<!-- common payload: stats associated with data -->
type StatsRange = {
  max: number, min: number
}

type StatsKeys = 'count' | 'aum' | 'priceusd' | 'value'

type PartialStats = {
  stats?: {
    [key in StatsKeys]?: StatsRange
  }
}

<!-- common payload: pagination info -->
type Pagination = {
  pagination?: {
    currentPage: number,
    perPage: number,
    total: number,
    totalPages: number
  }
}

<!-- api: onboarding data -->
type APIResponseOnboards = {
  count: number,
  unixTimeStamp: number,
  timestamp: string,
}

<!-- api: historical data -->
type APIResponseHistorical = {
  aum: number,
  unixTimeStamp: number,
}

<!-- api: wallets data -->
type APIResponseWallets = {
  wid: number,
  tenant: number,
  portfolioValue: number,
  address: string,
}

<!-- all api data handling -->
interface APIResponseData extends PartialStats, Pagination {
  data : {
    data: APIResponseOnboards[] | APIResponseHistorical[],
    field?: string,
    grouping?: string
  }[] | APIResponseWallets[],
}
