Crossref DOI Registration Membership is one of 8 APIs that [Kyushu University](https://apis.io/providers/kyushu/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Crossref, DOI, Registry, Scholarly Publishing, and Persistent Identifiers.

Two Kyushu University units are Crossref members registering DOIs under their own prefixes, verified against api.crossref.org on 2026-09-01 — member 3044 "Kyushu University" (prefix 10.5109, 6,284 DOIs) and member 1036 "Faculty of Mathematics, Kyushu University" (prefix 10.2206, 1,527 DOIs). A membership, not a contract the institution publishes; Crossref's API is Crossref's and is not saved here.
