The API provides more information on available versions and languages contained in the API

Top level foundation endpoint /icd/entity as well as top level linearization endpoints /icd/release/11/{releaseId}/{linearizationname} contain more information on available releases and languages available in the API.

The response of /icd/entity now has allreleases that lists all releases deployed and availableLanguages that list all languages available. This list includes all languages, whether they are available in only one classification or in prerelease status.

In the response of /icd/release/11/{releaseId}/{linearizationname}, availableLanguages shows the languages available for that linearization. For example, to see all languages available for ICF in the 2026-01 release you could call /icd/release/11/2026-01/icf.
In this output, prereleaseLanguages shows if some of the languages are in prerelease stage.
