The SelectRate Insurance Rating API allows insurance organizations to integrate commercial insurance rating directly into agency management systems, policy administration systems, underwriting workbenches, broker portals, customer portals, mobile applications, and third party software. Built on a modern API first architecture, SelectRate exposes every major rating capability through secure REST APIs, enabling organizations to deliver real time premium calculations without duplicating rating logic across multiple applications. Whether you're building a new insurance platform or modernizing legacy systems, the Insurance Rating API provides a single source of truth for commercial insurance pricing.

Why an Insurance Rating API?

Many insurance organizations maintain separate rating logic across portals, desktop applications, policy administration systems, and spreadsheets. This creates inconsistencies, increases maintenance costs, and makes product changes difficult to manage. The SelectRate Insurance Rating API centralizes all rating logic within a single enterprise platform. Every application calls the same rating engine, ensuring accurate, consistent, and governed premium calculations regardless of where the quote originates.

One Rating Engine. Multiple Applications.

A modern insurance rating API allows every application to use the same centralized rating engine. Instead of maintaining separate rating logic across portals, policy administration systems, broker applications, and internal tools, organizations expose one enterprise rating engine through secure APIs. This improves consistency, simplifies maintenance, and accelerates product changes.

Instead of maintaining multiple rating systems, organizations can expose a single commercial insurance rating engine to every business application.
