4TU.ResearchData API is one of 3 APIs that [Delft University of Technology](https://apis.io/providers/tu-delft/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. This API exposes 1 JSON Schema definition. Tagged areas include Research Data, Open Data, Repository, REST, and FAIR. The published artifact set on APIs.io includes an OpenAPI specification, authentication docs, API documentation, a support channel, and 1 JSON Schema.

Public REST API for the 4TU.ResearchData repository, the science/engineering/design research data repository of the 4TU.Federation, hosted and operated by TU Delft Library. Twelve endpoints verified live and unauthenticated on 2026-08-19: dataset listing, search, retrieval, files and versions on /v2; datasets and depositing groups on /v3; plus the license and category vocabularies. Depositor endpoints under /v2/account/ take an opaque personal bearer token. The /v2 surface is backward compatible with the Figshare v2 API shape as a migration requirement — uuid supersedes the numeric id and usage errors return precise HTTP codes rather than a blanket 400. Datasets carry versioned DataCite DOIs under the 10.4121 prefix and expose ORCID iDs on author records.
