} = ShipupETA.fetchPredictions(
  {
    origin,

    order
  }
)

origin: OriginAddress
- the origin address that will be used by the algorithm
- defaults to the address of your default warehouse if no defaultOriginAddress was specified in calls to ShipupETA.init
destination: Address
- the destination address that will be used by the algorithm
- defaults to the address of your default warehous if no defaultDestinationAddress was specified in calls to ShipupETA.init
carriers: Carrier[]
- the list of carrier services for which you want a delivery estimation
- defaults to all carrier services enabled on your account
order: OrderOptions
- options that allow you to specify key dates for the delivery estimation
  - ordered_at: the time at which the order was placed
    - defaults to the current time
  - order_processing_time: Processing time for order in days.
    - defaults to the warehouse's processing time.
  - merchant_shipping_date: the time at which the order was shopped
    - if left empty, Shipup will predict a shipping date and use it to predict the delivery date
    - ⚠️ only fill this field if you know exactly when the order will be shipped (e.g. for pre-orders or product sent on a specific date of the month)

delivery_date_estimations: Prediction[]
- the list of predictions for the request carrier services
best_estimation: Prediction
- the fastest delivery prediction for a carrier service
- the carrier service is selected by first comparing the delivery_date values, then the safe_delivery_date in case of equality
