List supported languages
The canonical BCP 47 catalogue. Validate a language against this before attempting a glossary write, rather than learning from a 422. Identical for every workspace, and cacheable for an hour.
GET/v1/languages
This public, cacheable endpoint is identical for every workspace. Use it before accepting a language or constructing a glossary pair instead of discovering invalid input through a 422 response.
It requires no workspace data, changes nothing and consumes no credits. MCP exposes the same catalogue as the aiglot://languages resource rather than as a tool.
