    Early access: contact support@ploti.ai to set up a subscription.

    Public records from the places your workspace covers, delivered to your
    own systems. Subscribe to counties, load each dataset's snapshot once,
    then apply each new version's changes as Ploti publishes them.

    Every call acts as the workspace member who holds the API key. Lists that
    page take `limit` and `cursor` and return `nextCursor`, null on the last
    page. Fields are camelCase. A refusal is
    `{ "error": { "code", "message", "links" } }`.
