interface EndpointResponse {
  results: Record<string, unknown>[];
  columns: string[];
  hasMore: boolean;
}

async function callEndpoint(endpointName: string): Promise<EndpointResponse> {
  const response = await fetch(
    `<ph_app_host>/api/environments/{project_id}/endpoints/${endpointName}/run`,
    {
      headers: {
        "Authorization": `Bearer ${process.env.POSTHOG_PERSONAL_API_KEY}`
      }
