# List supported 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.
