SmartRate Guide
The SmartRate API provides shippers with highly accurate, shipment-level transit time predictions. Users can leverage this data to make informed decisions about shipping strategies to save money, improve on-time delivery, and get reliable estimated delivery dates.
The SmartRate API offers users 500 free SmartRate API calls for immediate use. Once the 500 call limit is exceeded, users are charged $0.03 per call or can sign up for a subscription.
Note: The SmartRate API is currently available exclusively for US domestic shipments.

The SmartRate API accepts a Shipment ID and returns a time_in_transit object that includes transit days across various percentiles for every Rate associated with a given Shipment. Transit days are calculated as the number of business days from when the carrier first acknowledges possession of the shipment to the initial out-for-delivery attempt.
The /smartrate endpoint accepts a Shipment ID and returns a time_in_transit object that includes transit business days across various percentiles for every Rate associated with a given Shipment. Transit business days are calculated as the number of business days (Monday-Friday) from when the carrier first acknowledges possession of the shipment to the initial out-for-delivery attempt.

The /delivery_date endpoint provides estimated delivery dates for shipments, helping users identify cost-effective service levels and enhance delivery timeliness.
This data helps identify cheaper service levels that meet time-in-transit Service Level Agreements (SLAs), enhance on-time delivery for time-sensitive shipments, and improve customer experience with accurate delivery date estimates.
Unlike the /smartrate endpoint, the days_in_transit uses complex AI to consider the day of the week planned for shipping and account for shipments that extend over weekends and holidays.

The /precision_shipping endpoint of the SmartRate API enhances shipping accuracy by allowing shippers to specify a desired delivery date. The API then suggests the best ship date for each carrier and service level to meet this delivery date. In addition to the suggested ship_on_date, a delivery_date_confidence score is provided, indicating the likelihood of delivery on the desired date.

The /smartrate/deliver_by endpoint offers advanced predictions of delivery dates based on the entry point into the mailstream and intended delivery timelines.
This time-in-transit data can be used in offline processes to identify cheaper service levels that meet time-in-transit Service Level Agreements (SLAs), enhance on-time delivery for time-sensitive shipments, and improve customer experience with accurate delivery date estimates.

To utilize SmartRate, first create a shipment for the parcel. Once the shipment is created, copy the shipment_id from the bottom of the response for the next step.
Refer to the Getting Started Guide for detailed instructions on creating a shipment.
Using the shipment_id, choose the appropriate SmartRate endpoint based on the shipping schedule or delivery requirements.
NOTE: The Deliver By and Deliver On endpoints do not require a Shipment ID.
Use the response to select the most appropriate rate for the shipment.
Identify cost-effective service levels that meet your transit time requirements. SmartRate provides granular, accurate transit time estimates, enabling cost savings on both shipping and packaging.
Improve on-time delivery rates and checkout experiences by providing reliable delivery date estimates directly to customers. This is especially beneficial during peak seasons when carrier performance may vary.
