The fine print

License note: CC0, version not stated: the licence page names Creative Commons Zero for RNAcentral data but links an unversioned Creative Commons page, so Custom. Signal Lab links only.
Required attribution: Not required under CC0; citing RNAcentral is good practice.

// Overview

RNAcentral API (non-coding RNA sequences, EMBL-EBI)

RNAcentral is EMBL-EBI's database of non-coding RNA sequences aggregated from expert member databases. Its keyless REST API returns sequences with RNAcentral identifiers, lengths and cross-references to the source databases, as JSON.

Verdict

A sequence-reference source for bioinformatics pipelines, alongside uniprot-rest-api. Licence: Custom (CC0, version not stated): the licence page says "All RNAcentral data are freely available under the Creative Commons Zero license (CC0)" and "This means that any form of reuse of the content is permitted". Its CC0 link points to a general Creative Commons page, not a versioned CC0 deed, so no version is claimed. Rate limits: Not stated. Signal Lab links only.
