Crossref membership (DOI registrant) is one of 8 APIs that [National University of Colombia](https://apis.io/providers/national-university-of-colombia/) publishes on the [APIs.io](https://apis.io/) network.

UNAL is a Crossref member in its own right — member id 6146, DOI prefix 10.15446 — with a second member record for its Faculty of Sciences, member id 21512, prefix 10.36385. This is a fact about UNAL held on Crossref's host, machine-readable at api.crossref.org, and it is recorded as a membership, never as a UNAL-operated API. Crossref's own contract is not saved here. Verified live 2026-09-01 (200). By contrast, a search of api.datacite.org for UNAL returns zero providers: the repository mints Handles, not DataCite DOIs.
