# Get API compatibility information

Returns API compatibility information including the current breaking generation
            and minimum supported generation. This endpoint is version-agnostic (not under /api/v1),
            unauthenticated, and always available.

            Clients should embed COMPILED_BREAKING_GENERATION at build time and use this endpoint
            to determine compatibility:
            - If client_generation < min_supported_generation: block usage and force update
            - If client_generation < breaking_generation: optional update warning
            - Otherwise: proceed normally

            This endpoint must remain backward-compatible indefinitely.

  - `min_supported_generation` (integer, required)
    Minimum generation that clients must have been compiled against to be allowed to operate. Clients compiled against a lower generation must update.
