Shipping Analysis and Optimization

Geographic Cost Analysis

Confirm origin address, destination list (or use representative cities), and parcel details.
Call ListCarrierAccounts to see configured carriers.
Call CreateShipment per destination to collect rates. Creating shipments is free; only CreateTransaction costs money.
Write results to analysis/ directory (markdown report + CSV). Columns: Route, Destination, Carrier, Service, Cost, Currency, EstimatedDays, Zone.

Package Optimization

Confirm the route.
Define dimension profiles to test (or use user-provided ones).
Check ListCarrierParcelTemplates and ListUserParcelTemplates for flat-rate and saved templates. See shippo/references/rate-shopping-guide.md for dimensional weight and flat-rate guidance.
Call CreateShipment per profile on the same route.
Compare: cheapest rate, carrier options, fastest option per profile. Note where flat-rate templates beat custom dimensions and where dimensional weight causes price jumps. See shippo/references/carrier-guide.md for carrier-specific weight limits and surcharges.

Carrier Comparison

Call CreateShipment for the route.
Group the rates array by provider.
Per carrier: cheapest service, fastest service, number of service levels, price range.

Historical Cost Optimization

Call ListShipments and ListTransactions to get past activity.
Cross-reference: what the user paid vs. what alternatives were available.
Identify patterns: carrier concentration, service-level mismatch, consistent overpayment.
For a sample of shipments with tracking numbers, call GetTrack to check actual vs. estimated delivery times.
If fewer than 5 successful transactions exist (not just shipments -- shipments are rate quotes, transactions represent actual spend), redirect to forward-looking analysis.

Output Conventions

Write reports to the analysis/ directory. Create it if it does not exist. Include both markdown and CSV. CSV must have a header row. Markdown must include a timestamp and input parameters.

Quick Reference

Cost analysis: ListCarrierAccounts -> CreateShipment (per destination) -> read rates arrays -> write report

Carrier comparison: CreateShipment -> group rates by provider -> summarize

Historical review: ListShipments + ListTransactions -> cross-reference -> GetTrack (sample) -> write report
