# Preview a scenario batch's validation

> A side-effect-free read that validates a scenario batch document without saving anything: schema shape, closed enums, per-check rules, and — when automationId is given — whether each scenario's trigger selection would admit against the automation's live triggers. Shape and rule issues depend only on the document; the trigger findings reflect the automation's triggers when the request is made, and a schedule scenario without an occurrence is judged against the current time.

    The Recursion Managed Agents REST API. Authenticate with a Recursion API key
    as a bearer token. An organization-scoped key acts in its own organization
    and needs nothing else; a tenant-scoped key must also send
    `x-organization-id` with an organization id or `default`. Field names follow
    each operation's published schema.
