  description: >
    Routes the Anona Compute gateway serves next to the E2B-compatible API:

    live-view viewer tokens, SSH certificates, network policy, the credential

    vault, usage and billing, webhooks and telemetry export, thumbnails, preview
    links,

    public ports, pause when idle, template builds, and API key management.

    (`gateway/internal/stream/token/handlers.go`,

    `gateway/internal/sshca/handler.go`,
    `gateway/internal/handlers/apikeys/apikeys.go`)

    and checked against a running gateway by
