is the largest component. ESearch returns PubMed IDs for a query, and ESummary or EFetch return the records in JSON or XML; no key is needed for up to three requests a second.

DataCite's public REST API returns JSON metadata for DOIs registered with DataCite, which include research datasets, software and other research outputs: titles, creators, publisher, publication year, resource type, rights, related identifiers and landing-page URLs. Retrieval needs no authentication and supports queries, filters such as resource-type-id, paging and random samples.

DOAJ's public API searches its directory of open access journals and the article records held for them: titles, journal, year, identifiers such as DOI and ISSN, abstracts and full-text links, plus journal details such as the licence. Search routes take Elasticsearch query-string syntax with short field names such as title, doi, issn and publisher; no key is needed to search, as DOAJ API keys are mainly for publishers who submit data.

Zenodo, the open repository hosted by CERN, has a REST API for searching its published records of any resource type, such as publications, reports, datasets and software, and returning their metadata and file links in JSON, plus OAI-PMH harvesting. Public records search works without a key under Zenodo's published guest limits (60 requests a minute and 2,000 an hour; search endpoints 30 a minute); a free Zenodo account and access token give higher limits and are needed for authenticated and deposit operations. Zenodo's developer docs also say broadly that "All API access requires an access token".

The OSTI.GOV API from the U.S. Department of Energy's Office of Scientific and Technical Information queries DOE's repository of research information resulting from DOE research funding: technical reports, journal articles and accepted manuscripts, datasets, software, patents, conference papers and more. Records come back as JSON, XML or BibTeX, 20 per page by default, with paging links in the Link header; no key is needed.

The OpenAIRE Graph API queries the OpenAIRE Graph, which aggregates metadata from a wide range of scholarly resources into linked records for research products (such as publications), data sources, organizations, projects and persons. Parameter-based and filter-based query styles return JSON with paging, and the filter-based style adds faceted counts and field selection. Unauthenticated requests are allowed.

OpenCitations publishes open bibliographic citation data through REST APIs: OpenCitations Index returns, for a DOI or other identifier, the citations to a work and the references it makes, each citation with its own Open Citation Identifier (OCI), creation date and timespan, and OpenCitations Meta returns bibliographic metadata for works. Results are JSON by default or CSV; an access token is optional and encouraged for code.

The World Bank Documents & Reports API searches and retrieves records for the public World Bank documents on its Documents & Reports site, returning JSON or XML. Queries can match words across core fields or target fields such as title, country, language, document type and date range, with facets, sorting and paging, and each record links to the document page and PDF; no key is needed.

Statistics Canada's Web Data Service (WDS) is a keyless REST API for data and metadata in the agency's main output database. JSON methods expose changed tables and series, table metadata, vector and coordinate time series, date-range queries, code sets, and links to full-table CSV and SDMX downloads. It is the general API across Statistics Canada tables, distinct from individual table entries in this catalog.

The UK Office for National Statistics API makes datasets, editions, versions, dimensions, options and observations available over keyless HTTP. It supports dataset discovery and filtered observation-level JSON from the ONS Explore our data service. The API is open and unrestricted, requires no API key, and is currently labelled Beta.
