Great questions. For API rate limits, we implemented a tiered caching strategy with 4-hour TTL for standard lanes and real-time calls only for high-value or time-critical shipments. The extension batches rating requests when possible - if planning 50 shipments on the same lane within 10 minutes, it makes one API call and applies results to all.

Contract version management was tricky. We created a contract repository service that maintains effective date ranges and automatically selects the correct contract version based on ship date. The rating extension queries this service first, retrieves applicable contract terms, then applies them to carrier API responses.
